Brightness is the light intensity that the projector product outputs to the screen, and also the brightness of the projected image. In general, the higher the brightness of the projector, the brighter the image of the same size projected on the screen, and the clearer the image. However, the brightness of the image that our eyes can perceive is not only determined by the brightness of the projector, but also greatly related to the intensity of the ambient light and the size of the image. The stronger the ambient light, the dimmer the brightness of the image perceived by our eyes. Therefore, users must choose the appropriate brightness according to the environmental conditions of their projector. It is not necessarily as bright as possible. In the case of the same other indicators, the higher the brightness is, the higher the price of the projector will be. At the same time, the brightness of the image perceived by our eyes will have a certain range. Beyond this range, the our eyes will feel uncomfortable, especially after watching the image with high brightness for a long time. Our eyes will feel tired and may get hurt to some extent.

It is necessary to remind the user that in addition to choosing the brightness index according to the space size, the user should also consider the lighting conditions of the use environment, screen type and other factors. Under the same brightness, different ambient light conditions and different screen types will produce different display effects. When users choose projector products, they should have a margin for brightness index. Because the brightness of the projector largely depends on the light bulb in the projector, the brightness output of the light bulb will decline with the use time, which will inevitably cause the brightness of the projector to be declined. After 2000 hours of use, the brightness of the projector product decays rapidly, so when users choose the projector product, they must have a comprehensive consideration of the brightness index.

Generally speaking, in the 40-50 square meters of home or reception hall, it is recommended to choose 800-1200 lumens for projector brightness, and 60-72 inches for screen; in the 60-100 square meters of small conference room or standard classroom, it is recommended to choose 1500-2000 lumens for projector brightness, 80-100 inches for screen; in the 120-200 square meters of medium conference room and ladder classroom, it is recommended to choose 2000-3000 lumens for the brightness of the projector, and 120-150 inches for the screen; in large conference rooms or auditoriums with an area of 300 square meters, professional engineering machines with an area of more than 3000 lumens should be selected most projectors, and the screens should be more than 200 inches.

1. Entry-level individual users

Generally speaking, we should first pay more attention to economic practicability and ease of use, instead of chasing too high resolution. Even for image processing enthusiasts, a resolution of 600dpi can meet the basic requirements. In terms of ease of use, attention should be paid to whether there is a detailed installation and use manual attached, whether the scanning software interface is easy to understand and to set various options, whether there are some convenient function keys designed, etc.When buying, see whether the color style of the scanner is suitable for one's own aesthetic habits. Choosing a satisfactory appearance, volume and style can well decorate the family environment.

2. Ordinary office users

If you are an ordinary office user, the purpose is very clear, that is to scan faster. Therefore, when purchasing, more attention should be paid to the scanning speed of the scanner and whether it is equipped with a paper feeder, which is conducive to the automatic continuous scanning of manuscripts. In terms of resolution, about 1200dpi can meet almost all the requirements. As for color, it is not as high as that of professional users because of the common color deviation of computer screens. In addition, the ease of use and intelligent design of the scanner are equally important to ordinary office users. Humanized design can save some complicated scanning steps, especially for users who often need batch scanning.

3. Professional users

Users who are engaged in professional image processing in graphic design, advertisement production, printing and typesetting and other fields have high-end requirements on all aspects of scanner performance, especially the scanning effect, which requires color restoration, clarity and level to be higher than that of ordinary scanners. When purchasing a scanner, in addition to paying attention to high hardware color bits and high resolution (generally above 1200dpi), you should also know another important parameter of the scanner: dynamic density (this parameter is generally less than 2.0 for ordinary scanners). The higher the dynamic density, the stronger the scanner's hierarchical performance. It is generally necessary to scan films, negatives and other transparent manuscripts. Since the storage space occupied by higher resolution scanning pictures is certain, if the scanner is equipped with a faster SCSI interface (or IEEE 1394), the data transmission time can be greatly shortened and the work efficiency can be improved. Thus the requirements for volume, weight and appearance characteristics are not important.

4. Comprehensive guidance

The restoration degree of an original image by a scanner is not only related to the above resolution, but also affected by the color depth and gray scale. The scanning speed is closely related to system configuration, scan resolution setting, scanning size, magnification, etc. Fast scanner speed is important, but the image quality cannot be affected by improving the speed. Some scanners with very fast scanning speed will lose some image information during scanning. Therefore, you must try to scan it yourself before making a formal purchase. It is best to bring along some different scanned originals, such as photos, printed images, newspaper text, etc. At the same time, you can also try to scan some objects, such as keys and cigarettes, to see if the effect is satisfactory.

Projector is used more and more widely, not only in some business occasions, but also in many people's home film systems. But most people don't care much about how to use the projector correctly.

In fact, there will be many small problems in the use of the projector. In addition to the basic installation and maintenance, there will be some puzzling occasion in the use of the projector, which will make the user misunderstand the projector. Today, I'll explain the common problems that the projector occasionally has, so that users won't be too flustered in the use process.

The first is about sound.

Many users will be confused about the sound when using the projector. The speaker of the projector is very small. The main function of the projector itself is to show the perfect picture, and the loudspeaker takes up too much internal space, so the loudspeaker design of the projector will be relatively small, so it is better to cooperate with the external sound equipment when using the projector. At present, most of the projectors on the market are equipped with sound output terminals, which is also fully prepared for the external sound equipment.

Secondly, the brightness of the projector.

Many users responded that the projection screen was not as bright as before after the projector was used for a period of time. They asked if there was a quality problem with the projector. Actually not. At present, most projector products use the built-in bulb penetration projection mode, and the projection brightness is mainly determined by the bulb, while the display brightness of the projector's bulb is inversely proportional to its use time. Generally speaking, after 120 hours of use, the brightness of the bulb will drop by 20% - 30%. Therefore, users must pay attention to protecting the projector's bulb in normal use. Do not use it for a long time. Try to turn off the projector when not in use.

Finally, the problem of the picture.

Sometimes the projector has the state that image is unstable state, or the picture blurs and shakes. This is also not a problem with the projector function. Some tips are needed to solve it. First look at the image instability.

The output image of the projector is unstable and has stripe fluctuation, which is mostly due to the inconsistency between the power signal of the signal source and the power signal of the projector. The user needs to plug the power of the projector and the signal source into the same terminal block, which can basically solve this problem.

The condition of blurred and dithering picture. Generally speaking, if the projector is too far away from the signal source, it will weaken signal, and the performance projected on the screen can be blurred or dithered. So when using the projector, it is noted that the distance between the signal source and the projector can not be too large. If the distance between the two is large, it is recommended to use a signal amplifier to help the projector receive the signal from the signal source.

Picking out the best projector can definitely become a headache for many. People usually think that going to a showroom and browsing projectors at a time can be tiring as you don’t have enough knowledge about the topic. However, you need not worry about anything. Here we present you the ten best ways to pick the right projector for you:

PICK THE PROJECTOR THAT CURBS YOUR REQUIREMENTS

To be precise, there are three kinds of projectors in the market, namely Home Theater Projectors, Business Projectors, and Pico Projectors. Home Theater Projectors usually project wider content and emphasize on image quality and high contrast as they are fit for in-home use. Business Projectors are meant for projecting ppts during Business Meetings and Conferences. On the other hand, we have Pico Projectors that are generally used for gaining portability as you can carry them wherever you go. Make a wise choice as per your requirements.

PICK THE PROJECTOR OF THE RIGHT TYPE

The three most general types of projectors are DLP projectors, LCD projectors, and LCoS projectors. DLP projectors are lightweight and are good for having a smooth projection of video content that can project fast-action scenes with ease. LCD projectors are generally brighter whereas LCoS usually cover everything.

PICK THE PROJECTOR WITH GOOD LIGHT SOURCE

Projectors typically use a standard lamp, laser, or LED for light projection. It is often recommended that you opt for LED projectors instead of ones with a standard lamp. The laser projectors are energy efficient and offer better outputs too, but still LED ones are safer for the eyes.

PICK THE PROJECTOR WITH THE PERFECT ASPECT RATIO

The aspect ratio plays a significant role in achieving the drool-worthy picture quality of a good projector. You may find a lot of attractive projectors in the market. However, very few of them manage to project good quality video content on the big screen. Even though 4:3 projectors are cheaper, 16:9 are better for high picture quality.

PICK THE PROJECTOR WITH THE RIGHT RESOLUTIONS

Yet again, the debate about getting high quality projected video content continues. The resolutions of the projector vary in accordance with the aspect ratio. For 4:3, we have SVGA (800x600) and XGA (1024x768). On the other hand, for 16:9, we have standard HD (1280x720), WXGA (1280x800), and Full HD (1920x1080). 16:9 and Full HD make up for a great combination for achieving high quality projected video content.

PICK THE PROJECTOR WITH THE GOOD BRIGHTNESS

Brightness plays a significant role in the projection of video content. A projector with good brightness can make up for a great video watching experience for the user. Remember that brighter the light, the better the color. The vibrant color won’t impress you unless they are cast in a more colorful frame. Especially for business Projectors, you must have high brightness.

PICK THE PROJECTOR WITH THE REQUIRED CONTRAST RATIO

It is the difference between the darkest and brightest areas of your projected video content. For getting better details out of your projected video content, a good projector must have a defined contrast ratio that can highlight the presence of shadows, in turn, enhancing the picture quality. You’ll know the worth of contrast ratio mostly while projecting video content in darker rooms.

PICK THE PROJECTOR WITH EXCELLENCE THROW RATIO & LENS ZOOM

Throw ratio is critical at times when you are planning to mount the projector right as it decides how much wide image is going to be cast on the screens. In such cases, short-throw projectors are the best as even if the projector is closer to the screen; a wide image will be cast on the screen. The lens zoom avails the user to adjust the size of the screen which can help you out if you have a pico projector in your vicinity.

PICK THE PROJECTOR WITH THE PRODUCTIVE CONNECTIVITY OPTIONS

You might find the need of connecting external devices to your projector now and then. In such cases, you should have the productive ports that can avail you to connect external devices to your projector. Therefore, you must confirm that the projector has important ports such as USB port, HDMI port, VGA port, SD card slot and other ports that should be present for allowing you to connect the devices you own with the projector you’re about to buy.

PICK THE PROJECTOR WITH NICE FEATURES

Features such as Keystone Correction and Lens Shift might help you a lot in enhancing your experience while using a projector. These features will help you in deciding the screen orientation and adjust the image on projectors with ease. In addition to these, you can also opt for projectors that support 3D technology as in the end having a good experience while using your projector is all that actually matters. Wireless projectors and adapters are a good option as well.

This is it for now. Have a fun time choosing the right projector for you!

DLP is the abbreviation of "DigitalLightProcessing", i.e. digital light processing. That is to say, the image signal should be processed digitally before the light is projected. It is based on the DigitalMicromirrorDevice (DMD) developed by TI (Texas Instruments) company to display the visual digital information. Specifically, DLP projection technology uses DMD as the main processing element to realize the digital optical processing.

DMD chip is an extremely accurate optical switch device. It can reflect light through micro mirror matrix and form projection, which can digitally modulate light. In DLP orthographic projection system or HDTV, red, green and blue light alternately irradiate the lenses, which are turned on or off according to the video or graphics signal fed into the bottom memory chip. Lenses are switched on and off more than thousands of times a second; the light they reflect passes through the lens and reaches the screen to produce images.

LIn projectors for high brightness applications, three DLP chips are used - green, red and blue, respectively. The light generated by the lamp will be separated into these three colors by the prism, and then directed to the corresponding DLP chip. Then, the reflections of the corresponding pixels on each DLP chip are recombined to generate the image.

The single-chip DMD system used in DLP TV, home theater and small media projector consists of a DMD chip, a light bulb, a color wheel and a projection lens. These devices can well generate sharp and colorful video and images in theaters and some large places. A 3-piece DLP system has more realistic colors and higher brightness. In a 3-chip DLP system, white light is divided into red, green and blue light through prism. These three colors correspond to one DLP chip, and the colored light reflected by each DLP chip will be mixed together to generate a pixel on the screen through the projection lens. DLP cinema system can generate more than 35 trillion colors, bringing unparalleled visual experience.

With DLP technology, commercial projectors, home theater systems, high-definition TVs and large venue projectors can provide incredibly clear and sharp images. It is a digital technology, so DLP projection system can always maintain excellent performance in the service life of the projector, thus bringing unimaginable reliability for display electronic products. Moreover, DLP technology is based on semiconductors, and its lightweight characteristics enable manufacturers to develop smaller, lighter and better products than other technologies. Portable projectors with DLP technology can currently provide 2000 lumens or higher output with a total weight of two pounds.

Do you know how to use scanners? Then, how? If you want to know the practical method, you must have a good look at the following content!

The scanner is a device that uses photoelectric technology and digital processing technology to convert graphic or image information into digital signals by scanning.

Scanners are usually used for instruments and equipment external to computers. By capturing images and converting them into digital input devices that computers can display, edit, store, and output. The scanner can be used to scan photos, text pages, drawings, art pictures, photographic negatives, film films, and even three-dimensional objects such as textiles, sign panels, printed board samples, etc. and to extract and convert original lines, graphics, text, photos, and planar objects into devices that can be edited and added to files. The scanner belongs to the input system of computer-aided design (CAD). Through computer software and computer, the interface of output equipment (laser printer, laser plotter) forms the computer processing system before screen printing. It is suitable for office automation (OA) and is widely used in sign panel, printed board, printing industry, etc.

How to use a scanner

(1) Determine the appropriate scanning mode

Scanners can be used to scan images, text, photos, etc. Different scanning objects have different scanning methods. Opening the scanner's drive interface, we found that the program provides three scanning options, of which the "black and white" method is applicable to documents in black and white. The scanner will represent black and white pixels by one bit, thus saving disk space. "Grayscale" is applicable to a mixed layout of pictures and texts with both pictures and texts，scanning this type of picture with both texts and multiple grayscale levels. "Photos" is suitable for scanning color photos. It requires multi-level sampling and storage of red, green, and blue channels. Before scanning, it is necessary to select an appropriate scanning method according to the scanned object before obtaining a higher scanning effect.

(2) Optimizing scanner resolution

The higher the scan resolution is, the clearer the image is. However, considering that if the resolution of the output device is exceeded, it is impossible to print a clearer image. It only takes up more disk space and has no practical value. Therefore, it is necessary to choose the appropriate scan resolution. For example, prepare to use a 600dpi resolution printer to output the results and scan at 600dpi. If possible, scale down large images after scanning. For example, if you scan a 4*4-inch image at 600dpi and reduce it to 2*2 inches in the editing program, its resolution is 1200dpi.

(3) Set the scanning parameters

When a scanner pre-scans an image, it scans according to the system default scanning parameter values. For different scanning objects and different scanning methods, the effect may be different. Therefore, in order to obtain higher image scanning quality, the parameters can be adjusted manually. For example, when the brightness of grayscale and color images is too bright or too dark, the brightness can be changed by dragging the slider on the brightness slide bar. If the brightness is too high, the image will look white. If the brightness is too low, it is too dark. The brightness of the image should be moderate when dragging the brightness slider. Similarly, for other parameters, local modifications can be made according to the same adjustment method until their visual effects are satisfactory. In a word, a good scanned image can meet the printing output without further adjustment in the image processing software and is closest to the printing quality..

(4) Set the file size

No matter whether the scanned object is text, image, or photo, it is an image after being output by the scanner, and the size of the image is directly related to the size of the file capacity, so the size of the file should be set during scanning. Usually, the scanner can automatically calculate the file size when previewing the original manuscript sample, but knowing how to calculate the file size is more helpful for you to make appropriate choices when managing scanning files and determining the scan resolution. The calculation formula of the binary image file is horizontal dimension x vertical dimension x (scan resolution) 2/8. The calculation formula of the color image file is horizontal dimension x vertical dimension x (scan resolution) 2×3.

At present, there are three kinds of projection technology: CRT, LCD, and DLP.

CRT projector is the earliest projection technology, which is similar to the CRT display. It has the advantages of long life, rich color display, good reducibility, and rich ability to adjust geometric distortion. Due to technical constraints, it is impossible to improve the resolution and lumen at the same time. Therefore, CRT projectors have been phased out at this stage.

The technology of LCD projector is transmission projection technology, which is the most mature at present. The color of the projection screen is restored to be true and bright. With high color saturation and high light utilization efficiency, an LCD projector has a higher brightness output. At present, the LCD projector is the main projector with a high lumen in the market. Its disadvantage is that the black layer is not very good. LCD projection technology is divided into LCD and 3LCD. The difference between them lies in the color restoration degree and picture quality.

DLP reflective projection technology. The gray level and signal-noise ratio of DLP projector image are greatly improved, and the image quality is fine and stable. In particular, when playing dynamic video, the image is more smooth, without pixel structure sense, the image is natural, and the digital image restoration is true and accurate. The advantage of DLP compared with 3lcd is that there is no crosstalk between grayscale and 3D.

Of course, there is also LCOS projection technology, which is a new projection technology. Because the cost is too high, it is seldom used

Projector contrast

Contrast is the ratio of black to white, that is, the gradient level from black to white. The larger the ratio, the more gradients from black to white, and the richer the color representation. Contrast is very important to the visual effect. Generally speaking, the larger the contrast is the clearer the image is, and the brighter the color is. However, if the contrast is small, the whole picture will be gray. High contrast is very helpful for the clarity, detail, and gray level of the image. High contrast has advantages in black-and-white contrast, clarity, integrity, and so on. Relatively speaking, in the aspect of the color level, the influence of high contrast on an image is not obvious. The contrast has a greater impact on the dynamic video display effect. Because of the fast conversion of light and dark in the dynamic image, the higher the contrast, the easier it is for the human eyes to distinguish such a conversion process. The products with high contrast have more obvious advantages in detail performance, clarity, and high-speed moving objects performance in some dark scenes.

Projector brightness

The brightness of the projector is usually expressed by light out, which describes the ability of light source radiation to produce a visual response in unit time, and its unit is the lumen. There are two methods to measure brightness. 1. The average brightness of 9 intersections of "Tian" is multiplied by the length and width of projection. Test precondition projection distance is 2.4m; the projection size is 60 inches. 2. All black and all white contrast method. Select a black-and-white contrast image, measure, and calculate the black-and-white brightness difference times the projected area. When choosing the projector to determine the brightness index, we should not only consider the size of the used space but also consider the influence of the use of environment brightness. And the brightness selection should leave a margin, and the brightness will decrease after a period of use due to the influence of the bulb. It is recommended to choose 800-2000 lumens for the brightness of the home projector, 2000-4500 lumens for a small conference room or standard classroom, 3500-5000 lumens for medium conference room, and ladder classroom, and 5000 lumens for large conference room or auditorium. Of course, this is only a reference value. The accurate brightness should be calculated according to the actual ambient brightness and the size of the screen. For example, taking the classroom as an example, the average brightness is 500lux, and the formula is projector brightness = ambient brightness * 2 (Times) × screen length * screen width * 1.2 (loss coefficient) ≈ 3300. Therefore, it is necessary to fully consider the use environment and cost performance to select the appropriate brightness index.

Projector lens

Zoom ratio: the ratio of the maximum focal length to the minimum focal length, that is, the zoom ratio of the projection picture under a certain projection distance. This parameter does not affect the projection distance, etc.

Projection ratio: projection distance / screen width.

Lens focal length: distance from LCD panel to lens, unit: mm

Projection distance: distance from lens to screen, unit: mm

Panel size: LCD size in inches

Screen width: the effective width of the screen, in inches. It should be noted that the aspect ratio should be the same as that of the panel.

Calculate the projection distance according to the projector: projection distance = screen width * lens focal length/panel size

Projection distance = screen width (mm) × projection ratio

Calculate the appropriate projector according to the site conditions: lens focal length = projection distance * panel size/screen width

Precautions for projector installation:

1. Accurately calculate the projection distance, which is the distance between the lens and the screen; align the projector lens with the left and right center of the screen as much as possible; calculate the installation height of the projector according to the difference between the lens and the screen height (refer to the projector manual). Special attention shall be paid to this item when using a fixed focus projector, so as to avoid that the image cannot be full screen or over the screen. In case of slight error, fine adjustment can be made through the relative position between the projector and hanger.

2. During construction, pay attention to load-bearing reinforcement for the installation position of the projector and curtain according to the actual situation on site.

3. Try to select the projector hanger with excellent quality. The poor hanger is not perpendicular to the roof, and the installation screws cannot be tightened. Such problems affect construction efficiency.

4. If the electric screen is selected, a strong electric socket shall be reserved in the screen box, and the electric screen shall be equipped with remote control as far as possible to avoid affecting the appearance.

5. Do not power off the projector immediately after debugging. After the bulb cools and the fan stops rotating, cut off the power.

6. For projector cable, VGA, HDMI, and other cables can be reserved according to specific requirements, and network cable can be reserved according to specific functions of the projector.

(5) Store curves and load scanning software

Sometimes, in order to get the best color and scanning contrast, take a low-resolution scan first, open it in Photoshop then, and use Photoshop's curve function to improve color and contrast. Save the curve and load it back into the scanning software. The scanner will now use this color correction curve to create a better high-resolution file. If several images are scanned with a similar gamut range, the same curves can be used, and curves can also be stored frequently and loaded back as needed.

(6) Place the scanned object according to the required effect

In the actual process of using images, it is sometimes hoped that images with oblique effects can be obtained. Many designers often input images into computers through scanners, and then use professional image software to rotate the images to achieve the rotation effect. However, this process is very time-consuming, and the image quality will decline according to the angle of rotation. If you know in advance how the image is placed on the page, then using the protractor and the bottom edge of the original to place the original at a precise angle on the cylinder and the platen, you will get the highest quality image without rotating in the image processing software.

(7) Find the best scanning area on the glass plate

In order to obtain the best image scanning quality, find the best scanning area of the scanner, and then place the object to be scanned here to obtain the best and most fidelity image effect. The specific searching steps are as follows: first, set all controls of the scanner to automatic or silent state, select all areas, and then scan a blank, white or opaque sample with low resolution; then use Photoshop, a professional image processing software, to open the sample manuscript. Use the averaging command (Equalize menu item) in the software to process the sample manuscript. After processing, you can see where there are cracks, stripes and black spots on the scanner. You can print this document and cut out the best area (that is, the most stable area) to help place the image.

(8) Use transparent sheet fittings to obtain the best scanning effect

Many flatbed scanners are equipped with transparency fittings placed at the top of the scanner bed. In order to obtain the best scanning of transparent films or slides, remove the pictures from the rack and slide mounting rack and mount them on the glass scanning bed with the reverse side facing down (the reverse side is usually a rough surface). Cut out the mask with black paper and cover the entire scanning bed except where the manuscript is set. This will reduce glare and overexposure during scanning. Similarly, when scanning a three-dimensional object, cover the cover of the scanner with an object with a strong contrast in color with the object you are scanning. This will help you to select it more easily with the PhotoshopColorRange tool.

(9) Maximize that color gamut of the scanned image

In order to make full use of the 30-bit or 36-bit scanner to increase the color range, the scanner software (such as FotoTune of Agfa) or other company's software should be used to adjust the color as much as possible. Because Photoshop software is limited to 24-bit images, images may be inserted in the widest color gamut range.

(10) Scan printed matter with no screen printing technology

When scanning printed matter, there will be screen flowers in the continuous tone of the image. If the scanner does not have a screen removal function, try to find the resolution that minimizes the screen size. Often, the same or double resolution of the screen line of printed matter may work. Once you get a fairly good scan, use Photoshop as a Gaussian Blur filter (with a setting of less than 1 pixel) to slightly soften the mesh until you cannot see it. Then use Unsharp Mask to sharpen the image back. Scanning can also be improved by slightly rotating the image because the continuously adjusted screen angle is changed. For black-and-white images, the rotation of 45 degrees is just right. For CMYK images, experiments will be required.

The book scanner is a kind of computer input equipment that can input image data into the computer. Pictures, photos, films, drawings and all kinds of documents can be input into the computer by the scanner and stored in the form of pictures. Some people vividly call Book scanners "the eyes of computers". Document management is the most widely used field of scanners.

The book scanners can also cooperate with optical character recognition software OCR (optical character recognition) to convert scanned documents into computer text form. It omits a lot of manual input time.

The concept of scanner resolution: scanner resolution is divided into optical resolution and maximum resolution. The maximum resolution is equivalent to the interpolation resolution and does not represent the true resolution of the scanner. Therefore, when we purchase scanners, we should take the optical resolution as the judgment standard.

The resolution unit of the scanner is DPI. The maximum optical resolution of the scanner is multiplied by two numbers, such as 600 × 1200 DPI (also known as 600 × 1200 line). The former number represents the lateral resolution of the scanner, i.e. optical resolution, which is determined by the CCD performance of the scanner. The latter number represents the vertical or mechanical resolution of the scanner, which is the resolution of the stepper motor used by the scanner. When judging the optical resolution of the scanner, we should take the smallest one as the criterion.

Resolution is the main technical index of the scanner. It represents the ability of the scanner to show the details of the image, which determines the fineness of the image recorded by the scanner. The higher the resolution of scanning, the higher the quality of the scanning image, but there are limits. When the resolution is greater than a certain value, it will only make the image file larger and not easy to process, and it will not significantly improve the image quality.

In practice, the higher the resolution setting, the larger the scanned file, and the slower the scanning speed, which is not convenient for management and saving. Therefore, we seldom use the highest resolution of the scanner in actual scanning. We need to use different resolutions according to the nature of the document. The general settings are as follows:

1. In the category of photos, the reso lution of 350-400 is adopted, some of which are particularly important, and even the resolution of 600 or higher can be adopted.
2. Detection report, business license, code certificate, etc., with 300 resolution.
3. Some important documents (such as archives, files, ancient books, books, etc.) adopt 300 resolution.
4. The resolution of 300 shall be adopted for engineering visa documents.
5. General contract text, text records, etc., with a resolution of 150 to 200.

Therefore, when choosing a scanner, the scanner with 600 resolution has fully met the requirements, because in general, we can use up to 300-400 resolution. Use 600 resolution in special cases.

When the book scanner is in use, the scanning range can be adjusted by dragging the mouse, and the resolution can be set according to the needs, so the operation is very simple.

Our high quality movie projector adopts advanced technologies and modern design. The following types of smart movie projector are what we offer currently. You can click each page for detailed information. If you have any other questions about our movie quality projector, please email us. We will reply to you as soon as possible.

When we come into contact with the scanner, we will see various technical indicators. The following is a brief introduction to common indicators.

Technical specifications of scanner

1. Scanning accuracy. Resolution, as we often say, is an important parameter to measure the level of a scanner. It reflects the fineness that a scanner can achieve when scanning. Scanning accuracy is usually expressed in DPI (resolution). Similar to the technical specifications of ink-jet printers, the larger the DPI value, the finer the image scanned by the scanner. Scan resolution is divided into two types: optical resolution (real resolution) and interpolation resolution (maximum resolution). The former is in the form of hardware and the latter is in the form of software.

2. Number of color bits. The number of color digits indicates the scanner's ability to recognize colors and the range of colors it can describe. It determines the true degree of color restoration. The larger the number of color digits are, the better and more realistic the scanning effect will be, and the less distortion in the scanning process will be.
3. Gray level. The gray level of the scanner reflects the ability to provide a range of levels from dark to light during scanning, specifically the ability of the scanner to smoothly transition from pure black to pure white. The larger the number of grayscale bits is, the richer the level of scanning results are and the better the effect is.

4. Scan the format. It refers to the range that the scanner can scan, that is, the size of the paper, generally A4, A4+, A3, etc.
5. Compatibility. Almost all scanners can be used for Windows PC.

6. System environment. Scanner work requires drivers, which work in a certain systems, such as WIN98, WIN2000, WINNT, etc. in addition, some SCSI and USB scanners also have drivers working in FOR MAC (apple) OS.
7. Optional accessories. Usually, they refer to the paper feeder (ADF) and through scan adapter (TMA). Not all scanners support additional accessories. As mentioned earlier, some scanners have TMA.

Scanning software

1. Image software. Scanning objects are used for image processing, such as PHOTOSHOP, self-image, scanning masters, and image programs built into WINDOWS.

2. OCR software. Scanned objects are used for word processing, image files are converted into text files, such as Thunis OCR, Shangshu OCR, Meng Tian OCR, Wen Tong OCR, etc., as well as TEXTBRIDGE used for English recognition.
3. Vectorization software. For professional scanning of drawings, it is generally necessary to cooperate with engineering scanners which almost all scanners do not have. They need to be purchased separately.

Scanning principle

At present, scanners on the market adopt two completely different manufacturing principles. One is CCD technology, which uses a lens to image on a photosensitive element. The other is CIS contact scanning. CIS technology used to be mainly used in fax machine manufacturing. Its image will be directly recorded by CID photosensitive element after being scanned by LED lamp tube without lens refraction, so the whole body can be made very thin and light. It is more suitable for scanning documents or general plane pictures and texts, but not for scanning three-dimensional articles or transmission documents (Note: transmission documents are documents through which light can pass, such as negatives, slides, etc.).

What does the contrast of projector mean, should it be high or low, how much is appropriate? In fact, the contrast ratio of projectors has little effect on the picture performance, so you don't need to pay special attention to the contrast value when buying projectors. However, in case you are still confused in this respect, continue reading!

What is the projector contrast

Contrast is the most important indicator of the image quality of the projection system. It describes the comparison of the brightest and darkest light output on the screen, but it is easily affected by ambient light. For example, in a good movie theater, the best contrast can be seen, while in some exhibitions, the contrast of the image will be affected due to the "scouring" of light.

Projector contrast is the ratio of black to white, that is, the gradation from black to white. The larger the ratio is, the more gradation levels from black to white are, thus the richer the color expression is. Generally speaking, the greater the contrast is, the clearer and more striking the image is, and the brighter and more gorgeous the color is. However, if the contrast is small, the whole picture will be gray.

How much contrast is appropriate for the projector

At present, the nominal contrast of most LCD projector products is around 400:1(ANSI), while the nominal contrast of most DLP projectors is above 1500:1 (all white/all black). Nowadays, many new projectors with the high contrast of tens of thousands, which are actually false numbers.

From a professional point of view, the difference between 1000:1 and 10000: 1 is basically invisible. From a non-professional point of view, the difference between 2000:1 and 3000:1 is virtually the same. Both 1000:1 and 10000: 1 are difficult to measure with instruments.

Nowadays, the original contrast of projection products is actually fixed at a level, and the difference between various products is not very large. A good projector, especially a household projector, besides maintaining the average contrast, brightness, color temperature, resolution, and grayscale are more important, and the contrast has little influence on the picture performance. So now you don't need to pay special attention to the contrast value when buying projectors.

So now you don't need to pay special attention to the contrast value when buying projectors.

As time went by, projector contrast technology has changed and the concept of dynamic contrast has emerged. What is the dynamic contrast?

What is dynamic contrast

The concept of dynamic contrast comes from liquid crystal display technology. Its core idea is to control the light output by adjusting the backlight intensity of flat liquid crystal or adjusting the pupil size of the liquid crystal projector to achieve the effect of dynamic contrast change.

When the projector works, the product counts the brightness information of each image in real-time and determines the enlargement or reduction of the pupil based on the above statistical information. The larger the pupil is, the greater the light output and the higher the brightness is. The smaller the pupil is, the smaller the light output, and the lower the brightness is. In a dark scene, the difference between the minimum brightness and the maximum brightness of the original image is small, that is, the dynamic range of brightness is narrow. In this case, by narrowing the pupil and amplifying the original signal, not only can the light projected onto the screen be effectively controlled, but also the dynamic range of data processing can be expanded, the contrast can be improved and the dark field noise can be reduced at the same time, thus obtaining more prominent black performance.

The effect of dynamic contrast

Dynamic contrast is mainly applied to projectors (dynamic aperture control) and liquid crystal televisions to reduce the black brightness in dim scenes or increase the maximum brightness in scenes, thus improving visual enjoyment. In the high dynamic contrast mode, the film application benefits the most, and the effect of clearer black and white can make it easier for us to distinguish the detailed contrast of the film.

There's only one reason to buy a projector. It's the immersive feeling that a huge screen can bring. Whether you are watching a movie or playing a game, this feeling can't be provided by TV.

With simple settings, you can create almost the same visual experience at home as you would feel in a movie theater. In a private space, whether it's just yourself, with a loved one, or with three or five friends, it's more relaxing and pleasant than in a movie theater.

Why buy a projection? Features of TV: long life, clear picture quality, brightness not affected by external brightness. It's also simple to choose a projection, which is the reason why you go to the cinema. Projection can easily display 100 inches, 120 inches or even higher screen size. Compared with TV, 80 inch TV, regardless of the price, move it home is a big problem.

Advantages of projector vs large size TV

Multifunction

Projector, together with computer, iPad and mobile phone, can form a mobile home e-learning center, especially for families with children, which is very interesting and practical. Many American families will put the projector in their children's playroom or bedroom, and put pictures and cartoons. If the wall or curtain area is large, the children will feel very immersive.

Eye protection

The projector mainly relies on the principle of diffuse reflection. The light is softer. Compared with traditional TV, it has less stimulation to the eyes and is not easy to cause visual fatigue.

7 standards for purchasing a projector

1. Black position ability: it directly determines the contrast of the projector and has a direct impact on the color saturation. Therefore, when choosing a projector, we should pay attention to the performance of the black part of the screen in the process of projection: it should not be replaced by dark gray, nor be huddled together. There should small details.

2. Projector resolution: generally, 720p resolution projectors and 1080p resolution projectors are suitable for use at home.

3. Service life: the service life of the projector is generally about four years. The light bulb may be broken in a year or two. It needs to be renewed before it can be used again. So when choosing a projector, we should also check its warranty period and after-sales service.

4. Lumen: lumen determines whether you can see the video in the daytime or white light. If it's not in the daytime, or when the lights are on, it's enough to choose a lumen between 800 and 2000.

5. Contrast: contrast determines the color level of the screen, and is the key to see more details of the screen. So, when choosing a projector, choose the product with the highest contrast within your budget.

6. Noise: if it's noisy, you will feel disturbing after taking it home. Generally speaking, products with noise below 40dB are acceptable.

7. Projection screen: the projector can cast a better effect on a white wall, but for a better viewing effect, it is recommended to buy the projection screen. According to the different production processes and surface coating, the projection screen is generally divided into ordinary white screen and glass bead screen.

Commercial projector or home projector

Commercial projectors and home projectors are quite different in terms of parameters and performance.

The resolution of commercial projectors is not very high, they are 720p or lower, and the ratio is usually 4:3. The brightness is much higher than that of ordinary household projection, which can reach more than 3000 lumens, and the lights are used without pressure during the day; the color reduction and contrast will be slightly worse than that of household projection.

In terms of home projectors, pay more attention to resolution. 720p and 1080p are mainstream. Of course, the trend must be 4K. In terms of the one of Brightness in 1000 - 2000 lumens, pay more attention to color and contrast performance.

Main factors determining the price of the projector:

Size of projection chip;

The size and complexity (chip size directly determines. The larger the chip, the higher the cost; of the machine (the entire optical path)

The size, structure, and material of lens and other peripheral areas (indirectly related to chip size).

Basically, there is only one chip size that determines the cost of projection. Different chip sizes determine the purpose of the projector and limit the final effect. So when choosing a projector, please focus on the size of new products.

Mechanical aspect: strictly prevent strong collision, extrusion and vibration. The strong shock can cause the displacement of the liquid crystal, affect the convergence of the three LCDs during the projection, and the RGB color does not coincide. The lens and mirror in the optical system will also deform or damage, affecting the image quality. Under the impact of the zoom lens, the track will be damaged, causing the lens to be stuck, or even the lens can not be used.

Optical system: pay attention to the dust prevention and ventilation of the use environment. At present, the LCD and DLP optical mechanical systems we use are very small, some are only 0.9 inch, and the resolution has reached 1024x768 or even 1290x1080, that is to say, each pixel is only 0.02mm, and the dust particles are enough to block it. Due to the heat dissipation of the projector's light panel, there is usually a special fan to cool it with the flow of dozens of liters of air per minute. After passing through the dust filter net, the high-speed air flow may also contain small dust particles, so dust is one of the biggest enemies of the projector.

Ten precautions in the use of projector:

1. Try to use the original cable and wire of projector
2. Keep away from water or damp place when using the projector
3. Pay attention to dust prevention, and take dust prevention measures after consulting professionals
4. Keep the projector away from heat source
5. Pay attention to the nominal value of power supply voltage, ground wire and power polarity of the machine
6. The user is not allowed to repair and open the machine body, and the original accessories shall be used as much as possible when replacing the internal cable parts
7. When the projector is not in use, the power must be cut off
8. When the projector is in use, if any abnormality is found, unplug the power supply first
9. Pay attention to cooling the projector after use

Read your own projector

On the body of the projector, there are indicator lights. One of the indicators is marked "TEMP", which is the projector bulb indicator. During use, the "TEMP" indicator turns red, indicating that the projector is overheated, and when it is green, indicating that the temperature is normal. The "LAMP" indicator light turns red, which may be that the bulb is overheated. In this case, stop the machine. After the fan stops running, turn off the power to cool it, and check the ventilation and heat dissipation.

Some of the more advanced models have the function of overheat protection. When the red light is on, it will shut down automatically. If the ventilation and heat dissipation are good, wait for the projector to cool down fully (about 20 minutes), and then turn it on for use. If "LAMP" indicator lights up again soon after the restart, it may be that the bulb is aging, so further check the bulb.

In daily life and office, still many people do not know the difference between a high-speed camera and a scanner, which is better? What is the difference between a high-speed camera and a traditional scanner?

1. Comparison of the appearance of the high-speed camera and scanner

High-speed camera: Most high-speed cameras are designed to be portable, easy to carry, and overall look smaller, so they will not occupy too much position in daily life and office.

X9 portable scanner in use

Scanner: Traditional scanners are bulky, need to occupy a large position and are difficult to carry.

2. Comparison of the functions of the high-speed camera and scanner

High-speed camera:

1. Take iCODIS high-speed camera as an example. The high-speed camera can scan rapidly for one second, and the scanning effect is sufficient for office and living needs;
2. Can scan three-dimensional objects, 3D objects, etc.; OCR recognition is supported. The scanned content can be converted into editable WORD documents and PDF files can be produced with one click;
3. Can flatten the curved surface, and can directly flatten the bent parts of books and materials;
4. Support secondary development of SDK, customized according to different professional requirements of enterprises or individuals, such as adding multiple functions like face recognition camera, second-generation ID card reader, fingerprint collector, IC card recognizer, microphone, etc;
5. Customize canned pictures with signature functions such as watermarking or adding electronic signatures. Scanned electronic documents can be directly classified to facilitate staff to store or search;
6. iCODIS high-speed camera is easy to operate. All functions can be completed with only a click of the mouse. Meanwhile, USB direct-connected computer settings are adopted with convenience and simplicity.

Scanner:

1. The scanner uses a closed light source to shoot, which can directly avoid the influence of strong light, while the high-speed camera is easily affected by strong light;
2. The scanner's shooting effect is clearer and the imaging effect is better than that of the high-speed camera, but the size of the picture taken is also much larger than that of the high-speed camera;
3. The traditional scanner can't shoot 3D objects and other physical objects;
4. The scanner does not have secondary development function, and cannot add expansion functions such as ID card reader like iCODIS high-speed camera;
5. Scanner operation is complex, which requires operating many times to get familiar with it;

3. Price comparison between high-speed camera and scanner.

High-speed camera: iCODIS high-speed camera has high-cost performance, and the high-speed camera with different prices has different pixels, different functions, and different performances. For example, the high-speed camera with 16 million pixels, face recognition camera, second-generation ID card reader, fingerprint collector, and other functions is also far cheaper than the scanner.

Scanner:

Scanners are expensive, ranging from a few thousand to tens of thousands in size. Looking at the price alone, scanners cost a lot more than high-speed cameras.

4. Application field of high-speed camera and scanner

In modern society, be they enterprises, institutions, or government departments, they produce a large number of documents every day. What is more important is that most of the documents and materials must be kept for a long time, some even permanently, according to various regulations. Many of them have numerous documents and archives. If you want to use a conventional scanner, the workload and the required time are too much. If you use the iCODIS high-speed camera, you won't have this kind of trouble. One-second fast scanning, electronic document scanning, storage, and classification can solve this problem.

high speed camera and scanner

In the case of much scanning work, it is better to choose a high-speed camera. And it is also more economical than a high-speed scanner, but the imaging effect of the high-speed camera is worse than that of the high-speed scanner, but now the pixels of the high-speed camera is getting higher and higher, and this disadvantage is slowly fading, so more and more users have chosen an economical and applicable iCODIS high-speed camera.

The high-speed camera has been widely used in financial, insurance, securities, telecommunications, social security, public security, civil affairs, e-government, and other business windows. It is a new type of business window scanning equipment. iCODIS high-speed camera has high-cost performance and powerful functions.

Scanners are expensive, but the scanner effect is very clear. For enterprises that must have high-definition images, scanners are essential. However, if they only meet the needs of work and want to realize paperless office, iCODIS high-speed camera is the most valid choice!

Scanner performance parameters

When choosing a scanner, first look at the performance parameters, including scanning width (size), optical resolution (mostly positioned at 600x1200 dpi and higher), a color digit (the higher the digit is, the richer the color is), and photosensitive elements (CCD technology is currently the most mature one, with superior performance, while CIS is suitable for a mobile office environment).

Scanner software

Users who are unfamiliar with graphic processing can choose a scanner provided with simple operation. It is difficult to master the operation due to improper selection. It is better to provide more detailed instructions in Chinese. The selection of OCR software is very important for office users, and attention should be paid to whether they can recognize various printed handwriting, forms, the mixed arrangement of Chinese and English, etc.

Scanner interface

Common interfaces include SCSI interface, EPP interface, and USB interface (USB1.1 and 2.0), firewire (1394). It is recommended to purchase the USB2.0 interface, which is fast, supports plug and play, and is very convenient to connect with computers.

Scanner machine inspection

First look at the appearance, and then carry out detection, including checking the scanner's adaptability to paper, photosensitive elements, transmission mechanism, gray level, color, and OCR character recognition input detection.

Brand selection of scanner

The scanner should be of good quality and durability. The scanner of iCODIS not only has guaranteed quality but also has perfect after-sales service.

This is too easy to understand because LED is expensive! The 100-inch Sony TV has already sold for 500,000 yuan! At present, with the increase in LED size, the price has doubled. If the LED is put into cinemas and made into a length of more than 10 meters, the cost is unimaginable. If the LED screen is damaged, artificially damaged, etc., these will cost an arm and a leg.

Using a projector is usually called watching a movie, will using an LED screen watching TV. What if consumers complain about paying for movie tickets but watching TV?

In fact, it mainly attributes to cost, portability, and image quality. The fineness of images displayed on LED screens cannot equal with that of projectors, especially when digital projectors now have technically up to 2048*1080p resolution and can easily achieve high-definition effects.

At present, projection is the most eye-friendly one. Objects in nature, which we usually see, do not emit light themselves. Only when natural light is reflected in the objects can we see them. If it is dark, nothing is visible. LED, working on self-illumination, is anti-human and is not good for eyes. Projection is to project light onto screen cloth. When we look at projection cloth, it does not emit light. Just like looking at objects in nature, it can give people a more real feeling. The reason why reading on kindle will not make eyes easily tired is that ink screen is not a self-luminous but a reflective screen. In the same way, LED cinema does more harm than benefit. Blinding your eyes in order to watch a movie, it’s more than worth it!

Theater T700 projector is 1080p in native resolution

Resolution: For small-pitch LED, higher pixels per inch means that the difficulty of stability design increases geometrically, pixel pitch decreases by 50%, and backplane density increases by 4 times, so the resolution of small-pitch LED is difficult to further improve. At present, cinemas have basically reached 2K level, so small spacing LED still cannot meet the standards of cinemas in terms of picture definition.

At the same time, in addition to poor heat dissipation, LED display screens are also prone to some problems, such as "bad spots". At present, most of the LED screens seen have bad spots more or less. If maintenance is not carried out in time, diffusion will be formed, which will affect other normal bright spots and eventually lead to an abnormal display of some or all of the display screens. Compared with the easy-to-care screen, the maintenance cost of the LED screen cannot be ignored.

In fact, that piece of cloth in the cinema is quite expensive, so is the projector. Items like 3D, laser, etc. are quite expensive. In fact, many LED screens can be assembled on the spot, and the size is not limited. Pieces of LED screens are assembled one by one, and the cost is not too high. Why are they not used in cinemas, mainly because the existing machines in cinemas still work well? New machines will increase costs. The other reasons are inertia and conformity.
