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 is a high-speed camera scanner? A high-speed camera is a kind of equipment used in educational institutions, which can be used for preparing lessons. A high-speed camera is a piece of ultra-portable office equipment, which belongs to low-carbon office equipment. The high-speed camera can be used to scan characters and images and can convert pictures and texts. The camera can also take photos and copy documents. Do you know what's the difference between a high-speed camera and a scanner? Which is better, a high-speed camera or a scanner?

Introduction of high-speed camera and scanner

The high-speed camera is a folding type of high-speed scanning equipment. It can recognize characters, convert pictures and texts, edit word documents, copy, take photos, and record videos. It has many functions. The scanner is a kind of equipment that uses photoelectric technology and digital processing technology. It can only carry out the graphic conversion, and it is a kind of equipment that can only use digital signals. Scanners are classified into drum scanners, portable scanners, and flat scanners. Scanners are bulky and cannot be carried around. The speed of operation is not as fast as that of the high-speed camera. Generally speaking, the high-speed camera is a multifunctional scanner.

The high-speed camera is a very mini scanning device, which can scan a variety of information and has rich functions. Many people do not know what is the difference between a high-speed camera and a scanner, and the two are obviously different in size. The high-speed camera is a kind of ultra-light equipment that can be carried around, while the scanner can only be fixed in a certain place and is not suitable for movement. I believe many people who went to school have seen a high-speed camera, which is generally used to scan teaching contents and belongs to teaching equipment.

The difference between a high-speed camera and a scanner

1. Size: Compared with scanners, high-speed cameras are small and portable, and some models can be carried around.
2. Speed: Scanners generally need to be warmed up, while high-speed cameras do not, so scanning speed is faster.
3. Some differences in functions

（1）The camera can recognize OCR characters；

（2）SDK secondary development package for high-speed camera；

（3）Automatic edge searching can be carried out during scanning；

（4）The image merging function combines two pictures together；

（5）Removing the ash can keep the document clean and tidy；

（6）PDF conversion；

（7）Customizable picture watermarking.

Which is better, a high-speed camera or a scanner?

Traditional scanners are generally bulky and inconvenient to carry. In the process of use, the scanning operation is inconvenient or the scanning speed is slow due to different situations such as file size, paper thickness, etc. Moreover, the traditional scanner can only scan flat files and cannot scan solid objects. The high-speed camera breaks through the limitation of traditional scanning, combines the purposes of copying, projection, scanning, photographing, fax, mail, and the like, has faster scanning speed than the traditional scanner, can be folded, and is convenient to carry. A single machine can handle all kinds of daily and commercial affairs and improve efficiency.

As a high-tech product integrating photoelectricity and machinery, the scanner has become a necessary electrical appliance for daily office and life due to its unique digital "image" acquisition capability, low price, and excellent performance. Scanners can be divided into platform type/flat plate type, drum type, portable type, high speed camera scanner, business card scanner, etc. There are certain requirements for their purchase, use, installation, sharing, and maintenance, and some common faults need to be handled in time. The following is an introduction to the usage, classification, advantages, and disadvantages of scanners.

Introduction to scanner

The scanner is a kind of computer external instrument equipment, which can display, edit, store, and output digital input equipment by capturing images and converting them into computers. The principle of the scanner is to use photoelectric technology and digital processing technology to convert graphics or image information into digital signals by scanning.

Purpose of scanner

A scanner can 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. to extract and convert original lines, graphics, text, photos, and planar objects into editable and added files. Scanners are suitable for office automation (OA) and are widely used in signage panels, printed boards, printing industries, etc.

(1) Fine arts and pictures can be organized in documents;

(2) Scan and input the printed text into the word processing software, thus avoid the trouble of typing again;

(3) The printed plate and panel label samples can be scanned and entered into the computer, and the wiring diagram of the plate can be designed and copied, thus solving the problem of plate making and improving the plate making efficiency;

(4) Automatic input and editing of PCB sketches, automatic input of Chinese character panels and complex icons, and modification of pictures can be realized;

(5) Adding images to multimedia products;

(6) Integrate visual information in the literature to enable it to exchange and communicate more effectively.
