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

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.

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 dev...

(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...

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.

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 ...

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.

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 descr...

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.

High-speed camera scanner is a hot office product in recent years. It not only can be used for photographing, video recording, photocopying and faxing, but also has a smaller size, convenient to carry and more perfect in function compared with traditional scanners. It can be said to be a perfect solution to make the office easier, faster, and environmentally friendly. ...
