According to different installation methods, the projector can be divided into table type front projection, ceiling front projection, table type rear projection, and ceiling rear projection. Portable projectors that are convenient to use anytime, anywhere are generally desk-type front projection. This projection method is greatly affected by ambient light. However, if the ceiling is designed as a front projection method during decoration, it not only has an advantage in terms of cost performa...

A scanner is a device that can scan, analyze, and convert images of photos, printed documents, and handwritten documents, or small objects such as ornaments into digital images.

Most scanners are now variants of desktop scanners. Hand-held scanners were once popular; however, because it fails to obtain ideal image quality, it has now been eliminated. These scanners all use charge-coupled devices as image sensors, while drum scanners use photomultiplier tubes as image sensors. Scanners a...

Scanner is an image capture device, which can convert the image of paper text into a digital format that the computer can display, edit, store and output, such as JPEG, JPG, TIFF, MTIFF, or PDF. Scanners have a wide range of applications, for instance, scanning and combining art graphics and photos into files, scanning and inputting the printed words into the word processing software to avoid re-typing, scanning and inputting fax file into database software or word processing software for sto...

Portable scanners generally refer to high-speed scanners or high-definition cameras plus OCR text recognition software. It mainly uses scanning (shooting) to image the scanned (shooting) medium, generally in a picture format. At this time, OCR recognition technology can be applied. The scanned high-definition image plus OCR recognition technology can convert the image into text information, and strip the text from the picture. In general, portable scanners are managed through their own matchi...

Before the projector appeared, we mainly used slide projectors. In fact, current projectors are also special slide projectors. Some scholars have shown that the development of projectors, animation, and movies are inseparable. The earliest use of light and shadow technology began in the 17th century with the "magic slide" invented by a Jesuit priest named Atanas Kosher. Later, it has become a toy and its modern name is the projector. At first, this technique was mainly used for entertainment....

There are different types of projectors, such as CRT, LCD, DLP,  depending on their working...

(1) 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 scan...

In recent years, scanners have become an important part of families and offices. Scanner technology is ubiquitous and used in a variety of ways. A flat-plate scanner, also known as a desktop scanner, is the most functional and commonly used scanner. Let's learn how the scanner works together.

Working principle of scanner - introduction

As the third generation of computer input equipment after keyboard and mouse, the scanner is a high-precision photoelectr...

1. PERFORMANCE PARAMETERS

① Scanning format: Scanning format usually has specifications such as A4, A3, A3+. Large-format scanners are more expensive. Generally, it's better for office users to use A4 format scanner than the A3 page scanner.

② Optical resolution: It reflects the clarity of the scanned image. The higher the resolution, the sharper the ...
