Fang Yuanhui Book Scanner: Speed ​​determines success or failure, why do you say this? Most of the book scanners on the market now scan very slowly, and it takes a few minutes to scan a page, which is a waste of time. The factor that determines the speed is the way of scanning. Now the market is divided into matrix ccd technology and linear ccd technology. The matrix ccd technology scan speed only takes 0.3 seconds, and linear ccd scanning requires a very dazzling light to scan from scratch to After the completion of one page, the scan is completed, which is not conducive to the eyes and slow.
The matrix CCD technology is not only superior in speed to the linear CCD, but also superior in the image processing of the scanned results. The CCD technology was developed by the Bell Research Laboratory in the United States in 1969, and the earliest CCD design It is linearly arranged and the image quality is poor. In the 1980s, although CCD image sensors were flawed, high-resolution and high-quality CCDs were produced in the second half of the 1980s due to continuous research and difficulties.
1. Small-area matrix CCD: A frame needs to be scanned multiple times for software stitching. The error rate is high, and it is generally used in low-end book scanner products, such as the ps7000 and ps5000 series that Japan Konica failed to reach.
2, RGB monochrome matrix CCD: scanning color files need to be scanned multiple times to complete. Scanning speed is slow, generally used in low-end matrix book scanners, such as the French i2s book scanner.
3, full-width true color matrix CCD: full color point-to-point scanning technology, perfect image restoration. The scanning speed is fast, the color scanning takes only 0.3 seconds, and the full color processor is relatively expensive, and is generally applied to high-end non-contact scanning devices. For example, the German book2net book roll scanner series and the fully automatic book scanner kabis. With an hourly scan speed of up to 3,300 pages, the kabis robot is a world-class device.
