基于USB接口的彩色扫描仪的优化设计

Optimized design of color scanner based on USB interface

扫描仪作为一种高科技产品,被誉为计算机的“眼睛”。介绍了扫描仪的产品分类,重点阐述了一种基于USB接口的单片彩色扫描仪的工作原理及电路设计,为实现彩色扫描仪的优化设计创造了条件。

The scanner, as a high-technology product, is regarded as the computer＇s “eyes”. This paper introduces the classification of scanners, and then expresses the operation fundamental and the circuit design of a single chip color scanner that is based on USB interface, which provided the conditions for realizing optimized design of the color scanner.
