Description
technical field [0001] The invention relates to the technical field of scanner hardware systems, in particular to a dual-USB transmission system for flatbed scanners. Background technique [0002] Flatbed scanners are widely used in many fields and are important opto-mechanical-electrical integration equipment. The work of the flatbed scanner is mainly to convert the optical signal of the image into an analog signal, and then convert it into a digital signal that the computer can recognize. After the appearance of CCD image sensor and CMOS image sensor, the scanning image acquisition equipment can be electronicized and digitized. With the development of electronic computer technology, digital image acquisition and processing technology has developed rapidly, and the resolution, acquisition speed, integration degree, and reliability have all been greatly improved. [0003] According to the image sensor, scanners can be divided into CIS scanners and CCD scanners. CIS is a n...
