Problems solved by technology

[0004] With the improvement of scanning quality, the capacity occupied by image information is also increasing, and the transmission time is also getting longer and longer. Simply increasing the buffer capacity of the scanner is difficult to improve the high-quality scanning efficiency of the scanner, which seriously affects The scanning efficiency and image quality are improved; in the image acquisition and processing of the scanner, the image acquisition is designed and analyzed through experiments. The moving speed of the CIS sensor during the scanning process, the color and intensity of the LED light of the CIS and the subsequent signal conversion have a significant impact on the optical scanning. The impact of quality is relatively large, so the control and acquisition part of the motor used to drive the CIS sensor has become particularly critical, but the drive control and acquisition end of the motor on the market are not optimized enough, which indirectly affects the scanning of the CIS scanner quality

Abstract

The invention relates to the technical field of scanner systems, in particular to a flat scanner system. A main chip MCU is electrically connected with a USB interface module, a motor driving module and an AD sampling module; a data conversion chip comprises a USB1 pin and a USB2 pin which are electrically connected with the main chip MCU; a buffer is electrically connected with a USB differentialdevice and the data conversion chip at the same time; the model of the data conversion chip is an FT2232H or Cypress chip, and the model of the main chip MCU is STM32F103ZET6. A USB1 pin unit and a USB2 pin unit of the data conversion chip are electrically connected with a data transmission pin unit of the main chip MCU. The scanning efficiency is improved through two paths of USB alternate transmission, the motor driving circuit with more accurate control is achieved, and the system design scheme is matched with chip model application, so that the illumination quality in the CIS scanning process is effectively improved, and the signal conversion effect is optimized.

Description

technical field [0001] The present invention relates to the technical field of scanner systems, in particular to a flatbed scanner system. 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 new type of image sensor. Com...
