摘要：FPGA can solve the lack of custom circuit, and overcome the original programmable gate device limited number of faults. The paper presents application of FPGA in high-speed CMOS digital image acquisition and color recognition system. Color recognition system is mainly composed of analog and digital two parts. The analog part mainly used photoelectric signal conversion, amplification and filtering the noise signal. The digital part is mainly used for digital signal in the sampling of the A/D median filter, check the log table, logarithm ratio, and the display operation. High frame rate CMOS imaging unit mainly consists of a CMOS image sensor and control chip FPGA, it is the imaging system components, using the image to capture fast moving objects, the circuit output for digital image data. This paper describes the SCCB bus configuration method and image acquisition part of the structure. ? 2014, Journal of Chemical and Pharmaceutical Research. All rights reserved.
