Abstract: A design of high-speed image communication system which is controlled coordinately by DSP and the CPLD is introduced. The entire image communication system consists of image capture, image signal processing and the control, the USB transmission and the control, the terminal image return and storage and so on. The system uses high-speed USB2.0 interface as image transmission. This system has been applied successfully in a high-speed and high-accuracy industrial project of an image processing and the recognition. The image signal not passing through compression processing does not influence the following processing, therefore, compared with general image capture, the effect of the image processing and the recognition is better and it has met the special needs for special occasion.
