Design and Development of Digital Image Acquisition Card based on FPGA YU Qin (China University of Petroleum, Shandong Dongying 257055) Abstract: It designs an auto-adaptive high resolution image process card in this paper. The basic form of an image acquisition system is digital signal processor, A/D and D/A converter, and memory. The system scheme for video image process card is put forward. The hardware design of image acquisition card includes input and output circuit design, FPGA circuit design and DSP circuit design. The main chips that used in this system is introduced first, and then we focuses on the connection of the circuit.
