For the real-time broadcast and storage of the high-resolution images,a real-time image acqui-sition and processing scheme based on FPGA and DSP architecture is proposed.In this system,two DSPs in series of TI DM368 are designed as core processors for image encoding and decoding with the encoded mode of H.264.FPGA in series of EP2C35 is used as coprocessor for image acquisition,color space conversion and the images transmission after encoding and decoding.This scheme realizes the vide-o and image processing for the infrared and visible light and results show that the operation is stable and reliable,the interfaces are flexible.In addition,several formats of video stream can be acquired and pro-cessed by simple modifications.
