摘　　要：采用FPGA作为视频采集控制和图像处理芯片,配置NiosⅡ软核,在FPGA片内完成图像处理和图像显示控制,简化了硬件电路和软件程序的设计。在FPGA片内编写视频采集时序,并配置NiosⅡ控制软核,模拟视频数据经视频解码芯片输出ITU-RBT.656格式数据送入FPGA,通过时序控制和NiosⅡ软核把视频解码数据依序存储在SSRAM中,并进行裁剪、交织、颜色处理。This paper takes FPGA as video capture control and image processing chip, configure NiosII processor, processing image in FPGA, that simplify hardware circuit design and software design. Designing control program and burning it into FPGA, configuring NiosII processor, analog video signal captured by video decode chip and output the ITU-RBT.656 data sequence, the data sequence is captured by FPGA, through time scheduling and NiosII processor control , put the decoded data sequence into SSRAM, and take image cut out , interlace and color process and so on.
