摘　　要：结合平板显示和视频数字化的发展现状,分析了模拟视频信号的处理过程,并着重对一种平板显示的色度空间变换的颜色修正进行分析,结合FPGA技术给出了实现视频信号色度空间变换框图。实际应用中芯片SAA711A性能指标足以满足色度空间转换的要求,工作非常稳定,在平板显示器上复现的图像也比较稳定。With the development of the flat panel display and digital video, the process of analog video is analyzed in this paper. The color gamut transform between a kind of flat panel display and CRT is discussed in detail. A practical diagram block is given using the technology of FPGA. In practical applications, SAA711A~′s performance meets the requirement of this color gamut transform and it works rather stably. Finally image regained is displayed stably on the flat panel display.
