摘要
随着科学技术的发展,视频采集技术在日常生活中使用的越来越广泛。在视频采集系统中,用FPGA(Field Programmable Gate Array)实现串并转换,色度空间转换,去隔行处理等算法,使视频解码芯片输出的YCbCr4∶2∶2的视频格式转换到RGB格式,并通过视频DAC芯片FMS3818实现了RGB图像的输出,最后由液晶显示器显示采集到的视频图像。
With the development of science and technology, the video sampling technology is more and more widely used in our daily life. This paper introduces an algorithm in the sampling system. In order to transfer the YCbCr4：2：2 video format switch outputted by the video decoding chip to the RGB format, the article uses the FPGA（ Field Programmable Gate Array） to realize the transition from serial to parallel, the color space conversion and the interlaced progressive change etc. Through the DAC chip FMS3818, the RGB image output is realized. Finally. it displays the collected video victure bv LCD.
