摘　　要：人类获得信息的主要方式是视觉。通常情况下颜色有两种描述方式,一种用RGB色度空间表示,一种用YCb-Cr色度空间表示。在视频处理过程中,通常获得显示的颜色用RGB色空间来表示,但为了降低带宽和存储量,引入了YCb-Cr色空间。YCbCr色空间是亮度和色度的概念,而人眼对亮度和色度比较敏感,所以在传输过程中使用YCbCr色空间易于压缩,方便传输和处理,可以有效地降低带宽和存储量。在此,通过Verilog语言实现RGB到YCbCr色空间的转换,并通过FPGA进行了验证,得到正确的结果。Human obtains information mainly through vision.Under normal circumatances,there are two kinds of color description：RGB color space and YCbCr color space.In the video process,normally the obtained and displayed colors are described by RGB.YCbCr color space is introduced to reduce the bandwidth and information storge.YCbCr color space is the concept of color and brightness,and human′s eyes are more sensitive to brightness and color,so using YCbCr color space in the transmission is convenient for compacting,transmission and disposal and also effectively reduces the bandwidth and information storge. The conversion of RGB to YCbCr is realized by Verilog language and verified through FPGA,the correct result is gained.
