摘　　要：人类获得信息的主要方式是视觉,通常情况下颜色有2种描述方式,一种是RGB色度空间表示,一种是YCbCr色度空间表示。然而,普通的RGB颜色空间对视频的显示存在很多问题,将其转换为YCbCr颜色空间能够很好地适应现代社会的要求,本文正是采用一种新的方法,通过FPGA成功地将其转化,并得到正确的结果,此方法内部变量少、算法优点突出、实时性好,十分易于在实际工程中实现。People get information always by means of vision, there are two methods to describe color, one is RGB color space, and the other is YCbCr color space. However, the common display of RGB color space for video has many problems, when we transform color space to YCrCb color space, it can satisfy the requirement of modern society, this paper adopts a new method which can transform the color space successfully and achieve right outcome. The methed has many characterics, such as few parameters, real-time, and can put into practical project easily.
