YUV与RGB之间的转换

Inter-transformation between YUV and RGB

首先对色彩空间作了简要的介绍,分别介绍了各种色彩空间的原理、YUV格式以及YUV与RGB的关系,并且给出了换算公式,将YUV的色彩空间与RGB的色彩空间的大小进行了比较。最后介绍了YUV的部分取样原理,并分别将YUV444、YUV422、YUV411和YUV420这四种取样方式进行了比较。

Firstly,the article makes an introduction to YUV color space and the principles of different color spaces separately.Then,it makes an introduction to YUV formats and their relationship to RGB provides the reducted formula and compares the color space of YUV with the size of the colour space of RGB.In the end,it introduces the subsampling principle of YUV and has compared these four kinds of sample ways separately.
