Abstract
A method of color components compression is provided. In the present method, when receiving video data encoded by a 4:4:4 sampling format, color components of each set of neighboring pixels in the video data is down-sampled and a first difference of the color components between the video data before and after down-sampling in a down-sampling mode is calculated. Then, the color components of each pixel in the video data are truncated and a second difference of the color components between the video data before and after truncation in a truncation mode is calculated. The first difference and the second difference are compared and the down-sampling mode or the truncation mode that has a smaller difference is selected to compress the video data into a 4:2:2 sampling format.
