Abstract

A sort of method and apparatus of using few matrix calculation for RGB to YCbCr color space, signal conversion, having the following steps: (1) generation of at least 2 color aberation signals, being each in association with any of the 2 digital RGB color space signals; and (2) calculation of the matrix multiplication of the first, second, third and fourth color aberation signal, being the first and the second matrix multiplication with the first and second results being used in the conversion of the digital Y color space signal, having the third matrix multiplication a third result to be used in the conversion of the digital Cb color space signal and the fourth matrix multiplication the fourth result to be used in the conversion of the digital Cr color space signal.
