Color picture signal processing method and color picture using the method

摘要

A color picture signal processing method includes the steps of: (a) inputting picture signal data; (b) converting the picture signal data to data of luminance Y and color differences Cr and Cb on a Y-Cr-Cb space; and (c) executing a color difference matrix calculation by using at least one pair of equations. By the invention, it may be is possible to obtain a color picture signal wherein a hue circle of a flesh color is suppressed.
