Abstract
PURPOSE:To eliminate the deviation of the gamma correcting characteristic or the mnemonic characteristic of a luminance signal and a chrominance signal and to faithfully reproduce an image by matching the non-straight line characteristic of the luminance signal and the chrominance signal according to the saturation of the chrominance signal. CONSTITUTION:A correcting signal generator 20 to detect the saturation (chroma) of the chrominance signal inputs two color different signals R-Y and B-Y and generates a correcting signal S1. This correcting signal S1 corrects the characteristic of a Y process part 4. According to the saturation (chroma) of the chrominance signal, control is executed so that the non-straight line characteristics of the luminance signal and the chrominance signal can be matched. Thus, the deviation of the gamma characteristic or the mnemonic characteristic of the luminance signal and the chrominance signal is removed and the faithful reproduction of the image can be executed.
