Abstract
PURPOSE: The AGC circuit is added to each of the luminance signal and color difference signal individually at the front stage of the gamma correction circuit. And in case the level of AGC circuit is under a prescribed level, each AGC circuit is made inactive to maintain the luminance signal input, etc. at a normal level. Thus, a high-fidelity reproduction picture can be obtained.
