A video signal processing circuit of a solid-state image sensor (CCD) type color video camera

摘要

The present invention relates to a video signal processing circuit of a CCDD type color video camera, and more particularly to a gamma correction circuit portion, a delay circuit portion, a color signal processing portion, and a luminance signal processing portion.;Therefore, the gamma compensation process is performed before the luminance and color signal separation, and the horizontal level noise due to the gamma compensation can be eliminated by compensating the DC level fluctuation due to the gamma compensation process to the luminance signal processing unit, There is an advantage that the chip size can be reduced when integrated circuits are formed.
