VIDEO SIGNAL PROCESSING CIRCUIT OF SOLID-STATE IMAGE PICKUP ELEMENT TYPE COLOR VIDEO CAMERA

摘要

PURPOSE: To obtain a video signal processing circuit of a CCD type color video camera. ;CONSTITUTION: A CCD type gamma camera is constituted to perform a gamma compensation processing before illuminance and a chrominance signal is separated and horizontal axis noise due to gamma compensation is removed by compensating fluctuation of a DC level due to the gamma compensation processing by an illuminance signal processing part 50. Conseqeutly, not only image quality is improved but chip size is reduced when a circuit is integrated.;COPYRIGHT: (C)1994,JPO
