Abstract

PURPOSE: To ensure the highly stabilized signal process with a simple circuit constitution by filtering the high-frequency component of the video signal and then giving the envelope curve detection to the output of the high-frequency component to obtain the DC-reproduced signal.
CONSTITUTION: HPF12 filters the high-frequency component from the video signal obtained by multiplying the plural color components which are drawn out of the color TV camera, and the envelop curve detection is given to the output via envelope curve detector circuit 91 and 92 to obtain the DC-reproduced signal. And the direct gamma correction and the process amplification such as the white clip and the like are given to the output signals of circuit 91 and 92 via process circuit 101 and 102 of the high-band side. Thus, the highly stabilized signal process is possible through a simple circuit constitution and with just one DC component reproduction.
