Abstract

PURPOSE: To secure the assured correction even for the level fluctuation of a short period by correcting the level variation of the carrier chrominance signal by means of the angle-modulated luminance signal.
CONSTITUTION: The reproduced color video signal obtained from head 1 is supplied to HPF11 via gain amplifier 31, and the FM-modulated luminance signal is drawn out. This luminance signal is supplied to amplitude detector 32 to undergo the amplitude detection, and the output is sent to gain control circuit 31 via LPF33 to control the gain. Thus, the level fluctuation is compensated for the low range- converted carrier chrominance signal based on the level of the FM-modulated luminance signal contained in the reproduced color video signal. In this way, even the short period level fluctuation can be corrected assuredly.
