Abstract

PURPOSE: To enable to perform color stabilization control operation stable and accurate, by detecting the signal around skin color with the amplitude of the difference signal between the reference color signal of skin color and the carrier chroma signal and using it for the control.
CONSTITUTION: Carrier chroma signal is fed to the variable gain amplifier 7, and the gain is set with the luminance signal separately supplied so that the gain is increased with smaller luminance signal level. Further, the output of the amplifier 7 is fed to one input terminal of the subtractor 3, where subtraction with the reference chroma signal fed to another input terminal is made. When the phase of the carrier chroma signal and the reference chroma signal is in agreement with each other, if the liminance signal is smaller, since the gain of the amplifier 7 is increased, with comparatively greater gain of the carrier chroma signal, it is in agreement with the amplitude of the reference chroma signal and judged as skin color. (and vice versa) Further, the output of difference signal from the subtractor 3 is fed to the variable mixer 8 via the amplitude detector 4, mixing 8 the carrier chroma signal with the reference chroma signal in a suitable ratio into output.
