圧回路。[Claims for Utility Model Registration] A ring emphasis signal that emphasizes the rising and falling parts of the luminance signal is multiplexed onto the luminance signal and derived, and a phase modulated color signal is input to a phase detection circuit to detect the color signal component. In a color video camera that demodulates and derives the image enhancement signal, a rectifier circuit that rectifies the ring image emphasis signal and a color signal suppression circuit that uses the output of the rectifier circuit as a control input and the color signal component as a signal input are respectively arranged. Color noise suppression circuit for video cameras.
