CONTOUR CORRECTION CIRCUIT

PROBLEM TO BE SOLVED: To provide a contour correction circuit capable of contrastively correcting contours of without being affected by the deviation of the group delay characteristic of an analog signal processing circuit, when correcting primary color signals R, G and B of a color television camera 21. SOLUTION: In this contour correction circuit which extracts an optical frequency component from a Y signal generated by mixing digital primary color signal to generate a contour signal and adds the contour signal to the digital primary color signals, a channel where the contour signal is added to a green signal addition circuit 30G and a channel where the contour signal is added to red and blue signal addition circuits 30R and 30B are provided with digital delay circuits 36G and 36R/B adjusting a phase in one pixel unit and digital filters 37G and 37R/B adjusting a phase within one pixel, thereby properly setting the delay quantity of these delaying means and correcting the phase deviation of the digital primary color signal caused by the deviation of the group delay characteristic in an analog signal processing circuit.
