Abstract

PURPOSE:To improve a picture quality and reduce the power consumption by constituting a color signal processing circuit by use of two CCD1H delay elements. CONSTITUTION:R-Y and B-Y color difference signals which have been input to the input terminal 1 and 2 are led into the modulator 4 through the comb line filter consisting of the first adder 10, the feedback circuit 11, the second adder 13, and the one horizontal scanning period delaying circuit (CCD1H delaying circuit for a low frequency signal) 12 which has used the charge coupling element for a low frequency signal, and the comb line filter 14' consisting of the first adder 10', the feedback circuit 11', the second adder 13' and the CCD1H delaying circuit 12' for a low frequency signal, respectively, are quadrature-two-phase-modulated by the chrominance carrier which has been led to the input terminal 3, and are output as chrominance signals from the output terminal 9.
