Abstract

PURPOSE:To simplify the circuit constitution, by separating a signal from a color device into a luminance signal and chrominance signal and and outputting them form different terminals. CONSTITUTION:A luminance signal Y and color difference signals B-Y and R-Y are obtained from an input color signal at a video process circuit 102. A control signal generating circuit 103 outputs a synchronizing signal and a color subcarrier signal, takes synchronism for the processing circuit 102 and scans an image pickup device 101, and inputs the color subcarrier signal to modulators 104, 105. The phase of this subcarrier is shifted at a phase shifter 106. The outputs of the modulators 104, 105 is mixed 107 and a chrominance signal C is outputted to the output. The luminance signal Y from a processor 102 is directly outputted.
