Abstract
PURPOSE:To prevent degradation of the picture quality, by providing a circuit, which reduces a parasitic signal mixed into the luminance signal, in the color solid image pickup device where a single image pickup device is so arranged that respective photoelectric conversion elements may have spectral sensitivity characteristics different in a mosaic form. CONSTITUTION:Video signal 57 corresponding to the first spectral sensitivity characteristic, video signal 46 corresponding to the second spectral sensitivity characteristic, and video signal 50 corresponding to the third spectral sensitivity characteristic are separated from the output signal of the solid image pickup device where a single image pickup device is so arranged that respective photoelectric conversion elements may have spectral sensitivity characteristics different in mosaic form. Circuit 64 which eliminates the parasitic signal of a specific frequency caused by arrangement of photoelectric conversion elements having the second or the third spectral sensitivity characteristic is provided in the circuit which processes the first video signal 57, and a signal generated by the second and the third video signals 46 and 50 is used as a control signal which controls the operation of circuit 64 by 55.
