Abstract: PURPOSE:To electrically make compensation for color aberration, to make a device compact, and to suppress the generation of a folding distortion due to a color carrier by providing with an optical low pass filter whose self-cut-off frequency is set to be low. CONSTITUTION:The picture areas of the left-hand upper part, right-hand upper part, left-hand lower part, and right-hand lower part of one picture obtained by dividing it in up-and-down and right-and-left directions are taken in charge by four CCD 2A-2D whose input sides are equipped with optical low pass filters 1A-1D. The output of each image pickup element driven by a TG 11 is sampled/ held by S/H & AGC parts 3A-3D, after AGC-processed, and converted into digital signals by A/D converters 4A-4D. Then, the cut-off frequencies of the optical low pass filters 1A-1D provided in correspondence to the CCD 2A-2D are set to be lower than a case that they are used in order to obtain an output corresponding to an entire picture display screen area. Therefore, the compensation for color aberration can be electrically made, and the large sizing of an optical system for use of color aberration compensation can be avoided.
