Abstract
PURPOSE:To remove luminance difference between scanning lines when the picture element of one part is saturated and to prevent picture quality from being lowered by cusing the picture element signals of the plural lines of an image pickup element to pass through an LPF respectively and clipping respective outputs at the same level to be prescribed. CONSTITUTION:The picture element signal outputted from an image pickup element 1 is amplified 2 and inputted to a 1H delaying device 14, a chrominance signal processing circuit 8 and horizontal direction LPF circuits 12 (12a and 12b). The picture element is two line-synchronized by this delaying device 14 and inputted to the processing circuit 8, a vertical direction LPF circuit 10 and the horizontal direction LPF circuits 12. The picture element signal, whose response is different to incoming light quantity per picture element, is caused to pass through the LPF circuits 12a and 12b and an average value in each line is outputted. Then, the output is clipped by clip circuits 11a and 11b with the same level to be prescribed and inputted to an operating circuit 5 after removing the level difference of respective lines. A vertical outline compensating signal is obtained by the operating circuit 5 and added to an adding circuit 4.
