Abstract:
1. An image pick-up apparatus comprising an image pick-up device and a filter circuit, the image pick-up device comprising: said filter circuit performing filter processing of the video signals outputted from the plurality of output circuits to modify pixels near the boundary of the areas; said scanning circuit being configured to divide the scanning area so that a boundary has a plurality of horizontal and vertical boundary portions, each boundary portion having a length of at least one pixel unit; and said filter circuit being configured to calculate a filter coefficient for each pixel in the scanning areas and comprising: a unit configured to store pixel values of all pixels in said pixel portion in a memory; a unit configured to select a sub-portion of all pixels in the memory, the sub-portion being a pixel array having M rows and N columns which includes a target pixel whose filter coefficient is being determined; and sum signal values of pixels in the M rows by N columns array to obtain a filter coefficient representing an influence on the target pixel of pixels in said M by N array which occupies adjacent portions of the areas divided by said boundary.
