Abstract
A video signal processing system improves the image quality displayed in a CRT or printed by a video printer. In order to produce natural and fine video signals, pixel data corresponding to an intermediate position between two neighboring pixels, are produced from pixel data of the neighboring two pixels. The pixel data corresponding to the intermediate position is produced by a convolution operation with respect to the pixel data of the two neighboring pixels and a quantized value of an impulse response signal.
