Summary:PROBLEM TO BE SOLVED: To provide a video signal processor capable of improving image quality without generating a pseudo contour at all times even in receiving a various kinds of input video signals. SOLUTION: The apparatus is provided with a band limiter 2 for limiting the band of an input video signal; an analog/digital converter 3 for converting an analog signal from the limiter 2 into a digital signal by using a specific clock signal; and a pixel converter 4 for controlling the clock frequency of the section 3 to convert pixels into specifications of a signal having predetermined horizontal pixels, and controlling the cut-off frequency of the section 2 corresponding to the input video signal. This apparatus is configured to remove a turning-back component due to sampling of the analog/digital conversion, and clear image display can be achieved. COPYRIGHT: (C)2005,JPO&NCIPI
