Abstract
A video signal processor for improving a detection precision of Y motion and C motion, preventing erroneous judgment, and preventing deterioration of image quality without being influenced by the band of the luminance signal or the phase of a sub-carrier of chroma. The processor includes a provisional 3D Y/C separation motion detection circuit, extracting Y signals of a current frame and a past frame based on composite video signals of three adjacent lines of the current frame and the past frame, detecting Y motion in accordance with a difference of Y signals of the current frame and the past frame by a Y motion detection unit, outputting a Y motion detection signal MVD, detecting C motion by a C motion detection unit based on Y signals of three adjacent lines in the current frame, outputting a C motion detection signal MVD, and selecting, according to the motion detection signals MVDand MVD, the difference of the C signals separated from the current frame and the past frame or a predetermined valueto generate a C motion coefficient.
