Abstract
A filter for motion adaptive Y/C separation, which is capable of obtaining image of high resolution and little picture quality degradation in the case where an image is switched from static one to motion one or vice-versa, is provided with a filter for extracting Y signal outputting Y signal and a filter for extracting C signal outputting C signal, by detecting whether image is motion one or static one by a motion detecting unit, and when motion image is detected, by detecting partially interframe correlation or correlation in three fields, and according to the detection result, by adaptively switching a plurality of processings for extracting intraframe Y signal and a plurality of processings for extracting intraframe C signal.
