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 means of motion detecting unit, and when motion image is detected, by detecting partially interframe correlation or correlation in three fields, and according to the detec- tion result, by adaptively switching a plurality of proces- sings for extracting intraframe Y signal and a plurality of processings for extracting intraframe C signal.
