Abstract
A progressive scanned signal processing apparatus for inputting progressive scanned image signals and processing them as 420P signals comprises a signal processing means and a storing means in order to prevent the qualities of images of color difference signals from being lowered. A delay time required for carrying out a whole signal processing is expressed by 2×N×F (herein, N>0, N is an integer and F is time necessary for a period of one frame). Accordingly, the delay time necessary for the signal processing is expressed by the frames of even number, so that a main signal can be prevented from being replaced by a sub-signal.
