ABSTRACT:
A main signal motion detection signal and a multiplex motion detection signal are processed to obtain a compensated motion detection signal. This signal is a motion detection signal for a portion other than a portion having an aspect ratio of 4:3. Thus, a television signal processor is provided which eliminates quality differences between images in the portion having an aspect ratio of 4:3 and images in the other portion having a different aspect ratio.
