ABSTRACT:
An image processing apparatus includes a discriminating circuit for determining a compression ratio of an image signal input thereto, the image signal being compressed in a horizontal direction. An aperture correction control circuit is provided for controlling frequency characteristics of an aperture correcting circuit in response to the output of the discriminating circuit. Correction characteristics in an expanded image signal to be output are made equivalent to frequency characteristics of an aperture correction operation to be conducted on a television signal having a predetermined aspect ratio.
