Abstract
Abstract An image processing apparatus can deal with a plurality of kinds of video signals. The apparatus includes a circuit (1100, 1110,1120) for generating a signal indicating the kind of an input video signal. and magnification varying circuit for varying the aspect ratio of an image of the input video signal in accordance with a result of discrimination by the signal generation circuit. The aspect ratio of a pixel (picture element) is automatically corrected in accordance with the input video signal by the above-described circuits. Accordingly, it becomes unnecessary to manually set the aspect ratio of a pixel in accordance with the kind of the input video signal. Hence, operation is greatly simplified.
