Abstract

An image processor includes a video processing circuit which converts and processes a video signal. A first image processing circuit further processes the video signal processed by the video processing circuit, with emphasis on image gradation to generate image data matching the recording format of a recording apparatus. A second image processing circuit further processes the video signal processed by the video processing circuit, with emphasis on the sharpness of image contours to generate image data matching the recording format of the recording apparatus. A selecting circuit selects the first or second image processing circuit based on the type of video signal processed by the video processing circuit.
