Abstract
An image processor in which an input device inputs image data. Image data of a subject pixel is smoothed in accordance with the image data of the subject pixel and peripheral pixels of the subject pixel. A judgment is made relative to the level of the image data of the image data of the subject pixel and the peripheral pixels. The image processor selectively outputs one of the smoothed image data and the image data of the subject pixel, based on the judgment.
