Abstract
A copying apparatus includes an input device for inputting image data, a processing circuit for performing mosaic processing of the input image data, and a reproduction circuit for reproducing an image based on the processed image data. The processing circuit divides the input image data into a plurality of block areas and paints each block area with a uniform color according to the image data in the area so that the resolution of the image data is lower than the resolution of the original image.
