Abstract

An image of an original mounted on a platen is converted into image data by a CCD. An original region detection unit detects the region of the original mounted on the platen from the image data. According to this detection, the writing address of the image memory is controlled so that image data of the center of the original mounted region is written into an address matching the center of the sheet. As a result, various image editorial processes can easily be carried out in a digital copy machine.
