Abstract
Abstract The present invention provides a multi-function image processing apparatus including a generating device for generating serial-scanned image data which has an overlap portion and a predetermined width and a writing device for writing the image data generated by the generating device in a state where the overlap portion has been deleted in such a manner that the image data is stored in a memory. The apparatus many also include a reading device for reading image data in such a manner that at least a portion of the image data overlaps when the image data having a predetermined width is, by serial scanning, read from the storage device which stores the image data and a processing device for processing the image data which has been read out.
