Abstract

The invention is to achieve, in a multifunction multifunction system applicable to a copying apparatus or a printer, automatic switching of an image processing method and a compression/expansion method for each compressed packet image (tile image). this object is achieved by a system including a storage unit for storing image data read by an image reading unit; a packet data generation unit for dividing the image data into plural tiles of a predetermined size and generating, for each tile, packet data composed of a header portion and an image data portion, the header portion including identification information for determining an image processing method for an image data portion corresponding to the header portion; a transfer unit for transferring the packet data corresponding to each tile from the storage unit; and an image processing unit for entering the packet data transferred from the transfer unit and utilizing an image processing method corresponding to the identification information described in the header portion of the packet data to apply an image processing to the corresponding image data portion.
