Abstract

An image processing system provided with a line sensor for reading image signals in line units. First, the line sensor scans a document in a normal direction. At this time the image data obtained by the scan are subjected to image processing such as compression and the like. Areas of image data that cannot be processed to the high moving speed of the scanner are subjected to image processing by later performing a scan in the reverse direction.
