ABSTRACT:
A method and apparatus in which images on the front and back sides of a double-sided original are serially connected on one scanning line, subjected to image processing and converted into binary image data, and immediately separated into the front and back side images again. One of the front and back side images is compressed and transferred to a SCSI bus, and the other is temporarily stored in a graphic video RAM and can be displayed or printed. After the former image is completely compressed and transferred, the latter is read from the video RAM, compressed by the compression circuit and then transferred to the SCSI bus.
