Abstract: An image processing system preferably for color processing, is constituted by an image memory device having an image memory (42), and a reader and a printer which are connected to the image memory device, and also has an electronic apparatus (20) which outputs commands for operating the processing system as a facsimile apparatus through a reader/printer interface (41) of the image memory device, and has an image compression unit (22) and a communication unit (30).

Abstract: An image processing apparatus transmits image data to a communication partner by selectively using one of a first transmission mode and a second transmission mode. The apparatus has a display unit that displays first image information representing the communication partner and second image information representing a communication state. In the first transmission mode, the first image information is displayed independently from the second image information such that the second image information does not overlap the first image information and such that the first image information is not included in the second image information. In the second transmission mode, the second image information is displayed such that the first image information is included in a part of the second image information.

Abstract: This invention is to process a large quantity of color image data at high speed with minimum deterioration of image quality. One-color image data input to or output from a reader/printer unit (40) is divided into a plurality of blocks. A CPU (26) performs parallel processing of transfer of block data to an IMEM (24) of a main body (20) or transfer from the IMEM (24) to an IMEM (42) of the reader/printer unit (40), and compression of the block data from the IMEM (24) by an ICU (22) or expansion of the block data received through a CCU (30) by the ICU (22) and storage of the expanded data in the IMEM (24), thereby processing the color image data at high speed.
