Abstract
PURPOSE:To efficiently process image data with plural compressors or expanders by assigning a prescribed proportion of the unprocessed data volume to a compressor or expander, which terminates its assigned processing, at each time of termination of the assigned processing of this compressor or expander. CONSTITUTION:A control part 4 of plural compressors or expanders 2-1 and 2-2 which take partial charge of processing and perform the processing in parallel is provided with a means (division processing part 5) which assigns a prescribed proportion of the unprocessed data volume of image data to a compressor or expander at each time of termination of the assigned processing of this compressor or the expander. Consequently, the data volume assigned to compressors or expanders 2-1 and 2-2 is reduced according as the processing is advanced, and the data processing time is shortened. Thus, processing periods of respective compressors or expanders 2-1 and 2-2 which process image data are averaged, and they are equally used.
