Abstract
A system includes an image transmitting unit and an image receiving unit. The image transmitting unit has a compression unit for compressing, in accordance with a provided compression parameter, a pixel block in image data, and a first transmitting unit for transmitting the compressed data to an image receiving unit in the system. The image receiving unit has a receiving unit for receiving the compressed data, a decompression unit for decompressing the received compressed data, a determination unit for determining a compression parameter based on the result of the decompression, and a second transmitting unit for transmitting the determined compression parameter to the image transmitting unit. The compression unit compresses an untransmitted second pixel block in the image data to be compressed in accordance with the compression parameter transmitted from the second transmitting unit.
