P To reduction a load of traffic ON a transmission line and a load of display processing ON an image display device. PSOLUTION: A rectangular region including differential data is detected from temporally neighboring two frame images and an overlapping region is detected further from neighboring two rectangular regions. If the overlapping region, for which a ratio of the area occupied in a latest rectangular region between corresponding two rectangular regions is a motion picture determination area reference DL or more, is continued for a motion picture determination number-of-times reference ML and the latest rectangular region between the two rectangular regions corresponding to the overlapping region corresponding to the motion picture determination number-of-times reference ML is determined as a motion picture region. In this motion picture region, image data in a region, that is not overlapped with the last update region, that is a last output target and are compressed at a first compression rate and image data in an overlapping region between the motion picture region and the last update region are compressed at a second compression rate higher than the first compression rate and are output.
