Abstract
An image processing system determines a characteristic of a moving picture, when moving-picture information is compressed, by comparing the contents of contiguous frames comprising the moving picture. The characteristic can be such that the background is not moving, but a part of the picture is moving. A compression method is selected in accordance with the characteristic and used to compress the image data. The compressed data includes the image data and information for designating the procedure to decompress the image data. When the receiver receives the compressed image data, data expansion processing is performed based on the information indicating the compression procedure. Since the image processing system compresses the image by the compression procedure best suited to the characteristic of the image, information is not lost and efficient compression can be performed.
