PROBLEM TO BE SOLVED: To suppress the increase of a buffer capacity and the decline of a processing speed even when handling the image data of a large size. SOLUTION: An image processing part is constructed by connecting a plurality of image processing modules to buffer modules; wherein each the image processing modules has a different kind or content of image processing to be performed and the function of acquiring image data with unit data amounts from the module in a preceding stage to perform image processing and to output the image data or an image processed result which has been image processed to the module of the subsequent stage, and buffer modules set to have the image data from the module of a preceding stage written in a buffer and to have the image data stored in the buffer read by the module of a sebsequent stage. In the image processing part, each buffer module compares the sizes of the successively input image data to identify compression/de-compression (120-136), compresses the image data and then writes in the buffer when de-compression (142), and performs extension processing and then outputs to the image processing module in the subsequent stage when reading from the buffer.
