An image processing system includes a memory management unit and an image decoding apparatus. The memory management unit receives first information regarding control of a frame memory, releases a frame in the frame memory in accordance with the first information, and outputs second information indicating the released frame. The image decoding apparatus decodes encoded image data into an image, and then stores the decoded image in the frame that the second information indicates. The image decoding apparatus then determines, according to the encoded image data, which image among the images stored in the frame memory is not to be referenced in decoding process, and outputs, as the first information, information regarding release of the frame in which that non-referenced image is stored.
