An image processing device that executes high speed overwriting of an input image with one or more partial images. A processing prediction unit judges whether overwriting is completed on all the partial images held in a small area buffer. If overwriting is completed, the overwritten partial image is compressed by an encoding unit, and the coded image is stored in a compact page memory. If overwriting is not completed, the uncompressed partial image is stored in the compact page memory. The uncompressed partial image is read from the compact page memory and is fed back to the overwriting unit through an output switch unit. The coded image stored in the compact page memory is sent to a decoding unit through the output switch unit, and is decoded to be outputted as an output image.
