In an image processing system, an image-input-processing unit divides an original image into portions so as to generate divided original images, and writes the divided original images in an encoder-side memory so that luminance data and chrominance data of each of the divided original images are stored in different storage areas. When predictive coding is performed, the encoding unit divides a reference image into portions so as to generate divided reference images which include information necessary for predictive coding of the divided original images, stores the divided reference images. The decoding unit divides and decodes an inputted encoded image so as to generate divided decoded-data sets, and writes the divided decoded-data sets in a decoder-side memory so that luminance data and chrominance data in each of the divided decoded-data sets are stored in different storage areas.
