<p><P>PROBLEM TO BE SOLVED: To reduce a memory bandwidth in an image processor. <P>SOLUTION: The image processor includes a compression processing unit 1 which performs compression processing for input image data. In the compression processing unit 1, a variable length encoding unit 12 reads image data of a small area from an image storing unit 11, and encodes and compresses the image data for each small area by a variable length encoding method. A data construction unit 13 divides the compressed data into first data of a predetermined data size or below and second data exceeding the predetermined data size. A data construction unit 13 collects a plurality of small areas of the second data to create third data. The data construction unit 13 creates first block data based on the first data, second block data based on the third data, and size information on the third data. The first block data are written in a first block of a fixed size corresponding to a memory. The second block data are written in a second block corresponding to the memory. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
