PROBLEM TO BE SOLVED: To perform memory access efficiently in moving image encoding where random access is ensured.SOLUTION: A moving image encoder for dividing a screen, being referred when encoding a moving image, into grids, i.e., lattice-like data storage areas, and associating the grids and the addresses of a storage device for storing the data in the grids, has an image compression unit 152 for compressing the data stored in each grid by a reversible compression system for each grid, and a redundant arrangement unit 153 for arranging the compression data in an adjacent grid redundantly so as to continue the compression data in a target grid, when the compression data in a grid adjacent to the target grid can be arranged in the target grid to be processed. |
