There is provided an image encoding device capable of realizing a high-speed orthogonal transformation and coping with encoding standard of various format configurations and block sizes. The image encoding device (1) includes a first one-dimensional orthogonal transformation unit (10), 2-port memory (20) for transfer, a second one-dimensional orthogonal transformation unit (30), a first address generation unit (40), a second address generation unit (50), a coefficient table holding unit (60), a parameter set storage unit (70), and a control unit (80). The control unit (80) performs control so that the first one-dimensional orthogonal transformation unit (10) and the second one-dimensional orthogonal transformation unit (30) executes one-dimensional orthogonal transformation for each block of the specified size in parallel and performs control so that the first address generation unit (40) and the second address generation unit (50) supply, in parallel, addresses corresponding to the specified size to the 2-port memory (20) for transfer. |
