PURPOSE:To compose a natural image from a simple input image by optimizing proper block size. CONSTITUTION:A block division part 1 divides input image data IN into plural blocks to generate input block data S1. A block analysis part 2 inputs the input block data S1 and base data S3a and generates coefficient data S2a and S2b. A block decision part 4 decides whether the respective blocks are further divided on the basis of the coefficient data S2a and outputs a redivision indication signal S4a to the block division part 1 when the blocks are redivided, and the block division part 1 redivides the input block data S2. When not, a decision end signal S4b is outputted to the block analysis part 2. A coefficient memory 5 stores the coefficient data S2b and outputs it as coefficient data S5. A block composition part 6 generates composite block data S6 from the coefficient data S5 and base data S3b. An output part 7 generates composite image data S7 from the composite block data S6. |
