Motion picture coding apparatus, motion picture coding method and computer readable information recording medium |
摘要 |
A motion picture coding apparatus divides an image into plural blocks and codes the image; determines a coding mode to be used for each of the blocks; determines, for coefficients of each of the plural blocks coded in the determined coding mode, a position for which coefficients in the block are replaced by "0" based on rate information; determines whether a to-be-processed block is a first block for which referring to pixel values of an upward adjacent block is not allowed; changes, for coefficients of a block of DC components after orthogonal transformation or quantization in the block determined as the first block, the determined position to a position at which the number of coefficients to be replaced by "0" is reduced; and replaces coefficients of the block of DC components after orthogonal transformation or quantization in the block determined as the first block based on the changed position. |
