IMAGE PROCESSING APPARATUS, METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To enable improvement of coding efficiency.

SOLUTION: A mode restriction level control part 321 adaptively controls intra-prediction mode used for intra prediction by an intra-prediction part 314 and a code length of binarization assigned to designation information of an optimal intra-prediction mode by a lossless encoding part 306. The intra-prediction part 314 performs intra prediction in the intra-prediction mode allowed by the mode restriction level control part 321 to select the optimal intra-prediction mode. The lossless encoding part 306 binarizes and encodes the designation information of the optimal intra-prediction mode by a code length designated by the mode restriction level control part 321. The present invention can be applied to an image processing apparatus, for example.
