IMAGE CODING APPARATUS, IMAGE CODING METHOD, IMAGE DECODING APPARATUS, IMAGE DECODING METHOD, PROGRAM AND RECORDING MEDIUM Russian patent published in 2013 - IPC H04N7/32 

FIELD: information technology.

SUBSTANCE: prediction set determining section (13) selects a prediction set from a group of prediction sets, which includes a plurality of prediction sets having various combinations of prediction modes corresponding to different prediction directions. In addition, a prediction mode determining section (11) selects a prediction mode from a prediction set selected that way. A statistical coding section (4) encodes the selected prediction set, the selected prediction mode and residual data between an input image and a predicted image formed based on the prediction set and the prediction mode.

EFFECT: performing prediction from a large number of different angles and improved prediction efficiency.
