PREDICTION IMAGE CODING DEVICE, PREDICTION IMAGE CODING METHOD, PREDICTION IMAGE CODING PROGRAM, PREDICTION IMAGE DECODING DEVICE, PREDICTION IMAGE DECODING METHOD, PREDICTION IMAGE DECODING PROGRAM Russian patent published in 2019 - IPC H04N19/105 H04N19/52 H04N19/44 

FIELD: computer equipment.

SUBSTANCE: prediction image decoding method, in which a prediction area prediction block type is decoded and stored as a pre-decoded prediction information into a prediction information storage means; selecting a candidate for motion information to be used when generating a prediction signal of the prediction target region, serving as the next prediction region; in accordance with the number of selected candidates for motion information, merging unit information is decoded using the selected candidate for motion information, and movement information or decoding any one of the merging unit information or movement information; and storing motion information to be used when generating the prediction signal of the prediction target region in the prediction information storage.

EFFECT: technical result consists in improvement of efficiency of decoding.
