MOVING PICTURE CODING DEVICE, MOVING PICTURE CODING METHOD, AND MOVING PICTURE CODING PROGRAM, AND MOVING PICTURE DECODING DEVICE, MOVING PICTURE DECODING METHOD, AND MOVING PICTURE DECODING PROGRAM Russian patent published in 2017 - IPC H04N19/52 

FIELD: physics.

SUBSTANCE: moving image decoding device includes a decoding unit for decoding information representing a predicted motion vector (PMV) to be selected from the list of candidates for the PMV; a block for generating PMV candidates to obtain a plurality of PMV candidates and creating a list of PMV candidates; a block for removing redundant PMV candidates having the same values of vectors from the list of PMV candidates while retaining at least one candidate; a block for adding PMV applicants when the number of PMV candidates on the PMV candidate list after removing the surplus PMV candidate is less than a certain number of PMV applicants; the PMV selection block based on the information representing the decoded PMV to be selected; and the motion vector by computation unit by summing the selected PMV and the difference of the motion vectors.

EFFECT: increasing the efficiency of video decoding.
