Japan, Sept. 16 -- KDDI CORP has got intellectual property rights for 'IMAGE DECODING DEVICE, IMAGE DECODING METHOD, AND PROGRAM.' Other related details are as follows:
Application Number: JP,2024-001395
Category (FI): H04N19/52,H04N19/513
Stage: PROBLEM TO BE SOLVED: To provide an image decoding device, an image decoding method, and a program that improve encoding efficiency.SOLUTION: In an image decoding device 200, an inter-prediction unit 205 performs chained motion vector prediction of recursively adding all motion vectors derived by searching for motion vectors accumulated in a decoding picture buffer, in motion vectors of positions that are spatially or temporally adjacent or proximate to each other, to a decoding target block stored in a merge candidate list that stores candidates for a motion vector, thereby generating a chained motion vector, and deriving the chained motion vector as a candidate for a motion vector of the decoding target block, and in deriving the chained motion vector in the chained motion vector prediction, sets a starting point of the first motion vector constituting the chained motion vector to part or all of the decoding target block.SELECTED DRAWING: Figure 1 (Grant)
