摘要

A method of encoding snapshots in motion to perform inter-prediction coding in a target coding block included in a target snapshot encoding, the method of encoding snapshots in motion comprising: coding the target block of coding using a motion vector; generate a plurality of motion vector predictors; and encoding the motion vector using one of the plurality of motion vector predictors generated in the generation, in which, in the generation, (i) it is determined whether it is prohibited to obtain a temporary motion vector predictor from a block c -located that is included in a coded snapshot different from the target coding snapshot and corresponds to the coding target block (S12), applying the prohibition for coded snapshots that can be referenced by other snapshots and referring to other snapshots, and (ii) when it is prohibited to obtain the temporal motion vector predictor from the co-located block (Yes in S12), a replacement vector that replaces the temporal motion vector predictor is included in the plurality of vector predictors of movement.
