摘要

By the present invention, when a reference picture index of a block to be encoded differs from the reference picture index included in encoding information of a reference block adjacent to the block to be encoded, a scaling process can be executed to associate a movement vector included in the encoding information of the reference block with the picture interval distance between a picture to be encoded in which the block to be encoded is present, and a reference picture that is specified on the basis of an index of the reference picture of the block to be encoded. An upper limit is set for repetitions of the scaling process derived from the encoding information when a reference candidate list is generated for a block to be encoded.
