VIDEO DECODING APPARATUS, VIDEO CODING APPARATUS, VIDEO DECODING METHOD, VIDEO CODING METHOD, AND STORAGE A video coding/decoding system includes: a video coding apparatus including a first reference picture list storing unit configured to store picture information of pictures, a first motion vector information storing unit configured to store motion vector information including motion vectors of blocks that are spatially or temporally adjacent to a target block to be processed, and reference picture identifiers indicating pictures that the motion vectors refer to, and a first vector predictor generating unit configured to scale a vector predictor candidate of the target block based on the picture information and the motion vector information and to correct the scaled vector predictor candidate toward 0 by a predetermined amount; and a video decoding apparatus including a second reference picture list storing unit configured to store the picture information of the pictures, a second motion vector information storing unit configured to store the motion vector information including the motion vectors of the blocks that are spatially or temporally adjacent to the target block and the reference picture identifiers indicating the pictures that the motion vectors refer to, and a second vector predictor generating unit configured to scale the vector predictor candidate for the motion vector of the target block based on the picture information and the motion vector information and to correct the scaled vector predictor candidate toward 0 by the predetermined amount. |
