PROBLEM TO BE SOLVED: To provide a moving picture decoding device that derives an inter prediction information candidate suitable for parallel processing.SOLUTION: In inter prediction that is performed while partitioning a first block, which is obtained by partitioning each picture, into one or a plurality of second blocks, a spatial merge candidate generating unit 230 derives a spatial merge candidate without referring to a block included in a first block that includes a second block. In the case of a mode where a coding block is divided by a horizontal border into upper and lower prediction blocks, a reference index derivation unit 231 of a time merge candidate sets reference index information of the time merge candidate to a value of reference index information of a decoded prediction block adjacent to a left edge of a prediction block to be decoded. In the case of a mode where a coding block is divided by a vertical border into right and left prediction blocks, the reference index derivation unit sets reference index information of the time merge candidate to a value of reference index information of a decoded prediction block adjacent to an upper edge of a prediction block to be decoded.SELECTED DRAWING: Figure 14 |
