PROBLEM TO BE SOLVED: To provide a moving picture encoding technology for reducing the amount of code of coding information by improving the encoding efficiency.SOLUTION: In inter prediction that is performed by partitioning a first block, which is obtained by partitioning each picture, into one or more second blocks, a spatial merge candidate generating unit 130 derives a spatial merge candidate without referring to a block included in the first block that includes the second blocks. 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 131 of a time merge candidate sets reference index information of the time merge candidate to a value of reference index information of an encoded prediction block adjacent to a left edge of a prediction block subject to encoding. In the case of a mode where a coding block is divided by a vertical border into left and right prediction blocks, the reference index derivation unit sets reference index information of the time merge candidate to a value of reference index information of an encoded prediction block adjacent to an upper edge of a prediction block subject to encoding.SELECTED DRAWING: Figure 13 |
