Abstract: An encoder (100) includes circuitry (160) and memory (162) connected to the circuitry (160). In operation, the circuitry (160): selects a first table to be 5 used for a current partition to be encoded in an image of a video, from among tables that are used to correct a base motion vector in a predetermined direction using a correction value specified by an index, the tables including correction values having varying differences between indexes; writes a parameter indicating a first index to be selected from among indexes included in the first 10 table; and encodes the current partition using the base motion vector corrected using a correction value specified by the first index. 19479675_1

Abstract: A coding device (100) for coding a block to be coded included in a picture is provided with a circuit and a memory. The circuit divides the block to be coded into a first sub-block, a second sub-block, and a third sub-block in a first direction using the memory, the second sub-block being located between the first sub-block and the third sub-block, prohibits the second sub-block from being divided into two partitions in the first direction, and codes the first sub-block, the second sub-block, and the third sub-block.

Abstract: A coding device (100) performs division into a plurality of blocks by using a block division mode set obtained by combining one or more block division modes which define division types. The block division mode set comprises: a first block division mode in which the number of divisions and the dividing direction for dividing a first block are defined; and a second block division mode in which the number of divisions and the dividing direction for dividing a second block, which is one of blocks acquired by dividing the first block are defined. When a division in the first block mode results in three blocks, the second block is the center block among the blocks acquired by dividing the first block, and the dividing direction of the second block division mode is the same as the dividing direction of the first block division mode, then the second block division mode includes only a block division mode in which a division results in three blocks.

Abstract: Un codificador (100) que codifica un bloque actual en una imagen incluye circuitería y memoria. Usando la memoria, la circuitería: divide el bloque actual en un primer sub-bloque, un segundo sub-bloque y un tercer sub-bloque en una primera dirección, el segundo sub-bloque se ubica entre el primer sub-bloque y el tercer sub-bloque; impide dividir el segundo sub-bloque en dos particiones en la primera dirección; y codifica el primer sub-bloque, el segundo sub-bloque y el tercer sub-bloque.

Abstract: An encoder (100) partitions into blocks using a set of block partition 5 modes obtained by combining one or more block partition modes defining a partition type. The set of block partition modes includes a first partition mode defining the partition direction and number of partitions for partitioning a first block, and a second block partition mode defining the partition direction and number of partitions for partitioning a second block which is one of blocks 10 obtained after the first block is partitioned. When the number of partitions of the first block partition mode is three, the second block is a center block among the blocks obtained after partitioning the first block, and the partition direction of the second block partition mode is same as the partition direction of the first block partition mode, the second block partition mode includes only a block 15 partition mode indicating that the number of partitions is three. 19482302_1 (GHMatters) P114923.AU.1

Abstract: Un codificador (100) parte en bloques mediante el uso de un conjunto de modos de partición de bloque obtenidos al combinar uno o más modos de partición de bloque que definen un tipo de partición. El conjunto de modos de partición de bloque incluye un primer modo de partición que define la dirección de partición y el número de particiones para partir un primer bloque, y un segundo modo de partición de bloque que define la dirección de partición y el número de particiones para partir un segundo bloque el cual es uno de los bloques obtenidos después de que se parte el primer bloque. Cuando el número de particiones del primer modo de partición de bloque es tres, el segundo bloque es un bloque central entre los bloques obtenidos después de partir el primer bloque, y la dirección de partición del segundo modo de partición de bloque es la misma que la dirección de partición del primer modo de partición de bloque, el segundo modo de partición de bloque incluye solo un modo de partición de bloque que indica que el número de particiones es tres.
