    Abstract: A coding device (100) that codes coding target blocks of an image is provided with a processor (a1) and memory (a2) that is connected to the processor (a1). The processor (a1) generates, for a motion, a first predicted image having an integer pixel unit on the basis of a motion vector, and uses an interpolation filter to interpolate the values of the minimum pixel positions between a plurality of integer pixels included in the first predicted image, thereby generating a second predicted image, and, on the basis of the second predicted image, codes coding target blocks. Usage of the interpolation filter involves switching between a first interpolation filter and a second interpolation filter in which the number of taps differs from the first interpolation filter.

    Abstract: An encoder partitions into blocks using a set of block partition 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 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 partition mode indicating that the number of partitions is three.

    Abstract: Se proporciona un codificador (100) que incluye: circuitería; y una memoria acoplada a la circuitería, en el cual en operación, la circuitería: genera una imagen de predicción de un bloque actual a ser procesado, por medio del uso de un primer vector de movimiento (paso S3001); y actualiza una tabla de predictores de vectores de movimiento basados en la historia (HMVP) por medio del uso de un primer candidato que tiene el primer vector de movimiento, la tabla de HMVP almacena, en un método de primera entrada-primera salida (FIFO), una pluralidad de segundos candidatos cada uno que tiene un segundo vector de movimiento usado para un bloque procesado (paso S3002), y en la actualización de la tabla de HMVP, la circuitería: determina si un tamaño del bloque actual es menor que o igual a un tamaño umbral (paso S30021); y omite la actualización de la tabla de HMVP (paso S30022) cuando se determina que el tamaño del bloque actual es menor que o igual al tamaño umbral (Si en el paso S30021).

    Abstract: A coding device (100) is provided with a circuit (160) and a memory (162) connected to the circuit (160). The circuit (160): selects, from a plurality of tables which are used, during an operation, to correct a reference motion vector into a predetermined direction using a correction value designated by an index, and which have correction values with respectively different intervals between indexes, a first table used for a partition to be coded of an image in a moving image; writes a parameter indicating a first index to be selected from among indexes included in the first table; and codes the partition using the reference motion vector corrected by means of a correction value designated by the first index.
