    Abstract: Este dispositivo de codificación (100) comprende un circuito (160) y una memoria (162). En un caso en el que el circuito (160), utilizando la memoria (162), codifica un bloque de objeto en un modo de interpredicción para realizar una búsqueda de movimiento en un dispositivo de decodificación (modo de fusión en S201), el circuito: deriva un primer vector de movimiento del bloque de objeto (S203); almacena el primer vector de movimiento derivado en la memoria (162); deriva un segundo vector de movimiento del bloque de objeto (S204); genera una imagen predicha del bloque de objeto mediante compensación de movimiento utilizando el segundo vector de movimiento (S208); y en la primera derivación del vector de movimiento, utiliza el primer vector de movimiento de un bloque procesado para derivar el primer vector de movimiento del bloque de objeto.

    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: A coding device (100) for coding a block to be coded of a picture is provided with a circuit and a memory, wherein the circuit generates a first transformation coefficient using the memory by performing a first transformation on a residual signal of the block to be coded using a first transformation base, generates a second transformation coefficient by performing a second transformation on the first transformation coefficient using a second transformation base when the first transformation base matches a predetermined transformation base, quantizes the second transformation coefficient, and quantizes the first transformation coefficient without performing the second transformation when the first transformation base differs from the predetermined transformation base.
