Por ejemplo, la primera información de atributos que se va a predecir y la segunda información de atributos a la que se va a hacer referencia se pueden incluir en el mismo punto tridimensional. Por ejemplo, la primera información de atributos que se va a predecir y la segunda información de atributos a la que se va a hacer referencia se pueden incluir en diferentes puntos tridimensionales. Por ejemplo, la primera información de atributos y la segunda información de atributos se pueden almacenar en un primer componente y un segundo componente, respectivamente.

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.
