Abstract: This three-dimensional data encoding method includes: if a first flag indicates a first value (Yes at S4481), generating a first occupancy pattern that indicates the occupancy state of a plurality of second adjacent nodes including a first adjacent node, the parent node of which is different from a target node included in an N-branched tree structure (where N is an integer of 2 or greater) of a plurality of three-dimensional points included in three-dimensional data (S4482); without dividing the target node into a plurality of child nodes, determining, on the basis of the first occupancy pattern, whether first encoding that encodes a plurality of three-dimensional position information included in the target node is usable (S4483); if the first flag indicates a second value different from the first value (No at S4481), generating a second occupancy pattern that indicates the occupancy state of a plurality of third adjacent nodes not including the first adjacent node, the parent node of which is different from the target node (S4484); determining, on the basis of the second occupancy pattern, whether the first encoding is usable (S4485); and generating a bit stream that includes the first flag (S4486).

Abstract: A three-dimensional encoding method for entropy-encoding a bit string that represents an N-branched tree structure (N=integer greater than or equal to 2) of a plurality of three-dimensional points included in three-dimensional data using an encoding table selected from a plurality of encoding tables, the bit string including N-bit information for each node in the N-branched tree structure, the N-bit information including N pieces of 1-bit information that indicates whether or not a three-dimensional point exists in each of N child nodes of the corresponding node, each of the plurality of encoding tables being provided with a context for each bit of the N-bit information. In the entropy-encoding, each bit of the N-bit information is entropy-encoded using the context provided for the bit in the selected encoding table.

Abstract: A moving picture coding method includes: coding (S111) a first flag indicating whether or not temporal motion vector prediction is used; when the first flag indicates that the temporal motion vector prediction is used (Yes in S112): coding (S113) a first parameter for calculating the temporal predictive motion vector; wherein when the first flag indicates that the temporal motion vector prediction is not used (No in S112), the first parameter is not coded (S116).

Abstract: An image coding method includes: performing context arithmetic coding (S511) to consecutively code (i) first information indicating whether or not to perform sample adaptive offset (SAO) processing for a first region of an image and (ii) second information indicating whether or not to use, in the SAO processing for the first region, information on SAO processing for a region other than the first region, the context arithmetic coding being arithmetic coding using a variable probability, the SAO processing being offset processing on a pixel value; and performing bypass arithmetic coding (S512) to code other information which is information on the SAO processing for the first region and different from the first information or the second information, after the first information and the second information are coded, the bypass arithmetic coding being arithmetic coding using a fixed probability.

Abstract: Un método de codificación de imágenes en que se transforman un componente croma y un componente luma de una imagen de entrada que incluye uno o más bloques de transformación para codificar la imagen de entrada. El componente luma tiene el mismo tamaño que el actual bloque de transformación. El componente croma es menor que el actual bloque de transformación. En el método, cuando el actual bloque de transformación tiene un primer tamaño mínimo, el componente croma se transforma sobre la base de un bloque resultante de unir una pluralidad de los bloques croma que tienen el mismo tamaño que el bloque luma y, cuando el actual bloque de transformación tiene un tamaño diferente del primer tamaño mínimo, no se codifica una unidad CBF que indica si los coeficientes del componente croma incluyen o no un coeficiente que no es cero.
