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.

Abstract: A method for coding video, the method including: a flag coding step (S111) for coding a first flag indicating whether or not temporal motion vector prediction is to be used; and a first parameter coding step (S113) for coding a first parameter for calculating a temporal predictive motion vector when the first flag indicates that the temporal motion vector prediction is to be used (S112: Yes), whereby the first parameter is not coded (S116) when the first flag indicates that the temporal motion vector prediction is not to be used (S112: No).

Abstract: An image encoding method comprises an encoding step (S911) of encoding coefficient information, a first flag that indicates whether to quantize one or more blocks using a plurality of quantization matrices, a second flag that indicates whether the plurality of quantization matrices are included in a sequence parameter set, and a third flag that indicates whether the plurality of quantization matrices are included in a picture parameter set, and a quantization step (S912) of quantizing a plurality of coefficients. When one or more blocks are to be quantized using a plurality of default matrices, the first flag indicating that one or more blocks are to be quantized using the plurality of quantization matrices, the second flag indicating that the plurality of quantization matrices are not included in the sequence parameter set, and the third flag indicating that the plurality of quantization matrices are not included in the picture parameter set, are encoded in the encoding step.

Abstract: This image encoding method encodes at least one unit contained in a picture, and includes: a first flag generating step (S221) for generating a first flag indicating whether or not the times that a virtual decoder reads encoded data from a buffer for storing the encoded data are set in units of the units; a second flat generating step (S222) for, when the times are set in units of the units, generating a second flag indicating whether the intervals between the read times of the plurality of units are fixed or arbitrary; and a bitstream generation step (S223) for generating an encoded bitstream containing the encoded data, the first flag, and the second flag.

Abstract: An image decoding method which can improve both image quality and coding efficiency is an image decoding method for decoding a coded stream which includes a plurality of processing units and a header for the processing units, the coded stream being generated by coding a moving picture, the processing units including at least one processing unit layered to be split into a plurality of smaller processing units, the image decoding method including specifying a hierarchical layer having a processing unit in which a parameter necessary for decoding is stored, by parsing hierarchy depth information stored in the header (S101), and decoding the processing unit using the parameter stored in the processing unit located at the specified hierarchical layer (S102).

Abstract: Un método de decodificación de imágenes incluye: dividir un bloque actual en sub-bloques; deducir, para cada sub-bloque, uno o más candidatos de información de predicción; obtener un índice; y decodificar el bloque actual utilizando el candidato de información de predicción seleccionado utilizando el índice obtenido. La deducción incluye: determinar si un bloque adyacente que es colindante con cada bloque está incluido en el bloque actual y cuando no está incluido en el bloque actual, determinar que el bloque adyacente es un bloque de referencia aludible por el sub-bloque y cuando está incluido en el bloque actual, determinar que el bloque adyacente no es el bloque de referencia; y deducir un candidato de información de predicción del sub-bloque a partir de la información de predicción del bloque de referencia; y cuando el número de candidatos de información de predicción es más pequeño que un número predeterminado, generar uno o más candidatos nuevos sin utilizar la información de predicción del bloque de referencia hasta que el número de candidatos de información de predicción alcance el número predeterminado.
