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: 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: generating a predicted block (S6001); calculating a residual block (S6002); calculating quantized coefficients by performing transform and quantization on the residual block (S6003); calculating a coded residual block by performing inverse quantization and inverse transform on the quantized coefficients (S6004); generating a temporary coded block (S6005); determining whether or not an offset process is required, to generate first flag information indicating a result of the determination (S6006); executing the offset process on the temporary coded block when it is determined that the offset process is required (S6012); and performing variable-length coding on the quantized coefficients and the first flag information (S6011).

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.
