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: 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.

Abstract: A moving picture coding method includes: performing context adaptive binary arithmetic coding in which a variable probability value is used, on first information among multiple types of sample adaptive offset (SAO) information used for SAO that is a process of assigning an offset value to a pixel value of a pixel included in an image generated by coding the input image (S11); and continuously performing bypass arithmetic coding in which a fixed probability value is used, on second information and third information among the multiple types of the SAO information (S12), wherein the coded second and third information are placed after the coded first information in the bit stream.
