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: 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.
