Abstract

Se provee un método de codificación de imágenes que usa codificación aritmética y que comprende el siguiente paso de codificación del primer indicador (S701) para la codificación aritmética de un primer indicador (greater1_flag) que indica si un valor absoluto de un coeficiente de destino de procesamiento incluido en el bloque de coeficientes de destino es o no mayor que 1; y un paso de codificación del segundo indicador (S702) para efectuar la codificación aritmética de un segundo indicador (greater2_flag) que indica si el valor absoluto del coeficiente de destino de procesamiento es o no mayor que 2. En el paso de codificación del primer indicador y en el paso de codificación del segundo indicador, si se determina si existe un coeficiente, el valor absoluto del cual excede un umbral en el bloque de coeficientes inmediatamente anterior al bloque de coeficientes del objeto del procesamiento (S711), y dependiendo de los resultados de la determinación, el contexto utilizado en la codificación aritmética del primer indicador y el segundo indicador cambia (S712).
