Abstract

Un método de decodificación de imágenes capaz de decodificar apropiadamente una imagen por una configuración sencilla es un método de decodificación de imágenes para decodificar una imagen codificada incluida en un flujo de bits cuadro por cuadro, y comprende: decodificar aritméticamente un cuadro a ser decodificado (S101); determinar si el bloque a decodificarse se ubica al final de una porción o no (S103); cuando se determina que el cuadro a decodificarse no se ubica al final de porción, determinar si el bloque a decodificarse se ubica al final de una subunidad que es una unidad constituyente de la imagen diferente de la porción (S105); y cuando se determina que el cuadro a decodificarse se ubica al final de la subunidad, realizar un procesamiento de terminación de decodificación aritmética al decodificar aritméticamente un bit sub-final(S106).
