Abstract

La presente descripción se refiere a un aparato y un método para codificación de imagen capaz de suprimir la reducción en la eficiencia de la codificación. El aparato para codificación de imagen incluye; una unidad de codificación que codifica los datos de la imagen configurada por una pluralidad de capas; una unidad de generación de la información relacionada con la predicción inter capas que genera la información relacionada con la predicción inter capas de la sección actual en un caso donde la capa de la sección actual es una capa de mejoramiento, y el tipo de la sección de la sección actual es una sección P o una sección B, y una unidad de transmisión que transmite los datos codificados de los datos de la imagen, generados por la unidad de codificación y la información relacionada con la predicción inter capas, generada por la unidad de generación de la información relacionada con la predicción inter capas. La presente descripción, por ejemplo, puede ser aplicada a un aparato para procesamiento de imagen tal como un aparato para codificación de imagen que codifica de forma escalable los datos de la imagen o un aparato para decodificación de imagen que decodifica los datos codificados adquiridos al llevar a cabo la codificación escalable de los datos de la imagen.
