Abstract

La presente invención se refiere a un aparato de codificación y un método de codificación así como a un aparato de decodificación y un método de decodificación que permiten adquirir datos de imágenes bidimensionales de un punto de vista correspondiente a un método de generación de imágenes de presentación visual predeterminado y datos de imágenes de profundidad sin depender del punto de vista luego de la captación de imágenes. Una unidad de conversión genera, a partir de datos tridimensionales de un objeto de captación de imágenes generados a partir de datos de imágenes bidimensionales de una pluralidad de puntos de vista, datos de imágenes bidimensionales de una pluralidad de puntos de vista correspondientes a un método de generación de imágenes de presentación visual predeterminado y datos de imágenes de profundidad indicativos de una posición de cada uno de los pixeles en una dirección en profundidad del objeto de captación de imágenes. Una unidad de codificación codifica los datos de imágenes bidimensionales y los datos de imágenes de profundidad generados por la unidad de conversión. Una unidad de transmisión transmite los datos de imágenes bidimensionales y los datos de imágenes de profundidad codificados por la unidad de codificación. La presente invención se puede aplicar, por ejemplo, a un aparato de codificación y demás.
