Abstract

La presente divulgación pertenece a un dispositivo de procesamiento de imágenes y un método de procesamiento de imágenes que posibilitan la supresión de una reducción en la eficacia de codificación. Cuando es verdadera una bandera de salto de conversión de al menos un componente entre componentes válidos en la codificación de imágenes, se omite la codificación de la información de control de conversión secundaria que es información de control acerca de la conversión secundaria. Cuando son falsas las banderas de salto de conversión de todos los componentes, se codifica la información de control de conversión secundaria. La presente divulgación es aplicable a, por ejemplo, un dispositivo de procesamiento de imágenes, un dispositivo de codificación de imágenes, un dispositivo de decodificación de imágenes, un dispositivo de transmisión, un dispositivo de recepción, un dispositivo de transmisión/recepción, un dispositivo de procesamiento de información, un dispositivo de formación de imágenes, un dispositivo de reproducción, un dispositivo electrónico, un método de procesamiento de imágenes, un método de procesamiento de información, etc.
