Abstract

La presente descripción se refiere a un aparato y a un método para el procesamiento de imágenes, cada uno de los cuales permite suprimir la reducción de la eficiencia de codificación. En el caso de que sea omitida la transformación primaria como el procesamiento de transformación de un residuo predictivo como una diferencia entre una imagen y una imagen predictiva de la imagen y la transformación secundaria como el procesamiento de transformación de un coeficiente de transformación primaria obtenido al someter al residuo predictivo a la transformación primaria, un interruptor hace que también sea omitida la limitación del ancho de banda de un coeficiente de transformación secundaria obtenido al someter el coeficiente de transformación primaria a la transformación secundaria. La presente descripción, por ejemplo, puede aplicarse a un aparato de procesamiento de imágenes, a un aparato de codificación de imágenes, a un aparato de decodificación de imágenes o similares.
