Abstract
La presente divulgación pertenece a un dispositivo de procesamiento de imágenes, un método de generación de flujo de bits, un método de generación de datos de coeficiente y un método de generación de coeficiente de cuantificación que hacen posible suprimir una reducción en eficiencia de codificación. La presente divulgación, al codificar una imagen, genera una bandera de salto de transformada que es información de bandera que indica, para cada componente, si saltarse el procesamiento de transformada para transformar un residual entre la imagen y una predicción de imagen de la imagen en datos de coeficiente; codifica la bandera de salto de transformada; genera datos codificados de la bandera de salto de transformada; y genera un flujo de bits que incluye los datos codificados generados de la bandera de salto de transformada. La presente divulgación puede aplicarse 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 método de generación de flujo de bits, un método de generación de datos de coeficiente, un método de generación de coeficiente de cuantificación o similares.
