Abstract

La presente descripción se refiere a un dispositivo y método de procesamiento de imágenes que hacen posible mejorar la eficiencia del procesamiento en codificación y descodificación. El tipo E0 en una LCU (115) y un coeficiente de la misma se determinan por el lado de codificación. El coeficiente tipo E0 se envía al lado de descodificación cuando el coeficiente ya se encuentra en LCU (III), y se almacena en una memoria intermedia de EO de un filtro de compensación adaptable en el lado de descodificación. Por lo tanto, con respecto a la LCU (115) en el lado de descodificación, el coeficiente tipo E0 puede copiarse de la memoria intermedia de EO y utilizarse sin que se envíe. De esta manera, el parámetro del filtro de compensación adaptable que se transfirió de manera convencional de proceso simple en el encabezado de una trama se envía secuencialmente en el encabezado de la LCU para cada LCU. La presente descripción puede aplicarse, por ejemplo, a un dispositivo de procesamiento de imágenes.
