Abstract

La presente descripción pertenece a un dispositivo de procesamiento de imágenes y método que habilita una reducción en la cantidad de codificación durante la codificación y descodificación. Una unidad de establecimiento de tipo utiliza valores de pixeles de post-desbloqueo, en unidades de LCU, para establecer el tipo de un filtro que es común para componentes Y, Cb, y Cr, y suministra el resultado a una unidad de escritura de sintaxis. Una unidad de ajuste de compensación utiliza los valores de pixeles de post-desbloqueo para establecer una compensación que es independiente para cada uno de los componentes Y, Cb y Cr en unidades de LCU. Una unidad de ajuste de información de control de SAO suministra a la unidad de escritura de sintaxis una compensación o un indicador de fusión que se establece haciendo referencia a la compensación de la unidad de ajuste de compensación. Las presentes descripciones, por ejemplo, pueden aplicarse, a un dispositivo de procesamiento de imágenes.
