Abstract

La presente descripción se refiere a un dispositivo y un método de procesamiento de imágenes capaces de suprimir el ruido de bloque. Una unidad de cálculo de ß LUT_entrada y una unidad de limitación calculan el ß LUT_entrada que es el valor introducido a una unidad de generación del parámetro ß existente y una unidad de generación del parámetro ß extendido. Cuando el valor de ß LUT_entrada qp de la unidad de limitación es igual o menor a 51, la unidad de generación del parámetro ß existente calcula el parámetro ß usando la LUT definida en el método HEVC y suministra el parámetro ß calculado a una unidad de determinación del filtrado. Cuando el valor de ß LUT_entrada qp de la unidad de limitación es mayor a 51, la unidad de generación del parámetro ß extendido calcula el parámetro ß extendido y suministra el parámetro ß calculado a la unidad de determinación del filtrado. La presente descripción puede ser aplicada a un dispositivo de procesamiento de imágenes, por ejemplo.
