Abstract

La presente descripción se refiere a un aparato para procesamiento de imagen y un método para procesamiento de imagen capaz de suprimir el deterioro en la calidad de la imagen. El aparato para procesamiento de imagen incluye una unidad de determinación del valor del umbral la cual determina el valor de umbral para identificar una característica de los píxeles adyacentes de un bloque actual en un proceso de predicción intra durante la decodificación de los datos codificados donde los datos de la imagen se codifican de acuerdo con la profundidad de bitios de los datos de la imagen y una unidad del procesamiento de filtrado la cual lleva a cabo un proceso de filtrado sobre los píxeles adyacentes al usar un filtro de acuerdo con la característica de los píxeles adyacentes identificados usando el valor de umbral determinado por la unidad de determinación del valor de umbral. La presente descripción puede ser aplicada a, por ejemplo, un aparato para procesamiento de imagen.
