Abstract

[Problema] Proporcionar un aparato de procesamiento de imagen y un método de procesamiento de imagen. [Solución] Se proporciona un aparato de procesamiento de imagen. El aparato de procesamiento de imagen incluye una unidad de decodificación configurada para generar una imagen decodificada decodificando un flujo codificado, una unidad de determinación configurada para adoptar un límite de bloque de la imagen decodificada como un objetivo y determinar la necesidad de aplicación de filtro de desbloqueo con respecto a componentes de diferencia de color de la imagen decodificada con base en la fuerza del límite que se calcula usando un parámetro relacionado a la diferencia de color relacionado con una diferencia de color, y una unidad de filtración configurada para aplicar un filtro de desbloqueo a componentes de diferencia de color de píxeles localizados en una cercanía del límite del bloque con base en un resultado de determinación de la necesidad de aplicación del filtro de desbloqueo.
