    • An apparatus for processing an image signal and a method therefor are provided to embody the sharpness of an image by previously extracting an edge part of the image and selectively filtering only the edge part. A digital image processing unit(30) receives an image signal decoded by a decoder, and performs a digital image process of the received image signal. The digital image processing unit(30) includes an edge detecting unit and a filtering unit. The edge detecting unit detects pixels corresponding to an edge from the inputted image. The filtering unit filters only the pixels detected as the edge by the edge detecting unit.
    • 提供一种用于处理图像信号的装置及其方法,以通过预先提取图像的边缘部分并且仅选择性地仅过滤边缘部分来体现图像的清晰度。 数字图像处理单元(30)接收由解码器解码的图像信号,并对所接收的图像信号执行数字图像处理。 数字图像处理单元(30)包括边缘检测单元和滤波单元。 边缘检测单元从输入图像检测与边缘对应的像素。 滤波单元仅对由边缘检测单元检测为边缘的像素进行滤波。
