ABSTRACT:
This invention discloses an image processing apparatus comprising a filter module, an edge detection module, and a processing module. According to where each pixel locates in an image block, the filter module is used to perform the smooth processing on each pixel to generate a second gray level corresponding to each pixel. The edge detection module is used to determine each pixel to be an edge pixel or a non-edge pixel according to the first gray level and the second gray level of each pixel. The processing module is used to calculate a third gray level of each edge pixel according to a weight, the first gray level, and the second gray level; to calculate a fourth gray level of each non-edge pixel according to the weight, the first gray level, and second gray level, and to output all of the third and fourth gray levels.
