Patent ID: 8259235

Claim:
An image processing apparatus, comprising: an image decoding unit that decodes a data stream to generate a first image; and an image adjusting unit coupled to the image decoding unit, the image adjusting unit comprising: a pixel edge determining module that determines an edge luminance parameter according to an initial luminance value of a first pixel of the first image and a plurality of initial luminance values of a plurality of neighboring pixels neighboring the first pixel, and determines an edge chrominance parameter according to an initial chrominance value of the first pixel and a plurality of initial chrominance values of the neighboring pixels; and a first chrominance adjusting module that determines a first weight according to the edge luminance parameter and the edge chrominance parameter, and generates a first adjusted chrominance value by weighted calculating a first predetermined chrominance value and the initial chrominance value of the first pixel according to the first weight.
