摘要：
An apparatus for image processing includes: an edge detection module, for performing an image edge detection for each pixel in an original image data and generating at least one edge detection result for a target pixel in the original image data; a step-wise gain controlling module, coupled to the edge detection module, for determining at least one gain coefficient of the target pixel according to the edge detection result; and a calculation module, coupled to the step-wise gain controlling module, for adjusting an original gray value of the target pixel to generate an output gray value of the target pixel according to the gain coefficient.
