Patent ID: 8005313

Claim:
An edge enhancing device applying to an image processing device, comprising: an edge detector, disposed within the image processing device, for determining aft single edge direction of an image region corresponding to a target pixel, wherein the image region constitutes by a pre-determined number of pixels surrounding the target pixel; and a pixel value determining module, disposed within the image processing device, coupled to the edge detector, to obtain an original pixel value of the target pixel according to the position of the target pixel and a plurality of reference pixel values of a plurality of reference pixels for enhancing the edge according to the single edge direction, and performing a weighted average operation to multiply the original pixel value and the plurality of reference pixel values by different weights separately to generate a high-frequency information of the target pixel, and generate an adjusted pixel value of the target pixel according to the high-frequency information and the original pixel value; wherein the image processing device is used for executing image processing processes.
