Patent ID: 7590302

Claim:
A system comprising: an edge enhancer to enhance a portion of image data with enhancement data determined from the image data, where the image data corresponds to an edge of an image, and where the enhancement data comprises an offset value, the edge enhancer comprising: a receiver to receive the image data; a determining circuit to determine the enhancement data from the image data where the determining circuit determines the offset value from a first differential signal and a second differential signal, where the offset value comprises an enhancement luminance amplitude and an enhancement chrominance vector, wherein the enhancement luminance amplitude is determined according to the following equation: Offset l =DFS l ×MIN(|2 nd Diff l |,|1 st Diff l |)−2×2 nd Diff l where Offset l is the enhancement luminance amplitude, 1 st Diff l is the first differential signal, and 2 nd Diff l is the second differential signal, and where the first differential signal is determined from a first and a third portion of the image data and the second differential signal is determined from the first, a second, and the third portions of the image data; and an enhancing circuit to enhance the portion of the image data with the enhancement data; and a panel to display the enhanced image data.
