Abstract:
1. A method for adaptive sharpness enhancement of image data, the method comprising the acts of: receiving image data for a first frame; determining a first signal category for at least one portion of the image data based on the at least one portion of the image data having a thin line; performing linear sharpening enhancement of the image data for the first frame; performing non-linear sharpening enhancement of the image data for the first frame; generating blending parameters, by a controller, based upon the image data of the first frame and the first signal category, the blending parameters corresponding to a proportion of linear sharpened image data and non-linear sharpened image data to be applied to each respective pixel of the image data of the first frame to form an output frame, wherein the non-linear sharpened image data is applied to at least one pixel of the at least one portion of the image data having the first signal category; and generating the output frame by selecting, for each respective pixel of the image data of the first frame, one of the respective pixel of the image data of the first frame, a corresponding linear sharpened pixel, and a corresponding non-linear sharpened pixel based upon the blending parameters, the output frame including at least one first pixel of the image data of the first frame and at least one second pixel selected from one of a linear sharpened pixel and a non-linear sharpened pixel.
