Method and apparatus for adaptively sharpening local image content of an image

摘要

Briefly, in accordance with one embodiment of the invention, a method of sharpening an image includes the following. A crispening parameter is adaptively computed for a local region of a captured image based, at least in part, on a measure of the local contrast and the local brightness. A kernel is applied to the local region of the captured image using the adaptively computed crispening parameter.
