Abstract
A method of sharpening a full-color image of a scene includes capturing an image of the scene using a two-dimensional sensor array having both color and panchromatic pixels; forming the full-color image in response to the captured color pixels and forming a reference panchromatic image in response to the captured panchromatic pixels; forming a high-frequency panchromatic image from the reference panchromatic image; and providing a sharpened full-color image in response to the high-frequency panchromatic image and the full-color image.
