A method of enhancing 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, forming a reference panchromatic image in response to the captured panchromatic pixels, forming an edge map in response to the reference panchromatic image and using the edge map to enhance the full-color image.
