Abstract
Disclosed is a method for sharpening a digital image captured by a digital imaging device, the method comprising, for each pixel Xof the digital image: a) at an edge detector determining an edge parameter E, the edge parameter E providing an indication of whether the pixel Xis at an edge of the digital image; b) at a noose detector determining a noise parameter σ, the noise parameter σ providing an indication of whether the pixel Xis a noise in the digital image; c) at a scaling module determining a scaling factor αbased on a combination of the edge parameter E and the noise parameter σ; and d) at an image sharpening module applying the scaling factor αon a pixel by pixel basis to sharpen the digital image to get a sharpened pixel Y.
