Claim One:
1. A method for sharpening a digital image captured by a digital imaging device, the method comprising: for each pixel X m,n of the digital image: at an edge detector determining an edge parameter E, the edge parameter E providing an indication of whether the pixel X m,n is at an edge of the digital image; at a noise detector determining a noise parameter σ, the noise parameter σ providing an indication of whether the pixel X m,n is a noise in the digital image; at a scaling module determining a scaling factor α m,n based on a combination of the edge parameter E and the noise parameter σ; and at an image sharpening module applying the scaling factor α m,n on a pixel by pixel basis to sharpen the digital image to get a sharpened pixel Y m,n .
