1. A method of improving an image separable into at least a first color component and a second color component, the first color component having pixels located at a plurality of first pixel locations and a second color component having pixels located at a plurality of second pixel locations, said method comprising the steps of: noise filtering the first color component using pixel values of the first color component for providing a noise-filtered color component having filtered pixel values at the plurality of first pixel locations, and adjusting the filtered pixel value of at least one first pixel location of the noise-filtered color component using information indicative of a difference in pixel values of the second color component at the second pixel locations adjacent to said at least one first pixel location.
