<p>A method for interpolating pixel colors in a digital system is provided. The method comprises obtaining at least two pixels of a first color having a first level of similarity, wherein the at least two pixels are positioned adjacent a first pixel to be restored; calculating average values of the two pixels for the first color; restoring the value of the at least two pixels for the first color; and restoring a value associated with a second color for the at least two pixels by an interpolation method using a gradient of a brightness.
