1. A method for determining that an image element is likely to be self-luminous, the method comprising: a. determining image element characteristics; b. comparing the characteristics of said image element to those for known self-luminous elements wherein said comparing comprises at least one act taken from the set consisting of: (i) comparing the proximity of said image element to image boundaries with the proximity of known image elements to their boundaries, (ii) comparing the color characteristics of said image element to characteristics of a known illuminant, and (iii)comparing the luminance characteristics of said image element to characteristics of known self-luminous elements; c. assigning a self-luminosity weight factor to said image element; and d. estimating a color balance correction for at least a portion of said image wherein said correction is based on said weight factor
