Processing a digitized image signal includes selectively adjusting interpolated color values on the basis of correlations between pre-identified reference patterns of values and the patterns of values within the neighborhoods in which the interpolated color values reside. The reference patterns may be various possible combinations of a high reference value and a low reference value within a selected neighborhood configuration. When minimum and maximum color values are used as the reference values, the reference patterns are representative of the various maximum luminous gradient possibilities within the selected neighborhood configuration.
