1. A method of enhancing an input digital image having color features comprising: converting said input digital image to a binary image of first and second type pixels such that pixels of said input digital image that define said color features are substantially converted to said first type pixels of said binary image; changing the resolution of said binary image to derive a modified binary image; and selectively inserting colors into pixels of said modified binary image to produce an output digital image having modified color features that differ in resolution with said color features of said input digital image.
