Abstract:
A digital color image data (CID) improving apparatus, comprising:an input that is configured to receive and propagate, in series or parallel, at least three separate and distinct color signals, each color signal being comprised of digital color image data for only one color and the color of each of said three color signals being different;filter logic coupled to said input that filters the color signal of the color to which the human eye is most sensitive and does not filter one of the other color signals;said filter logic being further configured to receive the digital color image data of the color signal to be filtered in a stream of color image data values, and functioning to compare a received color image data value to a value derived from neighboring data values of the same color and to adjust the magnitude of the received color image data value if predefined criteria are met; andan output coupled to said filter logic that outputs the filtered color signal along with the unfiltered color signal.
