Method and apparatus for reducing visibility of damping wires in aperture grill display tubes

Apparatus for correcting artifacts on the screen of a display device, comprising:

• a sensor device for locating said artifacts on said screen and responsively generating amplitude values of the area of said screen immediately adjacent said artifacts, wherein said artifacts may include at least one damping wire shadow that is visible on said screen,
• a processor for receiving said generated amplitude values and responsively calculating correction values, said correction values being converted into video values which are alternately and sequentially stored in a plurality of display lists along with corresponding location addresses;
• and
• a compensator device coupled to said processor for utilizing said correction values for reducing the visibility of said artifacts on said screen of said display device, said display device comprising a cathode ray tube.
