Abstract:
There is disclosed a system and method for enhancing gray scale output on a color display. Various gray intensities are mapped based on an image made of various shades of gray so that a viewer perceives a depth of gray levels beyond those available in gray scale from the color display. Pseudo shades of gray are displayed between the levels of true gray that typically are displayed in order to provide a smoother transition between the levels of true gray that are displayed.
