Abstract
A method of producing a display image comprises receiving image information representing an image to be displayed, producing an image formed of a plurality of images of different colors, and projecting the produced image along an optical path. The differently colored images have color intensities related to energy applied to a light source. A level of energy is applied to the light source during production of the image of one color that is different than the level of energy applied to the light source during production of the image of another color.
