Abstract

A method is described to display multiple images or pieces of images simultaneously while taking advantage of full color resolution. Digital color images can be stored in a computer in an absolute, or direct, color representation or in a palettized, or indirect, color representation. In an absolute color representation, three numerals are stored, one each for the red gun value, the green gun value, and the blue gun value. To display an image stored in this representation, each value is fed into a digital-to-analog converter that drives the appropriate output gun. If eight-bit values are used to represent each color value, up to 16 million potential colors could be represented with this method.
