ABSTRACT:
An apparatus, methods, and systems for multi-color projection or display for video or lighting applications. One aspect of the present invention comprises an algorithm for utilizing at least four primary light sources to represent a projected pixel color. The algorithm and associated system can be applied to both a natively monochromatic light source or traditional light sources filtered for their colored components. The algorithm can be used for either color sequential or parallel modes of operation. The algorithm takes input pixel data represented in a universal color coordinate system, performs a color transform, and disperses the results among parallel display devices or sequentially to a single device such that each pixel is presented by the combination of four or more primaries.
