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.

Abstract: A device measures a spectral distribution with respect to each of a plurality of color charts, sets default values to band specification data, and computes a camera output signal based on spectral sensitivity of the multiband camera and spectral feature of light from each of the plurality of charts. The device computes a candidate value of a spectral estimation parameter from the measured spectral distribution of each color chart and the computed camera output signal. The device successively varies the band specification data from the default values to make an evaluation function approach a target value, determines a spectral estimation parameter corresponding to the band specification data when the evaluation function reaches the target value. The evaluation function is defined to correlate the measured spectral distribution of each color chart to a spectral estimation value computed from the candidate value of the spectral estimation parameter and the camera output signal.
