Patent ID: 8305395

Claim:
A method for producing images in an imaging system having a light engine with an array of individually addressable pixels for modulating light from a light source generating light beams of three primary colors and at least one secondary color, comprising: using a light sensor, sensing actual hue values of the light beams at least for the at least one secondary color; receiving input image signals from an image source, the input image signals including vector image input components for displaying images using the three primary colors; using circuitry, transforming the vector image input components into vector image output components of output image signals for displaying images using the light beams of the three primary colors and the at least one secondary color, the transforming including: determining which two of the three primary colors have hue values between which the sensed actual hue value of the at least one secondary color lies; generating a vector image output component for the at least one secondary color from the vector image input components of the determined two primary colors; and generating vector image output components for the determined two primary colors from the vector image input components of the two primary colors adjusted for the vector image output component generated for the at least one secondary color; and addressing the pixels of the light engine for modulating the light beams to produce the images using the vector image output components of the output image signals.
