Patent ID: 8382297

Claim:
A method for combining non-visible data and visible data for a projector enabled to project visible images and non-visible images, the method comprising, receiving, at an image generator, visible bits representative of said visible images to be projected by the projector in a visible light spectrum said visible bits comprising red, green and blue color bits; receiving, at said image generator non-visible bits representative of said non-visible images to be projected by the projector in a non-visible light spectrum; and, replacing, at said image generator, a portion of said visible bits with at least a portion of said non-visible bits in video data comprising frames, each said frame comprising said red, green and blue color bits, by alternating replacing one of said red, green and blue color bits with most significant non-visible bits and least significant non-visible bits in successive frames of said video data, such that said visible images and said non-visible images can be co-projected by the projector upon processing said video data.
