ABSTRACT:
Optical properties of a screen on which an image is being projected are considered. A patterned surface is given a predetermined pattern of color pixels whereby a degree of wavelength selectivity is employed to improve the color qualities of the projected image. A system is provided wherein there is a matching of emission characteristics of a projector to the screen's reflective characteristics.
