8Color Processing in the Projector

The color processing in the projector provides several functions. The first is a means to calibrate the projector so that the image on the screen matches the Reference Projector primaries, white point and peak white luminance. This calibration compensates for differences in the spectral characteristics of optical components in the projector, including the lamp, reflectors, prism and projection optics. It also compensates for environmental characteristics like discolorations introduced by the portal glass or the screen itself.

This calibration is performed by measuring the luminance and chromaticity coordinates of an internally generated white field test pattern, along with the chromaticity coordinates of red, ...
