Abstract: Generating luminance uniformity in a rear projection display system is provided. The method comprises calculating luminance generated by a projector on a rear projection screen relative to a design eye position in front of the screen. A baseline luminance is determined for each primary color according to the luminance. Luminance of all locations on the screen is corrected toward the baseline. Correction is allocated between an optical filter and electronic correction. Luminance is measured at calibration points on the screen. The electronic correction for a color image is adjusted according to the allocation and the luminance at the calibration points to produce a corrected color image for projection from the projector. The corrected color image is projected from the projector and through the optical filter. The optical filter is configured to dim specified areas within the corrected color image according to the allocation.
