Abstract

Image display apparatus () comprising projector means (), a light source (), at least one primary modulator () for modulating light, an auxiliary modulator () for modulating the light modulated by the primary modulator (), optical means () for relaying the light modulated by the primary modulator () to the auxiliary modulator (), and control means () for controlling the primary modulator () and the auxiliary modulator (), characterized in that: the primary modulator () comprises a first array of pixels, and the auxiliary modulator () comprises a second array of pixels; each pixel in the first array of pixels of the primary modulator () is controlled by the control means () as a function of video input data for each pixel in the first array of pixels; and each pixel in the second array of pixels of the auxiliary modulator () is controlled by control means () as a function of video input data for each equivalent pixel in the second array of pixels, and each adjacent pixel in the second array of pixels.
