Abstract
A processing system for a spatial light modulator in the form of an array of deformable mirror devices receives a gamma-corrected, color component, video input signal. The input signal is converted to pixel data which is then converted to RGB data. A de-gamma processor removes all or part of the gamma-correction of the pixel data to match the data to the form of the spatial light modulator.
