Abstract:
A processing system for a digital display system that receives a gamma-corrected, color component, video input signal for display on a spatial light modulator, comprising:an array of deformable mirror devices, each mirror device being associated with at least one electrode, each mirror device being deflectable between a first orientation in which light incident on the mirror device is reflected along an ""ON"" direction towards a display and a second orientation in which light incident on the mirror device is reflected along an ""OFF"" direction dependent on electrical signals applied to the associated electrode;the processing system comprising:an analog-to-digital converter for converting said input signal to component pixel data;a colorspace conversion processor for converting said component pixel data to RGB (red, green, blue) data;a de-gamma processor for removing all or part of the gamma-correction of said pixel data to match the data to the form of the spatial light modulator; anda display memory for receiving processed pixel data and for formatting said pixel data into bit-planes for display by said spatial light modulator.
