Abstract
A pixel data correction apparatus, which corrects the value of an input pixel using a predetermined corrected value of its corresponding actuated mirror in an array of M.times.N actuated mirrors, comprises a first corrector for gamma-correcting the value of the input pixel; a memory for storing a predetermined set of corrected values for said M.times.N actuated mirrors; an address data generator for generating address data representing the location of the input pixel; a circuit, responsive to the generated address data for the input pixel, for retrieving a predetermined corrected value from the corrected values of the stored predetermined set; and a second corrector for correcting the gamma-corrected value of the input pixel using the retrieved corrected value to thereby provide a corrected output pixel value.
