FIELD: displaying equipment. SUBSTANCE: device provides correction of entered pixel level according given correction value corresponding to excited mirror from array of excitation mirror. Device has first corrector for gamma correction of entered pixel level, data generator for generation of address data concerning position of entered pixel, memory unit for storage of defined set of corrected data for said excited mirrors and for searching given correction value in a set of corrected values of predefined set using known address data for said entered pixel. In addition device has second corrector for correction of gamma corrected value of entered pixel level using found correction value in order to produce corrected output pixel level. EFFECT: improved image quality. 4 cl, 2 dwg
