Abstract:
1. A display apparatus comprising: a plurality of optical modulators that display monochromatic images, respectively; an optical system that synthesizes the monochromatic images into a color image; a luminance non-uniformity correction unit that adjusts a correction coefficient according to a luminance to be displayed, and that corrects a luminance non-uniformity in the monochromatic image using the adjusted correction coefficient; and a color non-uniformity correction unit that adjusts a luminance balance among the monochromatic images per pixel or pixel block, thereby correcting a color non-uniformity in the color image, wherein the luminance non-uniformity correction unit adjusts the correction coefficient so as to reduce a correction amount of the luminance non-uniformity if a level of the luminance to be displayed is equal to or higher than a predetermined level, and does not adjust the correction coefficient if the level of the luminance to be displayed is lower than the predetermined level.
