Patent ID: 7050074

Claim:
An image display apparatus, comprising: an image processor for outputting image data including plural color component data, wherein the plural color component data includes red, blue and green color component data; a gain corrector for correcting chromaticity levels of the image data output by the image processor; and an image display device having pixels each emitting a plurality of colored light rays for forming a color image in accordance with the corrected image data corrected by the gain corrector, wherein the gain corrector corrects a respective level of the red and blue color component data applied to each respective pixel in the image display device based on measured luminance levels at each respective pixel such that, when image data representing an image of a uniform color are output from the image processor, a difference in chromaticity of light exiting from the pixels due to characteristic differences between the pixels of the image display device is reduced without making uniform a luminance of the light exiting from the pixels of the image display device; and the gain corrector is configured to use the measured luminance level of green at each pixel as a reference level to reduce the difference in the chromaticity at each pixel.
