Patent ID: 7018045

Claim:
An image display apparatus, comprising: first image light generation means for generating image lights individually corresponding to a plurality of color components, which form a single first color component group; and display image light generation means for synthesizing the image lights of the individual color components generated by said first image light generation means to generate a first display image light; said first image light generation means setting color component values of the individual color components of the first color component group, so that the first display image light may be generated with a chromaticity point and a luminance equal to those of a second display image light, wherein the second display image light includes synthesized image lights individually corresponding to color components of a second color component group whose color components in combination are different from those of the first color component group, and wherein said first image light generation means generates image lights individually corresponding to the color components, of the first color component group based on the set color component values; second image light generation means for generating image lights individually corresponding to the color components, which form said second color component group; said display image light generation means synthesizing the image lights of the individual color components generated by said second image light generation means to generate the single second display image light; and switching means for switching the image lights to be synthesized by said display image light generation means between the image lights generated by said first image light generation means and the image lights generated by said second image light generation means based on data provided through a predetermined image pattern input to said switching means.
