Patent ID: 7303284

Claim:
An image display apparatus for displaying a display image in accordance with input image data of a plurality of colors, to enable an observer to observe the image, comprising: a light source section which is configured to emit illumination light of said each color; a display device which is illuminated by said illumination light and is configured to enable the observer to observe said display image by forming an image in accordance with said input image data of each color to modulate a light amount of said illumination light; a distribution area recognizing section which is configured to specify and recognize an area in which each pixel structuring said image data of each color is distributed in a color space defined by said image data of each color; and a projection condition controlling section which is configured to control a magnification of data conversion of image data used in modulation by said display device and a magnification of light amount control of illumination light emitted from said light source section to make a multiplied value of the magnification of data conversion and the magnification of light amount control equal in each color so that a color distribution of said display image observed by the observer has an appropriate color balance vector having the same direction and a large size as those of an appropriate color balance vector showing a color distribution of an area recognized in said distribution area recognizing section.
