Patent ID: 7344252

Claim:
A projector, comprising: a color separation system that receives light emitted from a light source, separates the light into illumination lights of first to third colors, and guides the illumination lights of the first through third colors to first through third optical paths, respectively; first through third light modulation devices to be illuminated, respectively, by the illumination lights of the first through third colors and independently modulate the illumination lights of their respective colors; a distance from the light source to the third light modulation device being different from a distance from the light source to the first light modulation device and a distance from the light source to the second light modulation device; a relay system that is disposed in each of the first and second optical paths or in the third optical path alone; and a correcting system that corrects sizes of illumination areas, for at least the first color and the second color, by adjusting an angle distribution of the illumination lights of the first through third colors that are incident on the first through third light modulation devices, the correcting system being disposed prior to the first through third light modulation devices in the first through third optical paths.
