Patent ID: 7364305

Claim:
A projector, comprising: a light source to emit light containing a visible region of light; a color separation system to separate a luminous flux emitted from the light source into a plurality of kinds of colors of light different in exit direction; a light modulation system to modulate the plurality of kinds of colors of light separated at the color separation system and forming first optical images; and an anamorphic projection system to convert the first optical images formed at the light modulation system into second optical images having a desired aspect ratio thereby projecting same; the light modulation system including a light valve including a plurality of sub-pixels provided corresponding to the plurality of kinds of colors of light separated at the color separation system and micro-lenses to collect the plurality of kinds of separated colors of light and allowing the plurality of kinds of separated colors of light to exit to corresponding ones of the sub-pixels, the sub-pixels being formed in a form to include the color of light focused on the sub-pixel by the micro-lens; and the color separation system being structured to separate a luminous flux emitted from the light source into four kinds of colors of light, the light modulation system including a first light valve to modulate any two kinds of colors of light of among the four kinds of color of light separated by the color separation system, and a second light valve to modulate other two kinds of colors of light, a color combining system being provided between the light modulation system and the anamorphic projection system that combines together the four kinds of colors of light modulated by the first light valve and second light valve.
