Patent ID: 8651667

Claim:
A projector, comprising: a plurality of projection devices which generate images by modulating laser beams in colors of R, G, B with optical modulators and which project the images onto projection surfaces through projection lenses, wherein the images that are projected respectively from said projection devices onto said projection surfaces are tiled into a single image as a whole, wherein a number of G-color laser beam sources is smaller than a number of images projected respectively from said projection devices onto said projection surfaces, wherein said projection devices share said G-color laser beam sources and apply G-color laser beams emitted from said G-color laser beam sources to said optical modulators thereof, wherein said projection devices include: a single first projection device including a G-color laser beam source of said G-color laser beam sources; and a single second projection device other than the first projection device, wherein said first projection device includes a light path switcher for switching a light path of the G-color laser beam emitted from said G-color laser beam source over to said optical modulator thereof or to the second projection device in a time-multiplexed fashion, and wherein said second projection device includes a reflective device for changing a light path of the G-color laser beam supplied from said first projection device to said optical modulator thereof.
