Abstract
The present invention is applied to a projector that comprises a plurality of projection devices which generate images by modulating laser beams in the colors of R, G, B with optical modulators and which project the images onto projection surfaces through projection lenses, wherein the images projected respectively from said projection devices onto said projection surfaces are tiled into a single image as a whole. In the projector of the present invention, the number of G-color laser beam sources is smaller than the number of images projected respectively from said projection devices onto said projection surfaces; and 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.
