<P>PROBLEM TO BE SOLVED: To provide a projector facilitating the adjustment thereof in the case of projecting a large-sized image or projecting a high-definition image. <P>SOLUTION: The projector 1 includes an illuminating device 100; a first image forming means (first image forming unit 100) that emits first image light; a second image forming means (second image forming unit 200) that emits second image light; a polarization/composition optical system (polarizing/compositing prism 50); and a projection optical system 60. The first image forming unit 100 and the second image forming unit 200 are disposed movable on the same plane, in a direction perpendicular to each other within a prescribed extent. By setting the moving amount of the first image-forming unit 100 and the moving amount of the second image-forming unit 200, the aspect ratio of the image corresponding to the first image light emitted from the first image-forming unit 100 and the aspect ratio of the image corresponding to the second image light emitted from the second image forming unit 200 can be set to be within a prescribed range. <P>COPYRIGHT: (C)2009,JPO&INPIT |
