Title: PROJECTOR AND METHOD FOR CONTROLLING PROJECTOR
Abstract:
A projector 1 equipped with a plurality of projection lenses 125-128 to project images, the projector comprising: light sources 101-103; an optical modulator 113 that modulates light generated by the light sources with a video signal; a plurality of optical paths 114-119 that introduce modulated image light into the plurality of projection lenses 125-128; and an optical path switching unit (control device 100) that selects an optical path to a prescribed projection lens from among the plurality of optical paths and switches to the selected optical path. The optical path switching unit 100 carries out time-divided switching to switch the optical paths in accordance with the timing used for modulation by the optical modulator 113, and projects the modulated image light sequentially from the plurality of projection lenses 125-128.
