Abstract
A projector includes: a light source which emits light containing visible light and infrared light; a light time division unit which divides light emitted from the light source into one or more visible lights having different wavelength ranges and one or more infrared lights having different wavelength ranges in a time-division manner; a light modulation element which time-sequentially modulates the plural lights separated by the light time division unit and having different wavelength ranges; and a projection unit which projects and displays the light modulated by the light modulation element on a projection-receiving surface. A plurality of images containing a visible image produced by the one or more visible lights and an infrared image produced by the one or more infrared lights are displayed on the same projection receiving surface.
