Abstract
A projector capable of simultaneous or concurrent projection in different positions in the depth direction. The projector includes a plurality of display sections each of which forms a collimated image light ray, a superimposing optical system that superimposes the image light rays having exited out of the plurality of display sections on one another with the image light rays unfocused, a projection optical system that projects an image corresponding to the image light rays superimposed by the superimposing optical system, and a circuit apparatus that causes the image light rays to exit out of local image source areas set in the plurality of display sections to shift a position where the image light rays are superimposed on one another to a plurality of superimposition positions different from one another along an optical axis.
