Abstract

See full text

An image projector includes an image forming element that is illuminated by a light from a light source, a projection optical system that projects a light output from the image forming element, a shifter that shifts the projection optical system with respect to the image forming element so as to shift a projection position, a deforming part that deforms an image formed on the image forming element, and a corrector that corrects a shift direction with the shifter on the basis of a deformation state by the deforming part.
