Abstract
An image projection apparatus includes a light modulation element, and a pixel shift unit configured to shift an optical path of light from a pixel in the light modulation element and to shift a position on a projection surface of a projection pixel formed on the projection surface by a projection optical system with the light. The pixel shift unit includes an optical element configured to shift the optical path in one direction among directions orthogonal to an optical axis from the light modulation element to the projection optical system, and a rotating unit configured to change the one direction by rotating the optical element around the optical axis.
