Abstract

An image projection apparatus includes a light modulation element, a pixel shift unit that includes an optical element 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 projected pixel formed on the projection surface by a projection optical system with the light, and an attachment portion to which the pixel shift unit is attached. The optical element shifts the optical path by a shift amount in accordance with an attachment angle of the pixel shift unit relative to a plane orthogonal to an optical axis from the light modulation element to the projection optical system. The attachment portion is configured to select a plurality of angles for the attachment angle.
