Abstract
An image projection apparatus includes a projection unit that projects a pattern image on a projection surface; an image capturing unit that captures the projected pattern image; and a corrector that corrects the captured image so that an imaging distortion caused due to image capturing and a projection distortion caused due to projection are corrected. The projection unit projects the corrected captured image at a predetermined position on the projection surface.
