Abstract

An image projection apparatus has: a deformable mirror configured from a plurality of micromirrors; an optical system to form, on the deformable mirror, an intermediate image of an image to be formed based on image data outputted from an image output unit; an imaging device; an image comparator; and a controller for controlling the deformable mirror. The image comparator performs comparison between the image data outputted from the image output unit, and image pickup data of a projection surface, the image of which is picked up by the imaging device, and obtains blur correction amount of the image on the projection surface by each divided region of a projection image, and based on the blur correction amount of the image on the projection surface, said blur correction amount having been obtained by each region, the controller moves, corresponding to the blur correction amount, the micromirrors corresponding to respective regions.
