摘要：
An image projection apparatus of the present invention projects a corrected image according to a projection surface, and includes: an imaging unit for capturing a projected image; a correction parameter calculation unit for calculating a correction parameter, on the basis of the captured image, for correcting an image distortion caused by the projection surface; a correction unit for generating a corrected image by correcting the image using the correction parameter; a reproduction level calculation unit for calculating a reproduction level of the corrected image relative to the original image; an image generation unit for generating a guidance image regarding the reproduction level; and a control unit for controlling projection of the guidance image.
