Abstract
Provided are: a video-image transformation unit performing video-image transformation to a video image inputted from outside; a video-image projection unit projecting, onto a video-image projection surface, a video image video-image-transformed by the video-image transformation unit; an image sensor acquiring a projected range of the projected video image projected by the video-image projection unit and an image obtained by photographing a corrected object; and a processor performing a calculation processing using the image photographed by the image sensor. The processor generates correction data from the projected range of the projected video image by the video-image projection unit and the image of the corrected object that are photographed by the image sensor, the video-image transformation unit performs video-image transformation based on the correction data generated by the processor so that the projected range of the projected video image by the video-image projection unit becomes rectangular on the video-image projection surface.
