A projector includes an image projecting section that is structured to project an image according to an input image, to a virtual projection plane arranged in a predetermined positional relationship therewith, an imaged-information generating section that has an output-image taking section to take an output image projected to a real projection plane and outputs imaged information containing lightness information having a correlation to a lightness in accordance with an image taken, and a distortion correcting section that corrects a distortion, in an output image for the input images caused by an inclination of between the virtual and real projection planes, according to the imaged information. The distortion correcting section has a correcting-image supply section that supplies, to the image projecting section, a correcting image for use in compensating for a distortion of the output image, and an image processing section that determines an amount of a peak shift of from a peak in lightness on the virtual projection plane to a peak in lightness on the real projection plane, according to the imaged information using the correcting image, and previously distorts the input image in a manner compensating for a distortion in the output image, according to the peak shift amount determined. The correcting-image supply section has a correcting-image modifying section that modifies the correcting-image in a manner approximating to an angle of the inclination, an amount of an angular change caused responsive to the peak shift as viewing the peak from the image projecting section.
