Abstract:
A projector includes: an image projection unit which projects an image corresponding to image information; an image pickup unit which shoots the image projected from the image projection unit; an image switching unit which switches state of the image based on a predetermined phenomenon; and a projection condition control unit which allows the image projection unit to project a predetermined test image at the time when the image switching unit switches state of the image, and allows the image pickup unit to shoot the projected test image to control projection condition of the image based on the picked-up image result.
