The present invention provides a projector. The projector is provided with: a calibration image information generating part 170; an image projection part 190 to project a calibration image; an image pickup part 180 to pick up the image of an area including the projected calibration image and a projection target through an image pickup face to generate image pickup information; a projection target area information generating part 140 to generate projection target area information showing the coordinates of the four corners of the projection target in an image pickup area based on the image pickup information; a projection area information generating part 150 to generate projection area information indicating the coordinates of the four corners of the calibration image in the image pickup area based on the image pickup information; a correction information generating part 120 to generate image distortion correction information based on the projection target area information and the projection area information; and a distortion correcting part 130 to correct the distortion of the image based on the image distortion correction information.
