PROBLEM TO BE SOLVED: To improve operability when an image distortion generated by a swing projection is corrected. SOLUTION: The projector comprises an image distortion regulator for regulating a display image signal for displaying an image projected by the projector, in response to values of a horizontal correction parameter corresponding to the image distortion of the horizontal direction; and a vertical correction parameter corresponding to the image distortion of the vertical direction to correct the image distortion generated along at least one direction of the horizontal direction and the vertical direction, by the projector capable of correcting a distortion of the image generated by the swing projection when the image is swing projected in the horizontal direction and the vertical direction to a screen; a two-dimensional input unit for outputting a two-dimensional control signal relating to the horizontal correction parameter and the vertical correction parameter in response to a user's control; and a parameter setter for setting the values of the horizontal correction parameter and the vertical correction parameter in response to the two-dimensional control signal. |
