A projector includes: an image signal processing circuit which receives and converts a first image signal to generate a second image signal representing an image to be projected; an image distortion correction unit which corrects the second image signal in response to a correction point on a projected image being changed by an operation done by a user; and an OSD circuit which operates, in response to an image distortion correction process being selected in response to an operation done by the user, to superpose a correction pattern used to allow the user to designate the correction point on the projected image, and thus display the correction pattern and the projected image on a single screen. The OSD circuit includes a switching control unit which switches a color used to display the correction pattern when the image distortion correction process is performed.
