PROBLEM TO BE SOLVED: To allow quick and reliable detection of an image for adjustment on a projection surface in a projector which projects the image for adjustment on the projection surface to perform correction and the like on the basis of the image for adjustment.SOLUTION: A projector includes a projection unit 101 which projects an image on a projection surface, a projection control unit 121 which makes the projection unit 101 project a correction pattern 177 including a first pattern and a second pattern, and a correction control unit 122 which detects the first pattern and the second pattern included in the projected correction pattern to correct distortion of the projected image. The correction control unit 122 detects the second pattern projected on a screen SC and detects the position of the first pattern on the basis of the position of the detected second pattern. |
