PROBLEM TO BE SOLVED: To provide a projector capable of accurately acquiring a position of a detection target when an image is projected by correcting distortion of the image.SOLUTION: A projector 100 according to this invention comprises: laser beam generation units 103 to 105 which output laser beams; an image projection unit 109 which comprises a MEMS mirror 109a for scanning the laser beams and projects an image 1a on a table 2; an image processing unit 111 which corrects distortion of the projected image 1a on the basis of information such as a projection angle; a light detection unit 121 which receives the laser beams reflected by a touch pen 2; and a position acquisition CPU 122 which acquires a position of the touch pen 2 on the basis of light reception information on the laser beams received by the light detection unit 121 and information such as the projection angle used to correct the image by the image processing unit 111.SELECTED DRAWING: Figure 2 |
