An interactive projector includes a projection section, a first detection light irradiation section and a second detection light irradiation section, an imaging section, and a position detection section adapted to detect a position of the pointing element based on an image, which is taken by the imaging section and includes the pointing element. The first and second detection light irradiation sections are disposed so that at least one of the following (i) and (ii) becomes higher than a threshold value: (i) a first contrast between the pointing element in a first image in a case in which the detection light is emitted only from the first detection light irradiation section and the projected screen, and (ii) a second contrast between the pointing element in a second image in a case in which the detection light is emitted only from the second detection light irradiation section and the projected screen.
