Abstract
Detection accuracy of a distance between a tip of a pointing element and a screen is to be improved. An interactive projector includes a projection unit, a plurality of cameras, and a position detection unit that detects a three-dimensional position of the pointing element with respect to the projected screen based on a plurality of images including the pointing element of which the image is captured by the plurality of cameras. When a direction separated from the projected screen is defined as a Z direction, the second camera is arranged at a position nearer the projected screen than that of the first camera in the Z direction.
