Abstract
A projector includes a projection lens, a distance information acquiring section that acquires distance information relating to the distance from the projector to a projection surface, a first imaging section that captures an image of the projection surface, a second imaging section that has an angle of view wider than the angle of view of the first imaging section and captures an image of the projection surface, and a control unit. The the second imaging section is disposed in a position closer to the optical axis of the projection lens than the first imaging section. The control section causes the first imaging section to capture an image in a case where the distance from the projector to the projection surface is greater than or equal to a predetermined threshold and the second imaging section to capture an image in a case where the distance is smaller than the threshold.
