Abstract
A projector includes a projection optical system adapted to project an image modulated by a light modulation device on a projection surface, a guide display section adapted to dispose a plurality of guides used for setting a black level area, which is an adjustment target area of a black level, on the projection image, and then displays the guides in the case in which projection is performed on the projection surface so that the projection images from a plurality of projectors including the present projector partially overlap each other, an input operation section adapted to receive a position adjustment operation of each of the guides, and a black level area setting section adapted to set the black level area, which is the adjustment target area of the black level, based on an arrangement of the guides.
