Projector, and black level area setting method for projector

A first projector adapted to constitute a part of a system adapted to perform projection on a projection surface so that projection images from a plurality of projectors including the present projector partially overlap each other, the first projector comprising:

• a projection optical system adapted to project the projection image, which is modulated by a light modulation device, on the projection surface;
• a guide display section adapted to display a guide used for setting a black level area, which is an adjustment target area of a black level, on the projection image;
• an operation section adapted to receive a position adjustment operation of the guide;
• a black level area setting section adapted to set the black level area based on an arrangement of the guide on which the position adjustment operation by the operation section has been performed;
• and
• a black level adjustment section adapted to correct a brightness of the black level area and a color of the black level area,
• wherein the black level area does not overlap with a projection image of another projector of the plurality of projectors.
