Abstract:
A projector includes: an operation unit which receives operation by a user; a projection unit which projects light corresponding to an image signal; and a light intensity control unit which controls light intensity of the light projected by the projection unit. The light intensity control unit controls the light intensity in the order of reception of plural operations received by the operation unit from the user.
