Abstract:
A projector includes a lens driving unit that drives a lens unit including a projection lens; a reception unit that receives instruction information that is input; and a control unit that controls a lens shift by the lens driving unit based on lens shift instruction information with respect to the projection lens, which is received by the reception unit, in such a manner that zoom, which is performed by the lens driving unit based on zoom instruction information adjusting angle of view with respect to the projection lens, is performed in a predetermined state for a first image which is projecting in a state that a central position of the first image is different from a basis position of the zoom.
