A projector includes a correction value calculator and an image analyzer. The image analyzer acquires a coordinate value of each of a plurality of correction points respectively defining a plurality of correction regions for correcting the shape of a projection video. The correction value calculator calculates, based on a plurality of coordinate values, a correction value for correcting the shape of each of a plurality of divided regions that divide the inside of each of the plurality of correction regions. The correction value calculator specifies a first correction region closest to a first divided region, which is a divided region exceeding a correction limit, among the plurality of correction regions. Then, the correction value calculator smooths a first coordinate value, which corresponds to a first correction point among at least four correction points defining the first correction region, based on the first coordinate value and a coordinate value of each of a plurality of correction points adjacent to the first correction point.
