projecting a correction image having a rectangular shape in which a plurality of correction points is arranged on a first side out of four sides of the rectangular shape on a projection surface;
receiving an operation of moving a first correction point included in the plurality of correction points in a first direction; moving another correction point than the first correction point out of the plurality of correction points in a second direction opposite to the first direction when an amount of movement in the first direction of the first correction point by the operation is larger than a threshold value; and
