Abstract
A projector is disclosed. The projector divides image data, which should be displayed, into a plurality of quadrilateral regions, displays the vertexes of the divided quadrilateral regions to be superimposed on the image data, causes a user to select one of the displayed vertexes as a selected control point, causes the user to move the selected control point, deforms the quadrilateral regions including the selected control point before the movement as one of the vertexes into a shape including, in vertexes, the moved selected control point, and corrects image data corresponding to the quadrilateral regions before the deformation to be fit in the deformed quadrilateral regions.
