Projector and control method for the projector

摘要

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.

1. A projector comprising:
a first display control unit that divides image data, which should be displayed, into a plurality of quadrilateral regions and that performs control to display vertexes of the quadrilateral regions to be superimposed on the image data; an operation receiving unit that receives input operation; a selecting unit that causes a user to select one of the vertexes as a selected control point; a moving unit that causes the user to move the selected control point on the basis of the input operation; and an image correcting unit that deforms the quadrilateral regions including the selected control point before the movement as one of the vertexes into a shape including, in vertexes, the selected control point moved by the moving unit and corrects image data corresponding to the quadrilateral regions before the deformation to be fit in the deformed quadrilateral regions.
