<p>PROBLEM TO BE SOLVED: To dividedly project a video in such a manner as to avoid an area not suited for projection, regardless of a type of the area.SOLUTION: A video projection device first generates a range of an area on which a user does not want to project a video as division position information by an operation of the user. Image deformation is performed on the basis of the generated division position information. At that time, the video projection device uses operators for implementing a plurality of four-point specified deformation processes as coordinate transformation operators, where a line segment representing a division position is made to be a black area after transformation. For other areas, the video projection device acquires pixel values of coordinates included in a square after the transformation by the four-point specified deformation process using pixel values of coordinates that are present in the square before the transformation.</p> |
