PROBLEM TO BE SOLVED: To allow a projector to correct distortion in an image in correspondence with the shape of a projection plane and to correct distortion in a displayed image on a rugged plane or a projection curved plane. SOLUTION: This projector consists of a video input section 1 that receives an original image, a projection area acquisition section 3 that calculates an azimuth angle, a tilt angle and a distance of a projection plane from a normal vector of the projection plane to acquire a three-dimensional shape of the projection plane, a video correction section 2 that corrects tilting and magnification/ reduction to the input original image corresponding to the shape of the projection plane, and a video output section 4 that projects and outputs the corrected image. |
