Abstract
A display apparatus is provided which, when projecting a video onto a curved surface of an object for display, can realize an undistorted display of the video. The measuring means outputs the distance information representing the distance to the object. Based on the distance information produced by the measuring means, the curved surface contour is detected with high precision. According to at least the detected curved surface contour distortions, pixels of the display image are unevenly rearranged to correct the video information before it is output. This arrangement realizes an undistorted display of video when the video is projected onto the curved surface of the object.
