IPC: G03B21/14
Filed: 2000-07-27
Abstract: PROBLEM TO BE SOLVED: To provide a projection type grid-shaped display device that can correct the distortion of a projected video caused when a video image is projected onto a screen while a projection optical axis is obliquely tilted. SOLUTION: The projection type grid-shaped display device 10 has a device main body 12 and a distortion correction device 14. The distortion correction device 14 is provided with a test video display means 16, a coordinate entry device 18, a pointer 20 and a distortion correction circuit 22. The device main body projects the video displayed on a grid-shaped video display body onto a screen through a projection lens as a radiation projection light and the screen displays the projected vide. The distortion correction device corrects distortion in the projected video when the video is projected on the screen while the projection optical axis is obliquely projected. A test video means uses e.g. a rectangle image for a test video and allows the screen to display the test projection video.  The coordinate entry device enters coordinates as four corners of a rectangle not distorted corresponding to coordinates at four corners of a distorted rectangle. The pointer shifts the four corners of the distorted rectangle to the coordinates at the four corners of the rectangle not distorted. The distortion correction circuit corrects the distortion of the projected video on the basis of the relation between the coordinates at four corners of the distorted rectangle and the coordinates at four corners of the rectangle not distorted.
