ABSTRACT:
A video see through AR system capable of obtaining correct depth information with respect to each pixel representing a two-dimensional image is disclosed so that a portion of imagery which should appear in the background of a final picture may be properly hidden behind imagery which should appear in the foreground of the final picture. A photographing device is provided for obtaining a two-dimensional image of a real object field disposed in conjugate relationship with an observer's eyes. Also provided is a device for measuring distances with respect to each pixel to the real object to be measured. The measured distance is compared with the distance to virtual imagery with respect to each pixel and the pixel which represents the imagery disposed closer to the observer is selected for the formation of combined imagery, which is displayed on the screen of a display device.
