A novel 3-D display method using two luminance-modulated 2-D images displayed at different depths

摘要

We have discovered a new 3-D display method which needs only two conventional 2-D displays and a half mirror without any extra equipment. We have developed a prototype 3-D display (28 inches diagonally and 60 cm deep) by applying this method to several pair of planes. The method enables an observer to perceive an apparent 3-D image of continuous depth when the 2-D displays are positioned at different depths, and their luminances are divided between them according to the 3-D image depth. We have also found an extension of this method, in which a DFD image can be perceived as an image protruding outside the region between the two displays when the two display images have opposite signs of luminance difference between an object and the surroundings.
