54.1: A Novel Direct‐Vision 3‐D Display Using Luminance‐Modulated Two 2‐D Images Displayed at Different Depths

We have found a novel three‐dimensional (3‐D) display mechanism using only two 2‐D images displayed at different depths. It is based on a new perceptual phenomenon induced by the human binocular visual system and enables an observer using no extra equipment to perceive an apparent 3‐D image of continous depth when the luminance is divided between the 2‐D images according to the 3‐D image depth. We have also develop a prototype direct‐vision 3‐D display using this mechanism. It can easily produce moving 3‐D color images by using color conventional 2‐D displays.
