New depth-fused 3-D perception on 3-D display system using two stereoscopic displays

We describe a new type of depth-fused 3-D (DFD) perception that occurs when watching a display system that uses two stereoscopic displays instead of two 2-D displays in a conventional DFD display Subjective tests for this display revealed that two 3-D images of the same shape displayed by the two stereoscopic displays were fused into one 3-D image when they were viewed as overlapping as in a conventional DFD display in which two 2-D Images are fused. The perceived depth of the fused 3-D image depends on both the luminance ratio of the two 3-D images and their depth specified by binocular disparity. This result demonstrates that DFD perception is dominated by the effects of binocular disparity and image intensity, i.e., the effect of the depth of focus is much weaker. (c) 2007 SPIE and IS&T.
