Abstract
We studied a new 3-D display that uses two stereoscopic displays instead of two 2-D displays in a depth-fused 3D display. We found that two 3-D images with the same shape displayed at different depths by the two stereoscopic displays were fused into one 3-D image when they were viewed as overlapping. Moreover, we found that the perceived depth of the fused 3-D image depends on both the luminance ratio of the two 3-D images and their original perceived depth. This paper presents the simulation results for the perceived depth of the fused 3-D image on the new 3-D display. We applied a model in which the human visual system uses a low-pass filter to perceive the fused image, the same as that used for a conventional DFD display. The simulation results revealed that the perceived depth of the fused image changed depending on both the luminance ratio of the two 3-D images and their original perceived depth, as in the subjective test results, and the low-pass filter model accurately presented the perception of a 3-D image on our 3-D display.
