Perceived Depth Change of Depth-Fused 3-D Display with Changing Distance between Front and Rear Planes

We estimated the dependence of the perceived depth on luminance ratio by increasing the distance between the front and rear planes of a depth-fused 3-D (DFD) display. When the distance is great, the perceived depth has the tendency of nonlinear dependence on luminance ratio, which is very different from the almost linear dependence in a shortdistance conventional DFD display. In a long-distance DFD display, the perceived depth is split to near the front plane at 0–40% of the rear luminance, near the rear plane at 70–100%, and the midpoint of the front and rear planes at 40–60%. Thus, the luminance-ratio dependence of perceived depth changes widely with the distance. key words: 3-D display, 3-D visual illusion, luminance ratio, depth-fused3D
