Subjective image position in stereoscopic TV systems: considerations on comfortable stereoscopic images
Tetsuo Mitsuhashi · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1994
In stereoscopic picture systems, the image should be reproduced in a psychologically proper position that allows comfortable stereoscopic perception. Position matching in observer space between the stereoscopic image and a small marker was successfully adopted to measure the subjective image position. The subjective image position was measured for geometric figures and actual scenes while varying the resolution, contrast, brightness, and color between the L- and R-pictures. The image moves closer to the screen in proportion to the increase in resolution difference. A pair of color and darker monochrome pictures can reproduce acceptable stereoscopic images without conspicuous color rivalry. Mental fatigue is also an important factor in comfortable stereoscopic image viewing. The CFF is discussed together with other factors such as accommodation characteristics, picture quality, and viewing conditions that relate to future stereoscopic TV systems that allow comfortable viewing.
