This paper examines visual effects of motion parallax (MP) which is an important element of depth perception. A display technology was developed which does not cause a delay of motion parallax to a viewer watching an image with a motion parallax related to viewpoint position. Using this apparatus, a method of control was examined which affects a viewer's emotion by changing the magnitude of the motion parallax. A term ‘gain of motion parallax Gm’ which represents the magnitude of a motion parallax is defined. An assumption is made that a visual effect induced by an image with a motion parallax depends on Gm. To prove this assumption, the undetectable threshold of a delay of a motion parallax was found to be approximately 60 ms. It was confirmed that the motion-parallax display apparatus developed has shorter delay than this value. By changing the value of Gm, subjective evaluations were carried out for three evaluation items: ‘sensation of depth,’ ‘reality’ and ‘linkage.’ The results show that these three items form functions of Gm which are ‘saturation shape,’ ‘dull peak shape’ and ‘sharp peak shape,’ respectively.
