    摘要: A head-mounted see-through display which enables an outside image and an electronic image to be selectively observed by making a liquid crystal shutter transparent or opaque. To eliminate the problem that during the observation of the electronic image the outside image is undesirably seen through the peripheral region of the electronic image, display light from a two-dimensional display device (11) is first transmitted by a half-mirror (12), and the transmitted light is reflected by a concave mirror (13). Then, the reflected light is reflected by the half-mirror (12) so as to be led to the observer's eye as an enlarged image. To prevent the outside light from entering the eye through the half-mirror (12) during the observation of the electronic image, a negative or positive type TN or STN liquid crystal shutter (10) is disposed in front of the half-mirror (12). When the electronic image is to be viewed, the shutter (10) is made opaque, whereas, when the outside image is to be viewed, the shutter (10) is made transparent.

    摘要: A visual image system is constructed as including: a three-dimensional visual image reproducer for transmitting a three-dimensional video signal; a parallax quantity detecting section for detecting a parallax quantity in the three-dimensional video signal from the three-dimensional visual image reproducer; a fatigue measure estimating section for estimating the degree of fatigue based on the detected parallax quantity and outputting an image switching signal correspondingly to a fatigue measure estimating quantity; a 3D/2D image switching section for providing an output by switching between three-dimensional and two-dimensional images based on the image switching signal; and an image display section for displaying a three-dimensional image or a two-dimensional image. The visual image system thereby fulfills the capability of suitably controlling the degree of three-dimensionality of stereoscopic images by inferring from the inputted video signal the degree of effects likely to be produced on the observer.

    摘要: A storage unit stores three-dimensional shape data of a plurality of objects, initial position data of the plurality of objects in a three-dimensional coordinate system, motion data of the plurality of objects in the three-dimensional coordinate system, and position data of first and second viewpoints in the three-dimensional coordinate system. First and second rendering units generate first and second two-dimensional image data obtained by rendering the plurality of objects in the three-dimensional coordinate system from the first and second viewpoints, respectively.

    摘要: An optical apparatus, e.g. a head-mounted display apparatus, which enables observation of a favorable image by eliminating flare and ghost images caused by unwanted light coming in through the gap between an observer's eyeball and an optical unit of the apparatus. Display light of an electronic image emanating from a liquid crystal display device and outside world light coming in through a liquid crystal shutter (7) are p-polarized light and therefore pass through a polarizing plate (8) and reach an observer's eyeball (1) without any loss. Meanwhile, light that undesirably comes in through the gap between the observer's face and the optical unit is generally natural light and hence unpolarized. Therefore, when the unwanted light passes through the polarizing plate (8) after being reflected from the eyeball (1) or a mirror (3), the light intensity reduces to 1/2. Although the light is successively reflected by the concave mirror (3) and the half-mirror (2) to reach the eyeball (1), the intensity ratio of the ghost image to the normal electronic image becomes 1/2. Thus, an electronic image of improved contrast can be observed.
