摘要： An image observation device which is so arranged that a user can look an image in through an ocular window thereof with the device being fitted to the user's head for example, that the image changes in linkage with movement of the user's head, and that unnecessary change of the image is prevented during the observation. The image observation device includes an eye access detector for detecting whether the user's eyes approach thereto or not, and includes, a controller by the operation of which the image changes in linkage with movement of the user's head only if the eye access detector detects that the user's eyes approach thereto, and by the operation of which the image does not change in linkage with movement of the user's head if the eye access detector does not detect that the user's eyes approach thereto.

摘要： The object is to provide an image viewing system that allows easy image viewing with reduced eyestrain, whether for wide-angle or enlarged viewing. The rotation of the viewer's head is detected by means of piezo-electric vibration gyroscopes 405 and 406, and the coefficient for setting the amount of change in the camera system's image shooting direction with reference to the detected direction is changed in accordance with the focal length of the camera system's zoom lens systems. Moreover, the amount of change in the image shooting direction may be changed manually by means of sensitivity setting lever 213 mounted on HMD 2.

摘要： An image display apparatus is provided with a screen having retro-reflectivity, a liquid crystal display device displaying an image, a projection optical system projecting the light of the liquid crystal display device onto the screen, and a beam magnifier located close to the screen and magnifying the light beams, included in the projected light, expressing individual points of the image. The beam magnifier is composed of a diffraction optical element or a diffusing plate, and magnifies each light beam so that the magnification is larger in the direction of the horizontal field of view than in the direction of the vertical field of view. When images having parallax are provided for the left and right eyes, an upper limit of the magnification of the light beams is set in consideration of the distance between the left and right eyes to prevent cross-talk.

摘要： A screen image observing device and method provides the sensations of virtual reality to the observer and reduces, to the extent possible, the discrepancy that is perceived by the observer between the movement of the observer's head and the displayed screen image. The device has a head tracking means, which detects the movement of the observer's head, and a screen image generating means, which generates image data based upon the result of the detection performed by the head tracking means. Image data is supplied to a display means.

摘要： A resonant optical device has a rod-like resonator made of a fiber-reinforced resin for resonant vibration. A reflecting mirror is supported on the leading edge of the resonator. A drive unit oscillates the resonator in a circumferential direction. The base edge of the resonator is anchored to a stationary platform. The reflecting mirror is oscillated by a torsional oscillation produced by oscillation from the drive unit so as to scan light incident on the reflecting mirror. The resonator satisfies the expression G/.rho..gtoreq.12.times.10.sup.6 Pa.multidot.kg.sup.-1 .multidot.m.sup.3, where the horizontal elastic modulus of the resonator is designated G, and the density is designated .rho.. The resonator also satisfies the expression .tau./G.gtoreq.0.01, where the torsional stress tolerance is designated .tau.. In one embodiment, the fiber-reinforced resin is a carbon fiber-reinforced resin.

摘要： An image display apparatus has a display section for displaying an image, an eyepiece optical system, and a transparent plate-shaped member for holding the eyepiece optical system. The image display apparatus is used with the eyepiece optical system placed in front of a viewer's eyes and with the plate-shaped member facing the eyes. The image display apparatus directs light from the display section through the eyepiece optical system to the eyes so that the viewer is presented with a virtual image of the image displayed on the display section and simultaneously permits light from the outside world to be transmitted through the plate-shaped member so as to be directed to the eyes so that the viewer is presented with an image of the outside world. The boundary surface between the eyepiece optical system and the plate-shaped member is so arranged as not to reflect light from the outside world incident thereon at angles of incidence greater than the Brewster angle toward the eyes.
