摘要： A head-mounted display apparatus designed so that the utilization efficiency of display light from an image display device is increased and it is possible to control the brightness of an outside, real world image and also possible to shut off light from the outside. A liquid crystal display device (2) is disposed so that the direction of polarization of light emerging from the liquid crystal display device (2) is parallel to the plane of incidence on a polarization beam splitter (5) disposed in front of an observer's eye. The light emerging from the liquid crystal display device (2) is transmitted by the PBS (5) and reflected by a concave mirror (3) through a quarter-wave plate (6) disposed on the exit side of the PBS (5). The reflected light passes through the quarter-wave plate (6) and enters the PBS (5) again. Since the display light passes through the quarter-wave plate (6) twice during the round-trip travel, almost all the display light is reflected by the PBS (5) to enter the observer's eye. Accordingly, the light emerging from the liquid crystal display device (2) reaches the observer's eye with substantially no loss of light. With regard to light (4) from the outside world, a half of the incident light is reflected by the PBS (5), and the other half reaches the observer's eye.

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 camera of this invention incorporates a finder unit capable of changing its magnification corresponding to any one of plural zoom lens barrels (first, second lens barrels) each having different zoom range. When installing the finder unit, first, a positioning pin is inserted into a positioning hole in a rotary frame so as to hold the lens barrel in standard zoom condition. Then, a finder positioning pin is inserted into a cam gear positioning hole and main body positioning hole in finder cam shaft so as to hold a finder lens at a variable magnification position corresponding to the standard zoom condition. With that condition, a zoom driving gear arrangement is meshed with a driving gear portion and cam gear in a rotary frame so that the lens barrel and finder are assembled with each other. This camera realizes reduction of product development term and production cost.

摘要： The invention concerns an optical system adapted to split an optical path from a taking optical system into a finder optical system, which has a camera-shake correction function best suited for the finder optical system, and so on. This optical system comprises a taking optical system and a finder optical system. The taking optical system comprises an optical path splitter means operable to split an optical path into the finder optical system, and the finder optical system includes a relay optical system RLS for re-forming a subject image once. Anti-shake is implemented by shifting an optical subsystem RL that forms a part of the finder optical system in a plane vertical to an optical axis.
