Abstract: An attachment to a camera lens for creating a single slide transparency or photograph from two slide transparencies such that a before-and-after or combination picture can be formed on a single photograph or transparency comprising an enclosure formed from a plurality of opaque sides and one translucent side. An aperture is formed through one of the opaque sides and has a collar for connecting the slide duplicator to the camera lens. A slot located adjacent the single translucent side is used for engaging the slide transparencies that are to be photographed. Mirrors within the duplicator are arranged for reflecting and directing images formed from light rays passing through the translucent side and through the slides to the camera lens so that the camera can photograph the dual images onto a single transparency or photograph. First surface mirrors are used in lieu of regular mirrors for clearly and distinctly reflecting and directing the images.

Abstract: A multi-direction camera is provided in which a mirror (3) having a plurality of reflecting surfaces (31, 32) is disposed in front of a lens (4). The mirror (3) reflects the light from a plurality of directions and the lens (4) receives the reflected light to form an image on an image sensing device (7). In a first embodiment, a partitioning plate (81) is provided between the lens (4) and the edge line (33) of the mirror (3). The partitioning plate (81) optically isolates a plurality of reflecting surfaces (31, 32) to prevent a ghost image from appearing in the image taken. In a second embodiment, the mirror (3) is enclosed by an opaque cover (2), and the cover (2) has a transparent window (21, 22) opposing each of the plurality of reflecting surfaces (31, 32). The shields (23, 24), which are formed as a part of the window (21, 22), are arranged at locations away from the lens (4) such that an image of the shield is received by the lens (4).

Abstract: A panoramic camera has a camera housing rotatable about an axis of rotation that defines a viewpoint which points along a radial optical path that object rays traverse as the camera is rotated about its axis; a lens assembly having an optical path and a front nodal point mounted for rotation with the camera housing with the optical path of the lens offset from the radial optical path; a specular assembly including an object specular member along the radial optical path mounted for rotation with the housing that cooperates with the lens assembly for gathering object rays that traverse the radial optical path and for deviating them along the optical path of the lens assembly in such a way that the front nodal point of the lens subassembly virtually appears to lie on the axis of rotation thereby eliminating image smearing; and has an ambient light responsive controller including an ambient light sensor mounted for rotation with the camera housing for automatically varying the speed of rotation in direct relation

Abstract: In a lens-fitted photographic film unit, a connection lever makes one reciprocating movement when struck by a shutter actuating lever. The reciprocating movement of the connection lever is transmitted to a crank lever to a pair of shutter blades to cause the shutter blades to open and then close a shutter aperture. The connection lever is coupled to the crank lever through a connection pin and a cam slot. The cam slot has an actuating portion and a keeping portion. While the connection pin moves along the actuating portion, the movement of the connection lever is transmitted to the shutter blades through the crank lever to open and close the shutter aperture. While the connection pin moves along the keeping portion, the movement of the connection lever is not transmitted to the shutter blades so that the shutter blades are kept in the opened position.

Abstract: A multi-direction camera comprising a mirror 3 having a plurality of reflecting surfaces 31 and 32 disposed in front of a lens 4. The lens 4 receives light reflected from the mirror 3 from a plurality of directions and forms an image by the image sensor 7. The mirror 3 can be moved linearly by an actuator 8. The arrangement of the mirror 3 and lens 4 allows the camera to image road conditions of multiple directions at the same time. The camera can also image a road condition in a single direction with a wider scope manually or automatically when the road condition in that direction needs to be confirmed preponderantly.

Abstract: A camera includes a photographing optical system in which at least one of a plurality of reflecting surfaces is disposed between a plurality of lenses and the optical path is bent by two reflecting surfaces including the at least one reflecting surface so that an image of an object falls on a film surface substantially facing the object; and an observing optical system of real image type in which one of the two reflecting surfaces is configured as a movable or path splitting surface to conduct light outside the photographing optical system so that the image of the object can be observed. Thus, the height as well as the entire length of the camera is reduced and compact design of the camera can be attained.

Abstract: A telephotographic optical system is incorporated into a mechanism unit with an exposure mechanism, and the mechanism unit is removably attached to a main body having a cassette chamber and a film roll chamber as an integral body. The telephotographic optical system is constituted by a telephotographic taking lens, and a pair of mirrors attached to an exposure chamber so as to conduct light entering through the taking lens along a Z-shaped light path toward an exposure aperture. A lens aperture changing mechanism is also incorporated in the mechanism unit. A switching member of the lens aperture changing mechanism is disposed on an upper wall portion of the film unit. An aperture-stop member having at least a lens aperture is moved by the switching member so as to place the lens aperture in the exposure light path.

Abstract: A lens-fitted photo film unit includes a taking lens, a film containing section, and an exposure unit secured in front of the film containing section. An exposure aperture is formed in the film containing section, which also includes a supply chamber and a take-up chamber. The supply chamber contains unexposed photo film. The take-up chamber is adapted to winding the photo film after exposure. The supply chamber and the take-up chamber are disposed beside the exposure aperture opposite to one another. The exposure unit includes a shutter device. An exposure tunnel is formed through the exposure unit and around a light path from the taking lens toward the exposure aperture, and protects the light path from ambient light. The exposure tunnel extends to the rear of the unit so that any of a variety of different exposure units can be used, depending on the focal length of the taking lens.
