摘要:
An indicating apparatus of a camera, has an indicating unit, a driving unit and an adjusting unit. The indicating unit includes an indicating member capable of indicating any of a plurality of indicated positions. The driving unit drives the indicating member on the basis of information on photography of the camera. The adjusting unit is capable of adjusting the indicated position of the indicating member irrespective of the information on the present photography of the camera. Each indicated position corresponds to an item of information on the photography of the camera.

This camera includes a viewfinder and a device (4) for detecting the visual line of a photographer looking through the viewfinder, an operation member (1), (8) such as a release button which is operated by the photographer to take a photograph, a means (2) for inputting calibration information, and a means for performing photography (5), (6), (7). The calibration information input means (2) operates in response to the operation of the operation member (1), (8), and inputs and stores calibration information when the photographer fixates on a target mark (3, b) visible within the viewfinder, based upon the visual line detected at that time by the visual line detection means (4). The object intended by the photographer to be photographed is detected and photographs it, based upon the visual line detected by the visual line detection means (4) and the stored calibration information.

A camera is capable of displacing a phototaking optical system in the direction of the optical axis by a drive source such as motor and setting the optical system to a plurality of positions. The camera includes a photo-taking optical system, photographing position setting means producing a command signal, a drive source, position detecting means outputting a position signal corresponding to the position of the photo-taking optical system, discriminating means for discriminating the direction of movement of the phototaking optical system, and control means for stopping the drive source and setting the photo-taking optical system at a position corresponding to the command signal as soon as the position indicated by the position signal coincides with the position indicated by the command signal when the discriminating means is discriminating a predetermined first direction of movement, stopping the drive source at a position beyond the position indicated by the command signal and then driving the drive source so that the photo-taking optical system is moved in the first direction when the disciminating means is discriminating a second direction of movement differing from the first direction of movement, and stopping the drive source and setting the photo-taking optical system at the position corresponding to the command signal as soon as the position indicated by the position signal coincides with the position indicated by the command signal.
摘要:
A camera containing a lens barrier therein is comprised of a helicoid rotatable about the optic axis, a rectilinear barrel threadably engaged with the inner side of the helicoid and having a holding portion for a lens barrier holding a photo-taking lens and protecting the photo-taking lens, a guide plate extending in the direction of the optic axis and engaged with the rectilinear barrel to rectilinearly guide the same through a cut-away groove, and a lens barrier held in the lens barrier holding portion and opened and closed in front of the photo-taking lens. The guide plate and the lens barriers are designed so as to be capable of overlapping each other in the direction of the optic axis, and the guide plate is designed so as not to hamper the opening-closing of the lens barriers even when they are in the overlapping position.
摘要:
Variable focus camera includes primary and secondary lens systems, in which only the primary lens system is used for wide angle shots while the combination of the primary with the secondary lens system is used for telephoto shots.The variable focus camera can exactly and positively control the focus change region, the automatic focusing region and other regions.
摘要:
A camera for use with interchangeable lens barrels that can be attached to and detached from the camera body has a drive mechanism that provides the generating source for the drive power of drive elements inside each lens barrel built into the camera body. The connecting structure that provides a connection between the camera body and lens barrels varies according to the type of lens barrel, for example, whether the lens barrel contains a fixed focal length lens or a variable focal length lens. So, the functions realized by the drive of the drive elements from the drive mechanism vary according to the type of lens barrel.

A camera having a cartridge compartment therein loaded with a film cartridge having a spool shaft projecting from an upper portion of the film cartridge. A switch is located in a space formed by an upper surface of the film cartridge, a side surface of the projecting portion of the spool shaft and an internal wall of the cartridge compartment. An operating member contacts the switch to operate the switch. The operating member partially projects from the camera back surface and is partially inserted into and operatively positioned in the space. The operating member is conveniently placed at a position on the camera surface for easy operation. Therefore, the switch is easily and conveniently operated and effective utilization of the internal space of the camera is employed to obtain a smaller size camera.
摘要:
A camera which switches between illuminating an external display and illuminating an internal display based on a specific photographic event, such as the pressing of the release button. The camera includes a first display, a first display illumination device which illuminates the first display, a second display, a second display illumination device which illuminates the second display, a control mechanism for controlling the first display illumination device and the second display illumination device so that the first display illumination device is not illuminating the first display when the second display illumination device is illuminating the second display and so that the second display illumination device is not illuminating the second display when the first display illumination device is illuminating the first display.
摘要:
A camera includes a photo-taking lens, an automatic focus adjusting device for effecting the automatic focus adjustment of the photo-taking lens, an eye-gaze detecting device for detecting the photographer's eye-gaze position in a finder field corresponding to a photographing picture plane, and producing an eye-gaze detection signal corresponding to the eye-gaze position, a focus adjustment signal producing device for outputting a plurality of focus adjustment signals corresponding to a plurality of detection areas in the photographing picture plane, and a control signal producing device for producing a control signal for controlling the automatic focus adjusting means, on the basis of the eye-gaze detection signal and the focus adjustment signals. The control signal producing device produces the control signal on the basis of the plurality of focus adjustment signals corresponding to the plurality of detection areas when the eye-gaze position indicated by the eye-gaze detection signal is at a position between the plurality of detection areas.
摘要:
An interchangeable lens camera including a lens barrel and a camera body. The lens barrel is attached to the camera body via a body side mount and a lens side mount. The lens barrel mounting mechanism, including the body side mount and the lens side mount, is capable of moving along the optical axis of the camera so as to move from a position where the lens barrel is completely collapsed within the camera body to a position where the lens barrel is fully extended for zoom photography. The shortest state of the camera is when the lens barrel is detached from the camera. The lens barrel includes a set tube that is movable along the optical axis, lens units for focusing light onto a film in the camera body, and lens protection elements that open or close depending upon the state of the lens barrel, i.e., detached or attached, collapsed or extended. The camera body includes a control circuit that controls the movement of the lens barrel based upon the state of several switches, some of which are located in the lens barrel.
