摘要:
A camera having multiple display functions and/or a date imprinting function wherein the display can alternately switch between displaying the date and the film frame number. The frame number is displayed when winding blank film and the date is displayed at other times. The display also has an indicator which lights up or flashes to indicate the status of the camera power source. The display also shows the date and this date can be imprinted on film when a photograph is taken. The date can be imprinted whether or not the camera is in a date correction mode when the photograph is taken. A multiple function button is used to change photographic information shown on the display, wherein different functions correspond to different camera modes. Adequate safeguards are therefore provided by this camera to prevent accidental changing of information.

An image deflection preventing device for a camera, such as a still camera which is used to drive a deflection preventing optical system in accordance with readings from angular velocity sensors and other circuitry. Moreover, an exposure mode selection device is included to select strobe photography according to the focusing distance from a distance measuring unit maintained in the camera to a subject to be photographed. The selection device can select strobe photography when the focusing distance is closer than a predetermined distance or when photographic magnification from a focal length detection unit to a subject to be photographed is greater than a predetermined value. The selection of strobe photography is done using results from a photometric unit in conjunction with the determination of a brightness level. In particular, if a given brightness level is equal to or greater than a predetermined value, strobe photography is selected, otherwise, exterior light photography is selected. The brightness level for selection of strobe photography is typically higher at closer distances, longer focal lengths, or larger photographic magnifications.

A film scroll detection mechanism for a camera does not require a large encoder for use in controlling the scrolling of the film, while still producing a large number of pulse signals, thereby allowing a camera to be made smaller. A connection mechanism links a film scroll detection roller and a pulse signal generator. The connection mechanism causes an encoder of the pulse signal generator to rotate through a larger angle in comparison to the rotation of the aforementioned film scroll detection roller. This allows the encoder to be made with a smaller radius than previous devices. Additionally, the connection mechanism permits the axis of rotation of the encoder to be offset from the axis of rotation of the film scroll detection roller, which allows for a further reduction in the size of the camera.

A vibration compensation mode selection apparatus and associated visual display for a camera which allows a photographer to enable or disable a vibration compensation unit while receiving visual feedback regarding the operation state of the vibration compensation unit and information regarding the vibrations detected within the camera. A vibration detection unit is provided to output a signal indicating the amount and direction of vibrations experienced by the camera. A vibration compensation unit drives the vibration compensation lens perpendicular to the optical axis of a photographic lens system to correct for the vibrations detected by the vibration detection unit. A button is provided on the front face of the camera to enable the photographer to disable the vibration compensation unit by pressing the button. A display unit is provided to indicate to the photographer whether the vibration compensation system has been enabled or disabled. For example, the display unit can be configured to flash at a high frequency when the vibration compensation unit has been disabled. Further, the display unit can be configured to provide information regarding the severity of the vibrations detected within the camera. Specifically, the display unit can be configured to steadily illuminate to indicate vibrations which can be corrected by the vibration compensation system, and at a slow rate to indicate vibrations which are outside the correctable range of the vibration compensation unit. The display unit can either be provided within the viewfinder or on the body of the camera in a location easily visible by the photographer.
摘要:
A camera with a data imprinting device has a plurality of in-line LEDs producing light focused by an optical system upon a photographic film at a first and a second position, corresponding to a full size format and a panorama size format, respectively. The focused light imprints data images upon the film at the first position are larger than data images imprinted at the second position. The optical system has first and second prisms, with integrated lenses, for reflecting and focusing the light upon the film at the first and second positions, respectively. A shutter plate is selectively positioned over apertures through which the light is focused, thus blocking the light and allowing only a selected imprint to be made upon the film. A vertical pattern of the data image is created by a controller selectively illuminating the in-line LEDs while a horizontal pattern is produced by the controller illuminating the LEDs in coordination with the movement of the film past the apertures. The controller actuates a motor for advancing the film and has a sensor for detecting film travel. A first embodiment has the first prism positioned further from the film than the second prism, which is positioned further from the LEDs than the first prism, such that reflected light from the first prism has a path intersecting that of incident light of the second prism. A second embodiment has the prisms offset from each other in the plane of the film such that light paths do not intersect. The first embodiment has a narrower width than the second embodiment while the second embodiment has a shallower depth than the first embodiment.

A data imprinting device for a camera has a light source, a diaphragm member, and an optical member mounted on support structures integrally formed in a body of the camera. Another embodiment of the invention includes first and second optical members for imprinting data at two respective locations, upon a film, corresponding to full size and panorama size modes of operation. A shutter slides to obstruct emergent light from one of the first and second optical member thus disabling it from imprinting. The first and second optical members are integrally formed in a bracket structure which is mounted in a body of the camera. Embodiments includes the first and second optical members having emergent planes equidistant from the film. The first and second optical elements have incident planes either offset in a direction parallel with the film or perpendicular to it. Similar exposure characteristic at the two respective locations are maintained by controlling numerical apertures and transmittances of the first and second optical members.
摘要:
A vibration correction system for a camera using a correcting lens driven by a reduction gear train attached to a motor. Image deflection, originating from vibration and the like of the camera, is prevented by shifting the correcting lens. A movement detector, to detect the amount of movement of the correcting lens, is arranged near the drive shaft of the motor or near the first couple of gears of the reduction gear train. After the correcting lens has been driven, the connecting lens is reset to a predetermined standard position, based on the output of the movement detector. By placing the movement detector on or near the drive shaft, a high resolving power is obtained. Accordingly, the correcting lens can be shifted with fine precise movements, and accurate correction of image deflection becomes possible.
