  • Patent number: 6272288
    Abstract: 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.

  • Patent number: 6044231
    Abstract: A camera has a data imprinting device having an optical system focussing light from an LED array on a photographic film at first and second positions corresponding to full-size and panorama-size picture formats. In a first embodiment the optical system has two lens elements, at differing distances from the LED array, each aligned to imprint data at one of the two positions. In a second embodiment the optical system has a single lens element which moves from a first lens position to a second lens position at differing distances from the LED array. Amounts of light emitted by the LED array are modulated by a control system to produce correctly exposed imprinted data at both position. The control system compensates for differing numerical apertures of associated with the first and second positions. The control system also compensates for film speed. One embodiment of the invention modulates the amount of emitted light by adjusting a current level driving the LED array.

  • Patent number: 6002888
    Abstract: 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.

  • Patent number: 5999747
    Abstract: 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.

  • Patent number: 5950034
    Abstract: A camera having a retractable lens barrel which can be fully received in the camera body when the camera is not in use, such that the portion of the lens barrel closest to the back of the camera, i.e., nearest the image plane, stops forward of the portion of the electric supply battery extending furthest from the side wall of the camera body to which the electric supply battery is adjacent. As a result, the height of the camera can be made smaller. Moreover, a mounting board, with a release switch formed thereon and activated by a release button operated by a user, is located above a motor which drives the lens barrel, such that the load on the mounting board, during the activation of the release switch by pressure of the release button, is supported by the motor, so that it is not necessary to dispose a separate support member in the camera body, and the size of the camera can be made smaller.

  • Patent number: 5930042
    Abstract: An optical lens barrel having a lens group which serves as a vibration compensation lens group and a focusing lens group. The lens group is held by a holder movably secured to a plate. The lens group is movable within the plate on a plane perpendicular to an optical axis of the lens group via a pair of DC motors and associated gear trains. The DC motors and associated gear trains are mounted on the plate. The plate is slidably movable parallel to the optical axis of the lens group by a stepping motor via a series of concentric drive rings disposed around the plate. The drive rings also actuate an aperture mechanism which serves as a shutter. This reduces both the number of lenses and components needed to provide vibration compensation and autofocusing functions.

  • Patent number: 5715482
    Abstract: A miniaturized collapsible zoom camera changes viewfinder magnification in accordance with a change in the photographic magnification. The camera is equipped with a collapsible cam tube to cause a first lens group, which rotates around the optical axis, to move from a collapsed position to a position just before a minimum magnification position. Likewise, a zoom cam tube causes the first lens group, which rotates around the optical axis, to move from the minimum magnification position to a maximum magnification position. Sector gears are formed on the outer circumference of the collapsible cam tube and the zoom cam tube. Furthermore, the camera is equipped with a cam tube drive gear which cooperates with the sector gears. A drive motor causes the drive gear to rotate. Another gear cooperates only with the sector gear of the zoom cam tube while a variable power and movement mechanism causes variable power operation in the viewfinder.

  • Patent number: 5708266
    Abstract: An apparatus to detect the amount and direction of rotary motion for use in a vibration compensation system in an optical camera. An indicator disk is provided around the output shaft of a motor which actuates a compensation lens to compensate for vibrations to the camera. The periphery of the indicator disk is provided with a series of holes. A pair of photodetectors, are arranged on the periphery of the disk so as to detect the holes passing thereunder. The two photodetectors are separated by a distance equal to 3/4 of the distance between two holes. By comparing the pattern of signals emitted by the photodetectors the direction of rotation of the indicator disk can be determined. Further, the pulses in the output of either photodetector can be counted to determine the amount of movement. The actual direction and amount of movement as calculated is provided to a vibration compensation circuit as feedback for use in controlling the compensation lens.

  • Patent number: RE38541
    Abstract: A camera with a data imprinting device includes a generally triangular space adjacent a film spool. A roller, used to conform the film to the film spool is urged into the triangular space when the film diameter on the roller approaches a maximum diameter. A portion of an optical system for the data imprinting device is also located in the triangular space. The periods of film drive pulses are averaged to establish periods of data imprinting pulses. A plurality of the data imprinting pulses are generated for each film drive pulse. In a full size mode of operation, a first set of the data imprinting pulses are used to record imprinting data. In a panorama mode of operation, a second set of the data imprinting pulses are used to record the imprinting data. The second set of data imprinting pulses contains more data imprinting pulses than the first set of data imprinting pulses, whereby the data imprinted in panorama mode occupies a shorter length of the film than does the data imprinted in full size mode.
