    Abstract: An anti-shake apparatus comprises a movable-unit, a fixed-unit, a signal-processor, and a controller. The movable-unit has an imaging-device and is movable in first- and second-directions, supported by the fixed-unit. The fixed-unit has a horizontal-hall-element for detecting a first-location, and a vertical-hall-element for detecting a second-location. The signal-processor outputs a first-signal specifying the first-location, from output signals of the horizontal-hall-element, to a first A/D-converter of the controller, and outputs a second-signal specifying the second-location, from output signals of the vertical-hall-element, to a second A/D-converter of the controller. The controller calculates the first-location in an A/D-converting-operation for the first-signal, and the second-location in an A/D-converting-operation for the second-signal.

  • Publication number: 20050041143
    Abstract: A three-dimensional image capturing device comprises a plurality of laser devices, and an imaging device, such as a CCD, having a plurality of photo-diodes. Each of the laser devices radiates a pulse modulated laser beam so as to detect distance information or data relating to a topography of a measurement subject. The laser beam is radiated onto the measurement subject and a reflected light beam is sensed by the CCD. Signal charge corresponding to a distance from the image capturing device to the measurement subject is accumulated in each of the photo-diodes, and thus the above distance information is sensed. Each laser beam, respectively radiated from each of the laser devices, shares illuminating area at the distance of the measurement subject, so that radiant energy of each laser beam can be reduced by sharing a single distance measurement operation among the plurality of laser devices.
