  • Patent number: 9106833
    Abstract: A blur correction apparatus is provided that includes a blur correction mechanism, a locking member, a shift drive processor and an unlocking driver. The blur correction mechanism compensates for camera shake by driving a movable portion provided with one of a correction lens and an imaging device. The locking member restricts movement of the movable portion within a locked range of motion. The shift drive processor moves the movable portion a predetermined distance toward a center of the locked range of motion when locking by the locking member is released and the predetermined distance is shorter than the distance from the movable portion to the center. The unlocking driver moves the locking member to an unlocked position after moving the movable portion the predetermined distance away from the locking member.

  • Patent number: 8355052
    Abstract: A photographic apparatus comprises a movable platform and a controller. The movable platform has an imager that captures an optical image through a taking lens, and is movable and rotatable on an xy plane perpendicular to an optical axis of the taking lens. The controller calculates an inclination angle of the photographic apparatus, which is formed by rotation of the photographic apparatus around the optical axis, as measured with respect to a level plane perpendicular to the direction of gravitational force, and performs a controlled movement of the movable platform for an inclination correction based on the inclination angle. The controller calculates the inclination angle but stops the controlled movement when the photographic apparatus is set to a sleep mode.

  • Patent number: 8194142
    Abstract: A photographic apparatus comprises a movable platform and a controller. The movable platform has an imager that captures an optical image through a taking lens, and is movable and rotatable on an xy plane. The controller calculates an inclination angle of the photographic apparatus, and performs a controlled movement of the movable platform for an inclination correction by rotating the movable platform from an initial state on said xy plane in accordance to a rotation quantity of the movable platform. The controller performs the controlled movement to offset the inclination angle by the rotation quantity, when the photographic apparatus is in a first inclination state. The controller performs the controlled movement to maintain an inclined state where the movable platform is rotated from the initial state in accordance to either the first angle or the negative of the first angle, when the photographic apparatus is in a second inclination state.

  • Patent number: 8111293
    Abstract: A photographic apparatus comprises a movable platform and a controller. The movable platform has an imager and is movable and rotatable on an xy plane perpendicular. The controller calculates an inclination angle of the photographic apparatus, and performs a controlled movement of the movable platform for an inclination correction based on the inclination angle. The controller calculates a first position of the movable platform before the inclination correction. The controller calculates a second position of the movable platform after the inclination correction. The controller determines whether the movable platform should be moved to a third position before moving from the first position to the second position in the inclination correction, on the basis of a positional relationship between the first position and the second position. The third position is a position of the movable platform in an imaging operation by the imager without the inclination correction.

    Abstract: A dust removal apparatus of a photographing apparatus comprises a movable unit and a controller. The movable unit has an imaging device and is movable. The controller moves the movable unit on a plane that is parallel to a first direction and a second direction. The first direction is perpendicular to an optical axis of a photographing optical system that captures an optical image on a photographing surface of the imaging device. The second direction is perpendicular to the first direction and the optical axis. The controller moves the movable unit to a predetermined position that does not make contact with a boundary of a range of movement of the movable unit, and strikes the movable unit against the boundary of the range of movement in the second direction under the condition where a coordinate value in the first direction of the movable unit is held constant, as a dust removal operation.
