International ClassH04N 5/228AbstractAn optical device with an imaging device for forming an image of a subject with a lens device includes a lens unit, a movable member making the lens unit movable within a plane orthogonal to the optical axis of the lens unit, an image pickup device imaging the subject image formed by the lens device, a fixed member limiting the movement of the movable member in the optical axis direction, at least three balls rolling between the movable and fixed member, a vibration detecting unit, and pitch and yaw direction drive units for driving the movable member in the pitch and yaw directions within the optical axis orthogonal plane, respectively. The pitch and yaw direction drive units press the movable member toward the fixed member side by means of magnetic pressing forces caused by magnetic attractive action between drive magnets and yokes.Field of SearchCamera image stabilizationElectrical motion detection Variable angle prisms Differentiating unintentional from purposeful camera movement (pan, tilt) Motion correction Including both electrical and mechanical correcting devices Electrical (memory shifting, electronic zoom, etc.) Mechanical Optics, lens shifting CAMERA SHAKE SENSING With accelerometer With photoarray Having stabilization system | |
