ABSTRACT:
An anti-shake apparatus includes a movable unit supported by a fixed unit and movable in first and second directions as well as rotated on a movable plane. A first and second driving unit supply driving forces to the movable unit in a first direction. A third and fourth driving unit supply driving forces to the movable unit in a second direction. A first detector detects a direction of a gravitational force acting on the movable unit. A second detector detects a rotational movement around a straight line perpendicular to the movable plane. A control unit controls the third and fourth driving forces to correct the rotational movement when the gravitational direction is parallel to the first direction. The control unit controls the first and second driving forces to correct the rotational movement when the gravitational direction is parallel to the second direction.
