An anti-shake apparatus comprising a movable unit, a fixed unit, a first driving unit, a second driving unit, a third driving unit, a fourth driving unit, a first detector, a second detector, and a control unit is provided. The movable unit can be moved in a first and second direction. The movable unit can be rotated on a movable-plane. The fixed unit supports the movable unit. The first and second driving units supply driving forces in the first direction, to the movable unit. The third and fourth driving units supply driving forces in the second direction to the movable unit. The first detector detects a direction of a gravitational force acting on the movable unit. The second detector detects a rotational movement around a straight line perpendicular to the movable-plane. The 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.
