Abstract:
1. A camera driving apparatus, comprising: a camera section including an imaging element having an imaging plane, a lens having an optical axis and provided for forming an image of a subject on the imaging plane, and a lens barrel for holding the lens; a movable unit having at least one attracting magnet positioned adjacent a lower surface of the moveable unit, the moveable unit encompassing the camera section built therein, and the movable unit having a first convex partial spherical surface along an outer surface thereof; a fixed unit having at least one magnetic member and having a recess loosely fitted with at least a part of the movable unit, wherein a magnetic attracting force between the at least one attracting magnet and the at least one magnetic member puts the first convex partial spherical surface of the movable unit and the recess into point or line contact with each other, and thus the movable unit is freely rotatable around a sphere center of the first convex partial spherical surface as the center of rotation; a panning driving section for inclining the camera section in a panning direction with respect to the fixed unit; a tilting driving section for inclining the camera section in a tilting direction, perpendicular to the panning direction, with respect to the fixed unit; a rolling driving section for rotating the camera section in a rolling direction around the optical axis of the lens, with respect to the fixed unit; a first detector for detecting a tilt angle of the camera section in the panning and tilting directions with respect to the fixed unit; and a second detector for detecting a rotation angle of the camera section in the rolling direction; wherein the second detector is provided adjacent to the sphere center of the first convex partial spherical surface.
