Abstract
An imaging camera driving module includes a lens unit, a driving mechanism, a sensing mechanism and an image surface. At least a part of the driving mechanism is coupled to the lens unit to drive the lens unit to move in a direction parallel to the optical axis. The sensing mechanism includes sensing magnets fixed to the lens unit and sensing elements not facing the driving mechanism. The sensing elements are disposed on an image side of the imaging lens assembly of the lens unit and corresponding to the sensing magnets. The sensing elements are configured to detect a relative position of the sensing magnets. The image surface is disposed on the image side of the imaging lens assembly, and the optical axis passes through the image surface. The sensing mechanism is configured to detect a tilt of the optical axis with respect to the central axis.
