1. An imaging camera driving module, comprising:
a lens unit, comprising:
an imaging lens assembly, having an optical axis;
a driving mechanism, wherein at least a part of the driving mechanism is coupled to the lens unit, and the driving mechanism is configured to drive the lens unit to move in a direction parallel to the optical axis;
a sensing mechanism, comprising:
a plurality of sensing magnets, fixed to the lens unit, wherein at least a part of the lens unit is located between the plurality of sensing magnets and the driving mechanism, and the plurality of sensing magnets are blocked by the at least a part of the lens unit from facing the driving mechanism; and
a plurality of sensing elements, disposed on an image side of the imaging lens assembly and on an image side of the plurality of sensing magnets, wherein each of the plurality of sensing elements is disposed corresponding to one of the plurality of sensing magnets, and each of the plurality of sensing elements is configured to detect a relative position of the sensing magnet corresponding thereto; and
an image surface, having a central axis, wherein the image surface is disposed on the image side of the imaging lens assembly, and the optical axis of the imaging lens assembly passes through the image surface;
wherein a minimum distance in parallel with the central axis from one of the plurality of sensing magnets to the sensing element corresponding thereto is Da, and the following condition is satisfied:
0 mm≤Da≤0.93 mm.
