Claim 19:
20. A photographing module comprising:
a lens assembly comprising at least one lens element;
a reflection element located on an object side of the lens assembly, wherein the reflection element has a reflection surface, and the reflection surface is configured to redirect an incident light traveling along an incident optical axis towards the lens assembly;
an image sensor disposed on an image surface of the lens assembly, wherein the image sensor is configured to receive light coming from the lens assembly;
a lens element driving module comprising an axial voice coil motor, wherein the lens element driving module drives the lens assembly to move along a lens optical axis of the lens assembly by the axial voice coil motor, the axial voice coil motor comprises an axial motor coil and an axial motor magnet, each of the axial motor coil and the axial motor magnet has an axial motor corresponsive surface, and the two axial motor corresponsive surfaces face each other; and
an image sensor driving module comprising:
a fixed member;
a movable plate, wherein the image sensor is disposed on the movable plate, the movable plate has a degree of freedom and is movable relative to the fixed member, the degree of freedom is defined by a first dynamic axis, and the first dynamic axis is orthogonal to the lens optical axis;
a plurality of rollable elements located between and in physical contact with the fixed member and the movable plate; and
a lateral voice coil motor configured to drive the movable plate to move so that the image sensor can be moved in directions based on the first dynamic axis, wherein the lateral voice coil motor comprises a lateral motor coil and a lateral motor magnet, each of the lateral motor coil and the lateral motor magnet has a lateral motor corresponsive surface, and the two lateral motor corresponsive surfaces face each other;

wherein the axial motor corresponsive surfaces and the lateral motor corresponsive surfaces are parallel to the incident optical axis.
