A camera module includes an imaging lens assembly having an optical axis and a driving device including a fixed component, a lens carrier, a magnet carrier, a first ball group, and a second ball group. The imaging lens assembly is disposed in the lens carrier. The magnet carrier has a first groove group extending parallel to the optical axis and a second groove group extending perpendicular to the optical axis. One of the fixed component and the lens carrier has a third groove group disposed opposite to the second groove group. The imaging lens assembly is movable with respect to the fixed component on a plane perpendicular to the optical axis via the second ball group disposed between the second groove group and the third groove group and along a direction parallel to the optical axis through the first ball group disposed in the first groove group.

A controllable aperture stop includes a light pass portion, a fixed portion, a driving part and rollable elements. The light pass portion includes movable blades together surrounding a light pass aperture. The fixed portion has shaft structures corresponding to the movable blades. The driving part includes a rotatable element, a magnet and a coil. The rotatable element is for driving the movable blades to rotate relative to the shaft structures to adjust the size of the light pass aperture. The magnet is disposed on the rotatable element. The coil corresponds to the magnet. The magnet and the coil are to drive the rotatable element to rotate around the light pass aperture. The rollable elements are disposed between the fixed portion and the rotatable element and arranged around the light pass aperture, so the rotatable element is rotatable relative to the fixed portion.

An imaging lens with an optical axis includes a lens carrier and a variable through hole assembly. The lens carrier is configured for at least one lens element to be disposed therein, and the lens carrier includes a mount structure. The variable through hole assembly includes a plurality of movable blades and a rotatable element. The movable blades movably and together surround the optical axis to form a through hole, and a size of the through hole is variable by movement of the movable blades. The rotatable element is connected to the movable blades, and the rotatable element moves the movable blades to vary the size of the through hole. At least one of the movable blades and the rotatable element of the variable through hole assembly is disposed on the mount structure.

A light pass aperture module, in order along a central axis, includes a blade assembly and a cap. The blade assembly includes a plurality of blades. The blades form a light pass aperture, and the light pass aperture is variable in size with the central axis as a center. The cap covers the blade assembly. The cap has a through hole, and the through hole is disposed corresponding to the light pass aperture. The cap includes a surface level down structure. The surface level down structure is disposed corresponding to one of the blades, and the surface level down structure is closer to the one blade than the through hole.

A lens driving module is configured to provide an imaging lens system with auto-focus functionality. The imaging lens system is disposed between a preloading element and a driving base of the lens driving module. The preloading element includes an injection molded part and a ferromagnetic part partially embedded in the injection molded part. A rollable element is disposed in each of mounting structures of the injection molded part and in contact with a displaceable lens carrier of the imaging lens system. The ferromagnetic part and a magnet disposed on the displaceable lens carrier together generate a magnetic attraction force, such that the displaceable lens carrier exerts a preloading force on the rollable element. The driving base includes a driving coil and an electrical wiring pattern. The driving coil corresponds to the magnet for generating a driving force to drive the displaceable lens carrier to move along the optical axis.

A reflection module capable of image stabilization includes a reflecting element, a rotatable holder, a fixed base, a spherical supporting structure, an auxiliary supporting structure and an image stabilizing actuator. The reflecting element having a reflecting surface for folding optical path of incident light is disposed on the rotatable holder. The fixed base is connected to the rotatable holder via an elastic element. The spherical supporting structure is disposed between the rotatable holder and the fixed base. The auxiliary supporting structure disposed on at least one of the rotatable holder and the fixed base and corresponds to the spherical supporting structure. At least part of the image stabilizing actuator is disposed on the rotatable holder for driving the rotatable holder to rotate by taking the spherical supporting structure as rotation center. The spherical supporting structure is a ball having at least three contact points with the auxiliary supporting structure.
