Abstract: A camera module includes a base, a lens module, a reflection module, a longitudinal guiding bar, a transverse guiding bar and a shaft guiding bar. The lens module has an optical axis and is disposed on the base. The reflection module includes a reflective element disposed on the base and located on an object side of the lens module. The longitudinal and transverse guiding bars are disposed between the base and the lens module and respectively extend in a first direction parallel to the optical axis and a second direction perpendicular to the optical axis. The shaft guiding bar is disposed between the base and the reflection module and extends in the second direction. The lens module is movable along the longitudinal and transverse guiding bars, respectively, and the reflective element is rotatable by taking the shaft guiding bar as a rotation axis.

Abstract: Provided is a lens assembly driving module including a photographing lens assembly, a first driving mechanism and a second driving mechanism. The photographing lens assembly includes N lens elements and has an optical axis passing through the N lens elements. The first driving mechanism drives at least N/2 said lens elements to move along the optical axis of the photographing lens assembly. The second driving mechanism enables a relative distance along the optical axis of two adjacent ones of the N lens elements to vary. Therefore, any specific one of the lens elements is capable of being driven to optimize optical imaging resolution of various fields of view independently within a real shot at different object distances.
