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.
