Abstract: An imaging lens driving module includes a lens carrier, a molded receiving base, a rolling element, a molded frame element and a driving mechanism. The lens carrier defines an optical axis. The molded receiving base is configured to receive the lens carrier. The rolling element is disposed between the lens carrier and the molded receiving base, and the lens carrier is allowed to be displaceable along the optical axis and relatively to the molded receiving base. The molded frame element is coupled with the molded receiving base for defining an inner space to receive the lens carrier. The driving mechanism drives the lens carrier displaceable along the optical axis, and includes a driving magnet and a driving coil, wherein the driving magnet is disposed on the lens carrier, the driving coil is corresponding to and faces towards the driving magnet.

Abstract: A camera module includes a fixed base, a carrier, an elastic element, an imaging lens, a coil, a magnetic element, a connection wire and a light-blocking coating. The carrier is disposed opposite to the fixed base and has a bobbin. The elastic element is connected to the fixed base and the carrier so as to provide freedom of movement of the carrier with respect to the fixed base. The imaging lens is disposed on the carrier and has an optical axis. The coil is disposed on the carrier. The magnetic element is disposed corresponding to the coil so as to provide a driving force for moving the carrier. The connection wire is disposed on the bobbin and electrically connected to the elastic element and the coil, and the connection wire has at least part facing towards the optical axis where the light-blocking coating is disposed.

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.
