Abstract: A driving mechanism is provided. The driving mechanism includes a movable portion, a fixed portion, a driving assembly, and an aperture module. The movable portion is used for holding an optical module. The optical module includes a substrate and an optical sensor, the optical module connects to an external circuit through the substrate, and the optical sensor is used for receiving a light. The movable portion is movable relative to the fixed portion. The driving assembly is used for driving the movable portion to move relative to the fixed portion. The aperture module is used for controlling size of an aperture, and the light enters to the optical sensor through the aperture.

Abstract: A control method of a driving mechanism is provided, including: the driving mechanism provides a first electrical signal from a control assembly to the driving mechanism to move the movable portion into an initial position relative to the fixed portion, wherein the control assembly includes a control unit and a position sensing unit; the status signal of an inertia sensing unit is read; the control unit sends the status signal to the control unit to calculate a target position; the control unit provides a second electrical signal to the driving assembly according to the target position for driving the driving assembly; a position signal is sent from the position sensing unit to the control unit; the control unit provides a third electric signal to the driving assembly to drive the driving assembly according the position signal.
