摘要:
An actuator and a camera module including the same are provided. The actuator driving apparatus includes a detector configured to apply a reference signal to a driving coil of an actuator and detect a coil current flowing in the driving coil, a calculator configured to determine a position of a lens carrier based on the coil current, and a driver configured to drive the actuator based on the position of the lens carrier and a position control signal.
