Abstract:
According to an embodiment of the present invention, an actuator control apparatus comprises: an actuator changing an optical path of a lens; and a controller controlling the actuator, wherein the actuator comprises a first driver and a second driver which are arranged on a first side of a lens support member, and a third driver and a fourth driver which are arranged on a second side of the lens support member. A first distance between the first driver and the second driver is different from a second distance between the first driver and the third driver, and the first driver and the fourth driver are located in a diagonal direction with respect to each other. The controller applies a first current to the second driver and the third driver and applies a second current to the first driver and the fourth driver. When the lens is moved in a diagonal direction, an absolute value of the first current is different from an absolute value of the second current.
