Abstract: According to an embodiment of the present invention, in a camera device including first and second cameras, focal position information of the first camera and focal position information of the second camera are matched with each other. Also, the accuracy of the current focal position of the first camera is determined based on the phase difference of images obtained by the first camera when the first camera is auto-focused. Subsequently, when the accuracy of the current focal position of the first camera is low, an accurate focal position of the first camera is tracked by using the matched focal position information of the second camera. As described above, according to the present embodiment, when an auto-focusing function of the first camera is activated, focal position movements are tracked by using the focal position information of the second camera as well as zoom tracking of the first camera, and thus, the accuracy can be improved.

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.
