摘要：
본발명의일 실시예에따른액추에이터구동장치는렌즈캐리어에부착된감지자성체와대향하도록하우징에배치되는감지인덕터; 상기감지인덕터에기준신호를인가하고상기감지인덕터에흐르는인덕터전류를검출하는감지부; 상기인덕터전류에따라상기렌즈캐리어의위치를판단하는판단부; 및상기렌즈캐리어의위치및 위치제어신호에따라액추에이터를구동시키는구동부를포함할수 있다.
摘要（英）：
An actuator drive apparatus according to an embodiment of the present invention detects an inductor disposed in the housing so as to face with the sensed magnetic body attached to a lens carrier; Detecting unit for applying a reference signal to the sense inductor detects the inductor current flowing through the sense inductor; Determination unit for determining the position of the lens carrier according to the inductor current; And it may include a driving unit for driving the actuator according to the position and the position control signal of said lens carrier.
