Claim 0:
1. An actuator control apparatus comprising:
an actuator which changes an optical path of a lens;
a lens support member; and
a controller which controls the actuator,
wherein the actuator includes a first driver and a second driver, which are disposed at a first side of the lens support member, and a third driver and a fourth driver which are disposed at a second side of the lens support member,
wherein 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,
wherein the controller applies a first current to the second driver and the third driver,
wherein the controller applies a second current to the first driver and the fourth driver, and
wherein the controller determines a difference between an absolute value of the first current and an absolute value of the second current or magnitude of an absolute values of the first current and the second current to be applied to the drivers using at least one of the first distance, the second distance, and a tilting direction of the lens.
