A method of driving an optical device is provided. The optical device including an optical member, a first actuator which displaces the optical member around a first axis, and a second actuator which displaces the optical member around a second axis perpendicular to the first axis. The method including exciting the first actuator by inputting a first drive signal to the first actuator, exciting the second actuator by inputting a second drive signal to the second actuator, and setting a value of the second drive signal to a value for substantially stopping exciting the second actuator in a period of the exciting the first actuator.
