1. A method of driving an optical device comprising:
an optical device including
an optical member having an optical area on which light incidents, the optical area having a rectangular shape in a plan view,
a first actuator configured to displace the optical member around a first axis which passes through a center of the optical area in the plan view, and the first axis forms an angle smaller than 90° with a first side of the optical area, and
a second actuator configured to displace the optical member around a second axis which passes through the center of the optical area, and the second axis is 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.
