Abstract:
A driving controller provides a first driving signal having a first driving frequency to a first actuator that causes a mirror portion to swing around a first axis, provides a second driving signal having a second driving frequency to a second actuator that causes the mirror portion to swing around a second axis intersecting with the first axis, and derives a first driving condition of the first actuator under which the first driving frequency is less than a first resonance frequency around the first axis.
