Abstract
A processor applies a first driving signal having a first driving frequency to a first actuator, applies a second driving signal having a second driving frequency to a second actuator, generates a first angle detection signal by performing first frequency filter processing based on the first driving frequency on an output signal of a first angle detection sensor, generates a second angle detection signal by performing second frequency filter processing based on the second driving frequency on an output signal of a second angle detection sensor, derives a first angle, which is an angle of a mirror portion around a first axis, based on the first angle detection signal, derives a second angle, which is an angle of the mirror portion around a second axis, based on the second angle detection signal, adjusts the first driving signal based on the first angle, and adjusts the second driving signal based on the second angle.
