    Abstract: There are provided an optical deflector driving system and the like that can prevent occurrence of abnormal oscillation in an optical deflector even in a case where change in offset (or amplitude) is reflected. An optical deflector driving method includes: a change instruction input step (S20) of inputting an instruction to change at least one of a first driving signal corresponding to a first driving voltage and a second driving signal corresponding to a second driving voltage, the first driving voltage and the second driving voltage being applied to an actuator swinging a mirror portion of an optical deflector around a swing axis; a determination step (S21 and S23) of determining, in a case where the instruction is input, a timing when a voltage of a driving signal to be changed out of the first driving signal and the second driving signal becomes minimum; and a change reflection step (S25 and S27) of reflecting, in a case where it is determined that the timing when the voltage of the driving signal to be changed becomes minimum comes, the change on the driving signal to be changed.
