Claim 16:
17. A cleaning device comprising:
a translucent body in a field of view of an imaging device;
a vibrator to vibrate the translucent body;
a driver to drive the vibrator;
a determiner to determine whether foreign matter is adhered to a surface of the translucent body; and
a controller to control the driver, wherein
when the determiner determines that the foreign matter is adhered to the surface of the translucent body, the controller is configured or programmed to control the driver such that vibration of the translucent body has a vibration acceleration of about 1.5×105 m/s2,
when the determiner determines that the foreign matter is adhered to the surface of the translucent body when the controller controls the driver such that vibration of the translucent body has a prescribed vibration acceleration, the controller is configured or programmed to control the driver such that vibration of the translucent body has a higher-order resonant frequency, and
after the translucent body is vibrated at the higher-order resonant frequency, the controller is configured or programmed to control the driver such that vibration of the translucent body has a resonant frequency.
