Abstract
In described examples, a transducer vibrates a lens element at a first frequency and a different second frequency. Controller circuitry selects one of a cleaning mode and a heating mode in response to an estimated temperature of the lens element. The controller circuitry activates the transducer to vibrate the lens element at the first frequency in response to the controller circuitry selecting the cleaning mode. The controller circuitry activates the transducer to vibrate the lens element at the second frequency in response to the controller circuitry selecting the heating mode.
