    Abstract: A method for removing foreign substances from a camera system is provided. The camera system includes a camera device with a transparent cover having a piezoelectric component. First, a type of the foreign substances is identified based on temperature, an image captured by the camera system, and a voltage change of the piezoelectric component. A sequence of frequencies is applied to the piezoelectric component and a resonant frequency is acquired. Thereafter, the foreign substances are removed from the camera system. A vibration frequency and a vibration time period for the piezoelectric component are determined according to the identified type of the foreign substances. The vibration frequency is based on the resonant frequency. The piezoelectric component is driven with the vibration frequency and the vibration time period, such that at least a portion of the foreign substances are removed from the transparent cover through vibration of the piezoelectric component.
