An imaging device includes an image sensor, an optical element arranged in front of the image sensor, an electromechanical converter attached to the optical element, and a controller configured to provide a control signal to the electromechanical converter to control a vibration of the electromechanical converter. An amplitude of the control signal has a first amplitude value when a frequency of the control signal has a first frequency value. The amplitude of the control signal has a second amplitude value smaller than the first amplitude value when the frequency of the control signal has a second frequency value that is closer to a resonant frequency of the optical member than the first frequency value.
