Abstract
An embodiment of the present invention comprises: a lens assembly including a liquid lens; a temperature sensor sensing the temperature of the liquid lens; an image sensor receiving light passing through the lens assembly; a detection unit detecting a first driving signal applied to the liquid lens so as to adjust an interface of the liquid lens; and a determination unit comparing the temperature with a target temperature to provide a heating signal to a heater for adjusting the temperature of the liquid lens or to provide the temperature to a compensation unit. The compensation unit discloses a camera module generating a second driving signal which readjusts the interface of the liquid lens by compensating the temperature to the first driving signal.
