An embodiment is a camera module comprising: a lens assembly comprising a liquid lens which comprises a first liquid and a second liquid forming an interface with each other; a temperature sensor for sensing the temperature information of the liquid lens; a controller for adjusting the interface by applying a driving signal to the liquid lens; and a compensation unit for outputting, to the controller, feedback information in which the inclination of the diopter of the liquid lens with respect to the driving signal is proportional to the temperature in a first area and the inclination of the diopter of the liquid lens with respect to the driving signal is inversely proportional to the temperature in a second area which differs from the first area.
