Abstract: A driver for a liquid crystal lens, an imaging apparatus and a temperature controlling method thereof, include: a liquid crystal lens which adjusts a focal length according to a voltage applied thereto; a lens driver which applies the voltage to the liquid crystal lens; a sensor driver which detects a temperature of the liquid crystal lens, compensates for the detected temperature, and determines whether the compensated temperatures maintains a preset range for the driver for the liquid crystal lens to perform a control operation; and a heater driver which, according to the determination by the sensor driver, controls heat generation of the liquid crystal lens to maintain a temperature of the liquid crystal lens in the preset range. Thus, the driver detects a temperature of the liquid crystal lens accurately by compensating for a resistance value from the liquid crystal lens to thereby maintain stability of the imaging apparatus.
