PURPOSE: A method for controlling multiple temperatures of a non-cooling thermal imaging device is provided to improve low-temperature and high-temperature characteristics of the thermal imaging device by widening a temperature control range of a TEC(Thermo-Electric Cooler) and reducing a difference between a TEC setting temperature and a surrounding temperature. CONSTITUTION: The temperature of the current environment is sensed(300). The sensed temperature is compared with a predetermined plurality of reference temperatures to select a reference temperature of the most similar to the sensed temperature(301,302,303,304,305). The selected reference temperature is set as the operating temperature of a thermal imaging device(306).
