INFRARED THERMAL IMAGE DEVICE WITH DEVICE FOR UPDATING AN IRREGULAR COMPENSATION TABLE WITHOUT ADDITIONAL EQUIPMENT

摘要

PURPOSE: A thermal image device is provided to update an irregular compensation table inside the thermal image device without using an additional device. CONSTITUTION: A temperature reference unit(460) adjusts a temperature as a temperature indicated by a control unit(440). Temperature reference driving units(450,470,480) locate the temperature reference unit in a basic position not to cover a lens unit(410) or in front of the lens portion by driving the temperature reference unit through the control unit. The control unit controls the temperature of the temperature reference unit and the temperature reference driving unit and sends the temperature of the temperature reference in front of the lens portion to a signal processor(430). Thereby, the irregularity is compensated quickly.
