FAR INFRARED IMAGING APPARATUS, PHYSICAL QUANTITY DETECTION METHOD, AND OBSTACLE ESTIMATION APPARATUS AND METHOD

摘要

A far infrared imaging apparatus has an imaging element which generates an image according to infrared rays radiated from an obstacle, a temperature controller which controls the imaging element to be at temperatures different in terms of time, and a detector which detects at least the radiation factor or temperature of the obstacle on the basis of the output of the image generated by the imaging element in each state of being controlled to be at different temperatures by the temperature controller.
