Abstract
A heat source detection device includes a processor configured to calculate, as a single-wavelength temperature, one of a first temperature obtained by converting a first output output from the infrared sensor in accordance with an incident amount of infrared rays in a first infrared wavelength band into a temperature, a second temperature obtained by converting a second output from the infrared sensor in accordance with an incident amount of infrared rays in a second infrared wavelength band into a temperature and an average value of the first and second temperatures, and calculate a dual-wavelength temperature obtained by converting the ratio between the first and second outputs into a temperature; and to determine a temperature of the heat source based on the dual-wavelength temperature and determine a distance to the heat source from the infrared sensor based on a comparison result between the single-wavelength temperature and dual-wavelength temperature.
