Abstract
An infrared detection apparatus includes an infrared detector configured to output an electric signal corresponding to an inputted infrared ray, and a signal processor configured to compensate for a variation of the electric signal, which is outputted from the infrared detector, caused by variation of an operation temperature with a value indicating a variation of a dark current equivalent component by the operation temperature variation when becoming a second operation temperature after the operation temperature variation, the dark current equivalent component including a first dark current equivalent component calculated using a first electric signal and a second electric signal outputted from the infrared detector when infrared rays having intensities equivalent to blackbodies of a first known temperature and a second known temperature are inputted at a first operation temperature.
