Abstract
This infrared imaging device includes: an infrared transmission lens which collects infrared light emitted from an object; an infrared imaging element having a screen in which pixels for converting infrared light collected by the infrared transmission lens to electric signals are arranged in a two-dimensional array; a signal processing unit which converts electric signals from the infrared imaging element to digital signals; an optical characteristics correction unit which performs optical characteristics correction for an output of the signal processing unit on the basis of non-image-formation information set in advance for the infrared transmission lens; a reference temperature detection unit which detects a reference temperature; and a temperature measurement unit which performs absolute temperature conversion for the object on the basis of an output of the optical characteristics correction unit and an output of the reference temperature detection unit.
