PROBLEM TO BE SOLVED: To provide an infrared camera for preventing the failure of an infrared imaging part due to imaging the image of a high luminance object or a high temperature object. SOLUTION: This infrared camera is provided with: an infrared imaging part for converting received infrared rays of light into an electric signal corresponding to intensity; a shutter mechanism for interrupting the rays of light made incident from the outside to the infrared imaging part; an optical diaphragm mechanism for controlling the diaphragm of the rays of light made incident from the outside to the infrared imaging part; an image signal generation part for generating an image signal by processing a signal acquired by amplifying the electric signal from the infrared imaging part by a first gain, and A/D converting it; and an incident light control signal generation part for amplifying the electric signal from the infrared imaging part by a second gain which is lower than the first gain, and for A/D converting it, and for transmitting an incident light control signal to the shutter mechanism or the optical diaphragm mechanism for interrupting or reducing the rays of light made incident from the outside to the infrared imaging part when the A/D converted infrared signal is turned to be a predetermined threshold or more.
