Claims

[Scope of utility model registration request]

an optical system that captures an infrared image of a subject; a two-dimensional infrared imaging device installed on an imaging surface of the optical system; a temperature detection section built in an unused pixel portion of the two-dimensional infrared imaging device; an imaging device holding section that holds a two-dimensional infrared imaging device; a cooling section connected to the imaging device holding section; and a temperature signal processing section that processes the temperature detection signal of the two-dimensional imaging device obtained by the temperature detection section. a control unit that compares the output of the temperature signal processing unit with a preset target temperature and generates a control signal to the cooling unit so that the temperature of the infrared imaging element reaches the target temperature; An infrared imaging device including a video signal processing section that processes video signals obtained by the element.
