To provide an infrared radiation imaging device capable of adjusting a composite ratio of a visible light component and an infrared component when imaging is executed under low illuminance.
In executing imaging under an infrared radiation imaging condition, an infrared combined imaging device processes white balance per color of an imaging signal generated under visible light imaging condition in which an infrared cut filter is inserted into an optical path, and generates a white balance imaging signal. The imaging device separates an imaging signal generated under the infrared radiation condition into a visible light component signal and an infrared component imaging signal, generates a visible light luminance signal and a chroma image signal from the visible light component imaging signal, and generates an infrared luminance signal from the infrared component imaging signal. The imaging device adjusts the composite ratio of the visible light luminance signal and the infrared luminance signal to generate an luminance image signal.
