An infrared camera capable of automatically executing offset compensation so that fixed pattern noise is removed without the need of an operator comprises an offset compensation signal generation circuit and a shutter. The shutter is closed based on an offset compensation execution signal for carrying out offset compensation, the signal being automatically and periodically generated by the offset compensation signal generation circuit after execution of the first offset compensation.
