US Patent 8212210 IR camera and method for presenting IR information

A camera arranged to generate an IR image and a visible light image is proposed, said camera comprising a thermal imaging part for registering IR radiation from a first field of view, a visible light imaging part for registering visible light from a second field of view at least partially overlapping with the first field of view, and a processing device for processing the information related to the registered IR radiation and the registered visible light information. The processing device is arranged to identify any moving objects that are detectable by the thermal imaging part and not by the visible light imaging part, and presenting said moving objects, if any, in such a way that they will be easily recognizable by an operator.
