The possibility of reducing the influence of synchronous and asynchronous noises on the termovisions based cameras on pirovidikon by introducing into it the second receiving channel. The variants of the construction of a thermal imaging camera video processor. The proposed scheme provides effective noise suppression, work in real time and can be used to form a stereoscopic thermal object.
