Thermovision cameras, based on pyrovidicon, are widely used in thermal phenomena investigation including applied mechanics. It is known that pyrovidicon target has the effect of charges appearance under machanical influences. As a result, special noises aggravate the quality of thermographic images. Besides external sources of mechanical influences, some influences may be generated by thermovision camera units that ensure action of obturator. The last is the integral part of pyrovidicon camera. Peculiarities of mentioned influence and details of their sources are discussed in the paper. Special processor for these influences decrease is proposed. Image quality enhancement is based on pyrosignal processing by that processor. The nature of influences and results of signal processing are illustrated. The structure of the processor is shown
