1. A thermal imaging camera comprising: a pixel-based detector unit for a pixel-based recording of thermal radiation of a scene imaged onto same with at least two different sensitivities and alternating reading of more sensitive and less sensitive images; a processor unit for controlling reading, preprocessing, buffering and linking of at least two more sensitive and less sensitive images read alternatingly from the detector unit into a common output image; an image buffering unit comprising a common accumulator for both more sensitive and less sensitive original images and with a common output image available at a buffering unit output; an image weighting unit arranged upstream of the accumulator for a pixel-by-pixel weighting of more sensitive and less sensitive original images read alternatingly from the detector unit and with a settable percentage weighting function and for the pixel-by-pixel weighting of the output image buffered in the accumulator with a weighting function complementary to the settable percentage weighting function as well as for the additive superimposition of the two images for continuous updating of the output image on the basis of original images read alternatingly from the detector unit with at least two different sensitivity settings.
