Abstract
The present invention is directed to a thermographic camera and to a method for generating thermal images with this thermographic camera as is described generically in DE 698 30 731 T2. The object of the invention is to provided a possibility for achieving an optimal signal resolution at low object temperatures in an economical manner without signal overload at high temperatures. This object is met by a method for the recording and reproduction of thermal images of a scene and/or of an object, comprising the following steps: a pixel-based thermal image frame is generated by means of IR optics and a pixel-based detector unit; a dark image is generated for implementing a non-uniformity correction (NUC) to eliminate non-uniformities arising from the detector and/or disturbance sources in the optical beam path; the existing pixel-based thermal image frame is corrected by weighting the individual pixel signals with a nonlinear characteristic line which is generated and stored beforehand for generating a corrected output thermal image; and finally, the corrected output thermal image is supplied to a display unit or to an interface for external equipment.
