Abstract. Infrared image correction for non-uniform sensitivity of separate elements in linear photodector array using statistical real-time analysis of the images is considered. Comparison is performed of adaptive methods (based on analysis of a neighborhood of corrected element) and non-adaptive approaches (employing statistics of intensity distribution throughout the entire frame). A multi-point correction method is suggested which involves an approximation of characteristic curves of photo detector elements.
