ABSTRACT:
Systems for improving the quality of video images generated by a forward-looking infrared detector array include mechanisms for dynamically adjusting the output signals from one or more non-linear detectors in such an array. These systems and methods utilize the output signals from two or more detectors adjacent to each non-linear detector to provide accurate DC restoration to the signals from such non-linear detectors.
