Abstract

This paper analyzes the various factors contributing to the performances of the FLIR, and describes a series of solutions to control its transfer function and improve its performance. The paper describes the camera concept, elaborating on its behavior and associated control functions in the time domain, on the two dimensional image domain, and on the signal model translation to standard video signal. The camera contains the following blocks : A. Time domain low pass filter that is controlled in real time according to the velocity of the objects observed B. Two dimensional high pass filter that is controlled in real time according to SNR of the input video signal, C. Supplementary filter that removes the 1/f noise, controlled according to the SNR of the input video signal, D. An automatic controlled dynamic range compression mechanism.
