Abstract
Plateau Equalization (PE), automatically optimizes, tracks changes in luminance, and adjusts in real time the display of wide dynamic range imagery from infrared cameras. The PE approach includes an automated contrast control system which uses an infrared camera, a microprocessor, and an 8 bit monitor to display the IR scenes with automatic control of the contrast of the IR data. This system allows 8 bit monitors to be used with 12 bit cameras. The camera acquires IR data which is digitized for the microprocessor. The microprocessor processes the IR data with a plateau equalization program to output digital IR data for the monitor with controlled contrast. The monitor displays the output of the microprocessor. Plateau Equalization occurs as peaks in infrared data are cut off into an assigned plateau value so that the display allocation emphasizes smaller features of interest in the scene and remains immune to flicker noise.
