Abstract

A conceptual real-time structure for driving and image enhancement of a Cooled Infrared Focal Plan Array with 320×240 detectors will be discussed. It is the case that a mechanism for Non-Uniformity Correction between the sensitive elements needs a structure for compensation of gradual drift in the detectors' output by update the correction factors in a regular way. A feasible method, Least-Mean-Square, under a compact hardware is introduced. Inherently, the intended detector has not a suitable timing for sending out for standard display equipments, so it is essential to have hardware for frame-to-frame processing. Applying a capability of the sophisticated FPGAs, the contrast enhancement based on Bi-Histogram Equalization which preserves the brightness of infrared image effectively is described.
