Paper Abstract

A flexible and real-time structure in hardware and software intended for driving a 320×240 detectors Infra-Red Focal Plan Array (IRFPA) is presented. The most critical case in the image detectors based on array elements is the Non-Uniformity Correction (NUC) between the sensitive elements due to the different characteristics of the materials in fabrication phase, especially for the IRFPAs with high elements and low cost ones which their non-uniformities are inherently more severe. Feasible NUC method of detectors and steps for implementation of an effective strategy for calibration of NUC factors by employment of the Least-Mean-Square method under a very compact hardware is discussed. A real-time method for contrast enhancement under a statistical approach by referring to Bi-Histogram Equalization which preserves the brightness of infrared images from theory to implementation on the Spartan family by arranging an adaptive Look-Up Table is manifested.
