Abstract: A nonuniformity correction processor (30) adapted for use with a focal plane array of detectors. The inventive processor (30) includes a nonuniformity correction circuit (32, 38, 42, 53, 54, 56, 58) for generating current nonuniformity correction terms (32) and applying the terms to information (26) received from the scene via the focal plane array of detectors. A triggering circuit (44) selectively enables the nonuniformity correction circuit (32, 38, 42, 53, 54, 56, 58) in response to a motion signal (50) from a motion detector (40, 46, 48, 52). In a specific embodiment, the nonuniformity correction circuit (32, 38, 42, 53, 54, 56, 58) further includes a filtering circuit (38) for generating intermediate nonuniformity correction terms (42, 53) in response to the scene information (26) received from the focal plane array of detectors.

Abstract: A modular signal processing architecture adapted for use with a focal plane array of detectors. The inventive architecture includes an analog signal processing module (42) for adjusting signals from the focal plane array (12). A nonuniformity correction module (44) provides signal adjustment parameters to the analog signal processing module (42) for each of the detectors in the array (12). A control module (80) provides control signals to each of the modules in the system as required for a desired system configuration. In a specific embodiment, the control signals are communicated via programmable registers on each module. Software running on the system control module provides the control signals to the programmable registers to reconfigure the system in response to the addition of modules thereto. Hence, additional modules may be easily incorporated into the system without a costly redesign of same.
