REAL-TIME PIXEL SUBSTITUTION FOR THERMAL IMAGING SYSTEMS

A non-uniformity correction (NUC) process for imaging engines is augmented with real-time pixel substitution capability. This feature checks for pixels that have significantly degraded from their factory performance. Degraded pixels found are then substituted in real time. This process eliminates di...

Summary:A non-uniformity correction (NUC) process for imaging engines is augmented with real-time pixel substitution capability. This feature checks for pixels that have significantly degraded from their factory performance. Degraded pixels found are then substituted in real time. This process eliminates distractions to the camera system operator and prevents these degraded pixels from degrading the subjective image quality. L'invention concerne l'amélioration d'un procédé de correction de non-uniformité (NUC) appliqué à des moteurs d'imagerie, concrétisée par la possibilité de substitution de pixels en temps réel. Cette caractéristique détermine les pixels ayant subi une dégradation importante par rapport à leur qualité à la fabrication. Les pixels dégradés détectés sont remplacés en temps réel. Ce procédé permet d'éliminer le risque d'inattention de la part de l'opérateur du système de prise de vues et d'empêcher les pixels dégradés d'altérer la qualité de l'image subjective.
