Abstract
A method for monitoring inactive pixels in a scene imaging system may include determining a location of at least one inactive pixel in a focal plane array. The method may include sensing an environment image based upon a surrounding environment of an aircraft. The method may include generating an image associated with the environment image. The method may include evaluating a location for one or more inactive pixels in the generated image in comparison to a location for the at least one inactive pixel in the focal plane array. The method may include determining whether a fault exists in image generation or image display based upon the evaluation.
