  • Patent number: 8619164
    Abstract: Systems and methods for reconstructing pixel values at bad (i.e. fully or partially defective, saturated, and/or non-responsive in one or more spectral bands) pixel locations in multi-spectral photo-detectors are provided herein. A detector having pixel locations responsive in two or more spectral bands may have pixel values at bad pixel locations reconstructed from adjacent pixel location band ratios so long as the bad pixel location is operational/responsive in at least one spectral band. Pixel locations may be two (or more) color pixels, stacked FPAs, “virtual” locations created by mapping pixels in a first detector to pixels in a second detector, or “super pixels” defined on a detector with a patterned band-pass filter.
