Claim 10:
11. A method of operating an imaging system, the method comprising:
producing an image using an image sensor having repeating unit cells of pixels, including infrared pixels;
performing color processing on the image to produce a color tone-mapped image with near-infrared color artifacts;
determining image regions having a hue angle within an expected range, including determining the hue angle based on the color tone-mapped image with the near-infrared color artifacts;
determining image regions within a selected signal range;
determining image regions with a near-infrared ratio above a threshold; and
marking regions of the tone-mapped image that have the hue angle within the expected range, fall within the selected signal range, and are above the near-infrared ratio threshold.
