Summary: | An imaging device may have an array of image pixels that includes red, green, blue, and infrared pixels. The imaging device may include a dual-band filter that allows transmission of light in the visible band and in the near-infrared band and may include color processing circuitry that produces a color image with marked infrared regions. The color processing circuitry may include a standard color processing pipeline with a color correction matrix that produces a tone-mapped standard red, green, and blue image and may include infrared marking circuitry. The infrared marking circuitry may include hue angle determination circuitry, cell means determination circuitry, and near-infrared determination circuitry that determine portions of the image with high infrared reflectance to be marked. The infrared-marked tone-mapped standard red, green, and blue image may be output to a machine vision system to identify objects in the imaged scene with high infrared reflection. |
