1. A system comprising:
an image sensor comprising a first pixel, a second pixel, a third pixel, and a fourth pixel; and
a pixel-level broadband infrared cutoff filter that covers the second pixel and that is configured to prevent the second pixel from collecting infrared light having wavelengths included in a first range of wavelengths;
wherein the first, third, and fourth pixels are not covered by pixel-level broadband infrared cutoff filters configured to prevent the first, third, and fourth pixels from collecting infrared light having wavelengths included in the first range of wavelengths; and
wherein the system further comprises a narrowband infrared cutoff filter that covers the first, third, and fourth pixels and that is configured to prevent the first, third, and fourth pixels from collecting infrared light having a wavelength included in a second range of wavelengths, the second range of wavelengths included in and narrower than the first range of wavelengths.
