Web1 jul. 2007 · For a camera, the number of photons required to achieve saturation is the saturation capacity/QE. For a camera that requires 20,000 photons to reach saturation at a QE of 50% (0.5), the number of photons will be 40,000. Since the noise is given as the SQRT (signal) = SQRT (40000) = 200, the S/N = 40000/200 = 200 = 46 dB or 7.6 bits.
