Webon photon transfer curves which are also known as mean -variance curves. These curves rely on the discrete nature of photon arrival and the resulting Poisson statistics to empirically determine conversion gain. To extract conversion gain from a mean -varianc e plot, data must have fixed pattern noise (FPN) removed. 1.2 Contributions The Photon Transfer Curve (PTC) is a log‑log plot ofnoise versus signal for a digital sensor. The logarithms are base 10 and the noise and signal units are electrons. This type of plot comes from an engineering tradition and is commonly used todetermine Dynamic Range (DR) Here is a Photon Transfer Curve: Note that … See more The Photon Transfer Curve is of little photographic interestand I prefer to show that same data as a Signal to Noise Ratio (SNR) versussignal plot. Here is such a Signal to Noise Ratio … See more By taking two exposures at each signal level, certain noisesources can be subtracted out; and some other additional values of interest canbe computed. See more With PRNU and other fixed noiseremoved, the resulting data comprises a fixed amount of noise plus photon noise(a type of shot noise). To … See more The noise that is removed has two components, one fixed andthe other linear with signal strength. The fixed noise is mostly dark noise. … See more
