9. Register imbalance: RI
10. Random noise: σ
The rate of the difference between the averages of the output voltage of Odd and Even pixels, against the
average output voltage of all the valid pixels.
Random noise σ is defined as the standard deviation of a valid pixel output signal with 100 times (=100 lines) data
sampling at dark (light shielding).
This is measured by the DC level sampling of only the signal level, not by CDS (Correlated Double Sampling).
