10. Register imbalance :
RI
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.

This is measured by the DC level sampling of only the signal level, not by CDS (Correlated Double Sampling).
12. Shot noise :
σ

Shot noise is defined as the standard deviation of a valid pixel output signal with 100 times (= 100 lines) data
sampling in the light. This includes the random noise.
The formula is the same with that of random noise.
