9.
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.
n : Number of valid pixels
V
j
: Output voltage of each pixel
10. Random noise:
σ
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).
V
i
: A valid pixel output signal among all of the valid pixels
This is measured by the DC level sampling of only the signal level, not by CDS (Correlated Double Sampling).
