10. Image lag O/E :
IL-O/E
It is defined as a difference of the average of image lag of odd and even pixels for each color.
11. 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.
12. Total transfer efficiency :
TTE
The total transfer rate of CCD analog shift register. This is calculated by the following formula, it is difined by
each output.
TTE (%) = (1

13. Light shielding random noise :
σ
dark
Light shielding random noise
σ
dark 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).
