6. Output impedance: ZO
Impedance of the output pins viewed from outside.
7. Response: R
Output voltage divided by exposure (Ix•s).
Note that the response varies with a light source (spectral characteristic).
8. Image Lag: IL
The rate between the last output voltage and the next one after read out the data of a line.

9. 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).

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