6. Output impedance: ZO
Impedance of the output pins viewed from outside
7. Response: R
Output voltage divided by exposure (lx•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. Register imbalance: RI, RI-FR
RI is the rate of the difference between the averages of the output voltage of odd pixels and even pixels, against the
average output voltage of all the valid pixels. The RI is calculated between VOUT1 and VOUT2 and between VOUT3 and
VOUT4. The RI-FR is defined as RI between Front and Rear.
