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. 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.
