5. Dark signal non-uniformity : DSNU
6. Output impedance : Z
7. Response : R
8. Image lag : IL
Absolute maximum of the difference between ADS and voltage of the highest or lowest output pixel of all the valid
pixels at light shielding. This is calculated by the following formula.
Impedance of the output pins viewed from outside.
Output voltage divided by exposure (lx•s).
Note that the response varies with a light source (spectral characteristic).
The rate between the last output voltage and the next one after read out the data of a line.
