DEFINITIONS OF CHARACTERISTIC ITEMS
1.
Saturation voltage: V
sat
Output signal voltage at which the response linearity is lost.
2.
Saturation exposure: SE
Product of intensity of illumination (I
X
) and storage time(s) when saturation of output voltage occurs.
3.
Photo response non-uniformity: PRNU
The output signal non-uniformity of all the valid pixels when the photosensitive surface is applied with the light
of uniform illumination. This is calculated by the following formula.
4.
Average dark signal: ADS
Average output signal voltage of all the valid pixels at light shielding. This is calculated by the following formula.
