DEFINITIONS OF CHARACTERISTIC ITEMS
1. Saturation voltage: Vsat
Output signal voltage at which the response linearity is lost.
2. Saturation exposure: SE
Product of intensity of illumination (IX) 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.
PRNU (%) = ^Δx × 100

4. Average dark signal: ADS
Average output signal voltage of all the valid pixels at light shielding. This is calculated by the following formula.
