DEFINITIONS OF CHARACTERISTIC ITEMS
16
1. Saturation voltage : V
2. Saturation exposure : SE
3. Photo response non-uniformity : PRNU
4. Average dark signal : ADS
Output signal voltage at which the response linearity is lost.
Product of intensity of illumination (lx) and storage time (s) when saturation of output voltage occurs.
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 (%) =
Average output signal voltage of all the valid pixels at light shielding. This is calculated by the following formula.
ADS (mV) =
