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 (lx) and storage time (s) when saturation of output voltage occurs.
3. Photo response non-uniformity :
PRNU
The peak/bottom ratio to the average output voltage of all the valid pixels calculated by the following formula.
V
MAX.
or V
MIN.
j = 1
PRNU (%) =
n : Number of valid pixcels
V

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