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 (%) = ∆x × 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.

ADS (mV) =
5300
dj : Dark signal of valid pixel number j
5. Dark signal non-uniformity: DSNU
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.
DSNU (mV) : maximum of dj − ADS j = 1 to 5300
dj : Dark signal of valid pixel number j
