Saturation voltage: V
Output signal voltage at which the response linearity is lost.
Saturation exposure: SE
Product of intensity of illumination (I
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.
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) =
