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 (lx) 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, and it is defined by each six of them.

4. Average dark signal : ADS

Average output signal voltage of all the valid pixels at light shielding. This is calculated by the following

formula, and it is defined by each six of them.
