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 (%) =
