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 peak/bottom ratio to the average output voltage of all the valid pixels calculated by the following formula.

PRNU (%) =

VMAX. or VMIN. − 1

4. Average dark signal : ADS

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

formula.

5. Dark signal non-uniformity : DSNU

The difference between ADS and voltage of the highest or lowest output pixel of all the valid pixels at light

shielding.
