DEFINITIONS OF CHARACTERISTIC ITEMS

1.

Output signal voltage at which the response linearity is lost.

2.

Saturation exposure: SE

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.

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

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.
