1. For the sensitivity test light is applied with a uniform intensity of illumination.
2. Light sourse: LED λ = 660nm
3. PRNU is defined as indicated below. Ray incidence conditions are the same as for Note 1.

PRNU = × 100 [%]
(VMAX – VMIN)/2
VAVE
The maximum output of all the valid pixels is set to VMAX,
the minimum output to VMIN and the average output to VAVE.
4. Integration time is 10ms.
5. Typical value is used for clock pulse and readout pulse. VOUT = 500mV.
6. DR =
VSAT
VDRK
When optical integration time is shorter, the dynamic range sets wider because dark voltage is in
proportion to optical integration time.
