Note 10

Note)

1. In accordance with the given electrooptical characteristics, the even black level is defined as the average

value of D24, D26 to D52. The odd black level is defined as the average value of D25 , D27 to D53.

2. For the sensitivity test light is applied with a uniform intensity of illumination.

3. Light source: LED λ = 660nm

4. PRNU is defined as indicated below. Ray incidence conditions are the same as for Note 2.

PRNU = (VMAX – VMIN)/2

VAVE

× 100 [%]

Where the 3000 pixels are divided into blocks of even and odd pixels, respectively, the maximum output of

each block is set to VMAX, the minimum output to VMIN and the average output to VAVE.

5. Integration time is 10ms.

6. The difference between the maximum and average values of the dark output voltage is calculated for even

and odd respectively. Integration time is 10ms.

7. Typical value is used for clock pulse and readout pulse. VOUT = 500mV.

VSAT

8.

DR = VDRK

When optical integration time is shorter, the dynamic range sets wider because dark voltage is in

proportion to optical integration time.
