Note

1) In accordance with the given electrooptical characteristics, the black level is defined as the average value of D2, D3 to D12.

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

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

VOUT-G = 500mV (Typ.) PRNU = × 100 [%]

Where the 2700 pixels are divided into blocks of 100. The maximum output of each block is set to VMAX, the minimum output to VMIN and the average output to VAVE.

4) Use below the minimum value of the saturation output voltage.

5) Saturation exposure is defined as follows.

SE =

Where R indicates RR, RG, RB, and SE indicates SER, SEG, SEB.

6) Optical signal accumulated time τ int stands at 10ms.

7) VOUT-G = 500mV (Typ.)

8) Vos is defined as indicated bellow. VOUT indicates VOUT-R, VOUT-G, and VOUT-B.

9) Dynamic range is defined as follows.

DR =

When the optical signal accumulated time is shorter, the dynamic range gets wider because the optical signal accumulated time is in proportion to the dark voltage.
