Notes
1) In accordance with the given electrooptical characteristics, the even black level is defined as the average
value of D6, D8, to D24. The odd black level is defined as the average value of D5, D7, to D23.
2) For the sensitivity test light is applied with a uniform intensity of illumination.
3) W lamp (2854K)
4) PRNU is defined as indicated below. Ray incidence conditions are the same as for Note 2.
V
OUT
= 500mV (Typ.)
PRNU =
100 [%]
Where the 5150 pixels are divided into blocks of even and odd pixels, respectively. The maximum output of
each block is set to V
MAX
, the minimum output to V
MIN
and the average output to V
AVE
.
5) Use below the minimum value of the saturation output voltage.
6) Saturation exposure is defined as follows. SE = V
SAT
/R1
7) RI is defined as indicated bellow. V
OUT
= 500mV (Typ.)
RI =
100 [%]
Where average of odd pixels output is set to V
ODD-AVE
, even pixels to V
EVEN-AVE
.
8) Optical signal accumulated time
int stands at 10ms.
9) The difference between the maximum and average values of the dark output voltage is calculated for even
and odd respectively. The larger value is defined as the dark signal nonuniformity.
Optical signal accumulated time
int stands at 10ms.
