Note 2: Sensitivity is defined for each color of signal outputs average when the photosensitive surface is applied
with the light of uniform illumination and uniform color temperature.
Note 3: PRNU (1) is defined for each color on a single chip by the expressions below when the photosensitive
surface is applied with the light of uniform illumination and uniform color temperature.
PRNU
(1)
=
DX
X
´
100
(%)
Where X is average of total signal output and DX is the maximum deviation from X . The amount of
incident light is shown below.
Red = 1/2ï½¥SE
Green = 1/2ï½¥SE
Blue = 1/4ï½¥SE
Note 4: PRNU (3) is defined as maximum voltage with next pixel, where measured at 5% of SE (typ.)
Note 5: Register imbalance is defined as follows.
10799
Ã¥ ^{xn - x (n + 1)}
RI = ^{n = 1}
10799 * X
*100 (%)
Note 6: V_SAT is defined as minimum saturation output of all effective pixels.
Note 7: Definition of SE

Note 8: V_DRK is defined as average dark signal voltage of all effective pixels.
DSNU is defined as different voltage between V_DRK and V_MDK when V_MDK is maximum dark signal
voltage.
