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) = ^,x ´ 100 (%)
x
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 = 1/2·SE
Green = 1/2·SE
Blue = 1/4·SE
Note 4: PRNU (3) is defined as maximum voltage with next pixels, where measured at 5% of SE (typ.).
Note 5: Register imbalance is defined as follows.
