TCD2558D
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) = ^Dc ´ 100 (%)
c
When ? is average of total signal output and Dc is the maximum deviation from ?. 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 5% of SE (typ.).
Note 5: Image lag is defined as follows.
Note 6: V_SAT is defined as minimum saturation output of all effective pixels.
Note 7: Definition of SE
SE = ^VSAT (Ix × s)
R_G
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.
Note 9: DC signal output voltage is defined as follows.
Reset noise voltage is defined as follows.
