Structure of the Sensor
Full Exposure Control
As the « Full Definition Enhanced » color mode is performing an internal Time delay exposure on the Four
Color lines, normally, the variation of the Exposure time should not possible in this sensor mode.
Thanks to an e2v licensed solution, two of the Exposure controlled mode (Ext Trig with internal or
External exposure control) are still available in this color mode.
The “Free Run” synchronization mode (line Trigger and Exposure time controlled internally) is not
available in the “FDE” color mode.

In Full Enhanced, each color is issued
from the summation of 2x pixels (with
a delay between each exposure)

Blue and Red are issued from the binning
of 2 pixels.. Green is calculated from the
averaging of 2x 2 pixels binning (G

)
