Black Reference Sequence

Understanding Black Reference

A black reference is the process of reading the sensor output 
during an exposure without the sensor being exposed to 
light. This data is written to the camera and used to subtract 
from the regular capture. 

Updating the black reference data whenever it is possible 
enhances the image quality, in particular when shooting in 
conditions where the temperature of the camera changes. If 
the exposure time varies a lot, the black calibration reference 
data should be updated.

It is advisable to make a black reference capture before 
starting your first flight line and if the exposure settings 
or ISO have been changed. This ensures the accuracy of 
exposures. The best time to do this is before starting a new 
flight line, when images are not being captured.

Note: Black reference is performed automatically on taking 
the first shot after switching the camera on.

Hardware Activation of Black Reference

If you are building your own hardware control box, you can 
update the black reference data in the camera. The black 
reference control signal should be kept low while an image 
capture cycle is initiated. The signal must remain low for the 
full capture cycle. This makes it possible to create a black 
reference whenever it is convenient (i.e. when turning an 
aircraft around or between flight lines). When the force black 
signal is kept high, the camera uses the last updated black 
reference data.

Software Activation of Black Reference

The Phase One iXU-RS/iXU-R/iXU camera can perform 
a black reference sequence by using the iX Capture 
application, the Phase One SDK, the Flight Management 
System or through an iX Link API. 

When using iX Capture, simply click Black Ref on the iX 
Capture dashboard to update the black reference.

Wiring a Control Cable for an iXU Series 
Camera

External devices are connected to the camera with an iXU 
RA control cable (supplied with the camera kit). This cable 
has a LEMO-secured connector on one side for the camera 
and an open side with nine (28 AWG) wires for connection to 
your system. 

The table below describes the functionality of the wires in 
the iXU RA control cable.
