Flat-Field Calibration of Image in Multi-Exposure Mode
Performing a flat-field calibration while in multi-exposure mode results in the camera automatically
setting both lines of the sensor to the same integration time. Both lines will be flat-fielded to the target
value provided. After the flat-field calibration has completed the integration and gain values are reset to
the lines that they were set to prior to the flat-field request.
In the above example the flat-field target was set to 200 DN, based on the image on the left-hand side. The
integration time for the image on the right was automatically set the same as the image on the left during
the flat-field process. After the flat-field process had completed, the image on the right-hand side had its
selected integration time restored to its pre-calibration value, which is why it appears darker than the left
side.
Flat-Field Region of Interest
While in multi-exposure mode, setting up a flat-field region of interest results the same region of interest
coordinates to be applied to both lines.
