calibration is made while using an 8-bit buffer, then there will be missing coefficients if the user
changes to a 12-bit acquisition.
A Sapera application (such as CamExpert) creates a new SapBuffer object of the same width as the
sensor but with twice the number of lines. This provides the room to store both offset and gain Flat
Field data. The Flat Field offset data is contained in the top half of the new buffer, while the gain
buffer is in the bottom half.
A Sapera application saves the new buffer using SapBuffer::Save with the "-format tiff" option,
which allows saving data without loss of significant bits.
Important Factors about Flat Field Processing
Important: Before calibration, the Linea GigE should be powered on long enough to achieve its nominal
temperature (a minimum of 30 minutes). A low ambient temperature may increase the time required for the
camera to reach a stable internal temperature.
Important: During calibration, no other Linea GigE features should be accessed or modified.
Calibration via CamExpert or via a User Application: Exposure and frame rates used during a Flat Field
Calibration should be similar to the exposure settings used in the camera application.
