Flat Field Correction on Thermal Cameras
The thermal camera uses an internal process called flat-field correction (FFC) to improve the
quality of the thermal video image displayed on the monitor. During this process, a shutter
rotates in front of the Focal Plane Array (FPA) to give a uniform temperature (a flat field) to
every detector element. During the process (which takes less than a second), the live thermal
video image is frozen, and persists, while the camera updates correction coefficients. After the
process completes, live video returns automatically. With a more uniform array output, the
quality of the image should improve.
When the camera is powered on initially, the interval between FFC events ranges from 1
minute to 3 minutes. This frequency of FFC events ensures that the thermal imager will be
corrected more often while the internal temperature of the camera stabilizes. After several
minutes of camera operation, the interval between FFC events is approximately 6 minutes.
In case of constant motion in the scene, FFC may be delayed up to 12 minutes.
