Flat Field Correction (FFC)
A flat field correction is an offset calibration that is triggered at powerup, after a certain
change in temperature, and periodically throughout the camera operation. The purpose of
the calibration is to compensate for certain errors that build up during camera operation.
Ultimately, this improve the image quality by removing noise and other artefacts that may appear
during use. The TZ20 is always in auto FFC mode, but a manual trigger can be triggered by pressing the
button.
AGC Lock/Unlock
The AGC Lock allows the image to hold a constant temperature-to-color pallet in a dynamic
moving scene. This allows the user to identify objects in the camera field of view with
specific IR radiation and facilitates locating items in specific scenes.
