The FFC in thermal cameras is a mechanism that periodically corrects the image quality in order to prevent it from deteriorating over time. During this process the image may freeze for about 2 seconds and will show a static image. Once the process is completed, the image is automatically recovered. This process can prevent image graining and degradation problems.
In Sunell cameras, the FFC process is performed every X amount of time, or when there is a sudden temperature change in the image, which will cause a change in the colors presented. Both the time and the temperature change necessary for it to be executed can be modified, although it is not recommended to do so, by right-clicking on the live image:
It is also possible to reset the FFC, this can be interesting in cases where it is detected that the image presents a deterioration, or a halo that remains when moving the camera
For those cases in which the camera is NOT going to be used to control the temperature, it is suggested to deactivate this measurement, since it may happen that the image may deteriorate eventually, and deactivating it can be avoided:
