Flat Field Correction (FFC) controls how the camera regularly adjusts its thermal settings to optimize its image. This process takes about 0.5 seconds. During this process, there may be a lag in image quality.

Before performing the FFC process, the camera warns the operator by displaying a small blinking box in the upper left corner. This indicator appears for 2 seconds.

You can delay the FFC process at any time. Press the Iris Close button to delay the FFC for at least one minute. Use the delay option when you are observing activity that would be interrupted by the FFC process.

The following sections describe how to use each FFC option.

FREQUENCY

Frequency controls how often the camera performs the FFC process, regardless of the temperature change in the field of view. After each FFC, the camera restarts the frequency clock.
