1. Automatic. In the Automatic FFC mode, the camera performs FFC whenever its
temperature changes by a specified amount or at the end of a specified period of time
(whichever comes first). When this mode is selected, input windows are available on the
Control Panel for specifying the temperature change and the number of frames that
trigger automatic FFC. The temperature change is specified in degrees, with valid values
in the range 0 to 100 in 0.1 degree increments. The time period is specified in frames,
with valid values in the range 0 to 30,000 frames.
Note: It is recommended to use the factory default values for the two automatic-FFC
parameters if possible. These values were selected to maintain a high degree of image
quality over all camera operating conditions.
2. Manual. In Manual FFC mode, the camera does not perform FFC automatically based on
specified values of temperature change or expired time.
Note: Even in manual FFC mode, Photon will perform automatic FFC when it changes
between low-temperature and high-temperature states. Furthermore, as the camera is
heated or cooled during operation, it will perform FFC automatically when its temperature
crosses through the different Non-Uniformity Correction tables.
On-Screen-Symbol: Photon uses on-screen symbols for displaying important camera status.
Specifically, the following indicator is provided:
a. FFC Imminent: displayed nominally 2 seconds before automatic FFC.
Figure 9 shows the approximate size and location of this indicator on the display.

Digital Output Modes: The Photon provides a digital data channel with four selectable
modes:
