Calibration Tab
When the FLIR Camera Controller GUI successfully links to the camera, the window shown below will be
visible. At the bottom of the application window, there is the Camera and FPA status. The GUI provides
six tabs allowing for camera control as described below.

Integration Time:
The
Integration Time text box is used to set the integration time in milliseconds.
The integration time is similar to the exposure time of a standard daylight camera and is the time
per frame during which charge is collected. The camera operates in “snapshot” mode, meaning
that charge is collected on the entire array of pixels at the same time. Integration times may be set
as low as 0.010ms, while the upper limit depends on the frame rate and is limited to about 0.032ms
less than the frame period, about 16 milliseconds in 60fps mode or 33ms in 30fps mode . Short
integration times should be used for viewing very bright objects, while long integration times are
used for low illuminiation conditions. If integration times that are too short or too long are used,
the image will appear non-uniform and will seem to be non responsive to the signal, so some
experimentation is required to determine the best integration time for the scene being imaged.
Using the
Image Mean Intensity
feature will assist in determining the best integration time. An
integration time resulting in good imagery for a typical application is when the camera is “looking”
at the scene of interest and the image mean intensity is between 3000 and 6000 counts.
Note: In order to manually select values for integration time, Auto-Exposure,
located on the Optimization tab, must be disabled.
