3—Basic Operation of the Tau and GUI
Tau displays an on-screen symbol called
the Flat Field Imminent Symbol prior to
performing an automatic FFC operation.
As shown in Figure 3-4, it is the green
square in the upper left of the video
output and is displayed nominally 2
seconds prior to the FFC operation. The
duration of the FFC Imminent Symbol
can be set using the FFC Warn Time
setting in the Analog Video tab. Setting
the Warn Time to zero turns off the
warning (see paragraph 3.9).
External Sync Mode:
camera provides the ability to either accept or output a
frame synchronization signal. This functionality can also be
disabled.
Disabled: The camera will turn off frame synchronization.
Slave: The camera will accept a frame synchronization signal on the interface
connector. The camera output will be frozen if the camera is in slave mode and no
external synchronization signal is received.
Master: The camera will output a frame synchronization signal on the interface
connector when configured as a master.
Operating Mode:
The Tau camera will freeze the
frame imaged when Frozen is selected. Live video will cease
and the frozen frame will persist. To return the camera to
live video, select Real-Time video mode.
Save Settings:
After using the FLIR Camera Controller to change
camera modes and settings to your desired values, use the Save Settings
button to store your current selections as new power-up defaults. The next
time the camera is powered, the Tau camera will remember these saved
settings. If you do not click Save Settings, the changes you make via the FLIR Camera
Controller will be valid only for the current session. Cycling power to the camera will revert to
the previously saved settings.
Factory Defaults:
settings to the initial values specified by the manufacturer.
If you want the factory default settings to become the power up defaults, first
click the Factory Defaults button, then click the Save Settings button.
Reset Camera:
The Reset Camera button restarts the camera software
and is nearly identical to cycling power.
