4.7 Parameter Window
Cheetah Cameras have many features that can easily be programmed using the Cheetah
graphical user interface (GUI) or via simple register commands using the Command
Terminal. The main parameter windows are described below.
4.7.1 Dual Video (Frame A / Frame B) Window
4.7.1.1 Dual Video Controls:
Frame A / B window allows the user to set up two independent acquisition setups (Frames)
and the conditions under which the camera switches between these two independent
camera configurations.
Figure 37: Frame A/B Options Menu.
4.7.1.2 Output Mode:
Frame A:
outputs video according to the Frame A settings.
Frame B:
outputs video according to the Frame B settings.
Dual Video:
the cameras outputs ‘M’ Frame As followed by ‘N’ Frame Bs then repeats this
sequence. ‘M’ and ‘N’ are values between 1 and 256. In the above graphic, Dual Video is
selected and M is set to 3 and N is set to 1. If trigger is enabled, the camera waits for trigger,
then outputs ‘M’ Frame As followed by ‘N’ Frame Bs and then awaits the next trigger.
Dual Video Trigger:
the camera outputs Frame As continuously. Upon receipt of trigger, the
camera outputs ‘N’ Frame Bs and then returns to outputting Frame A’s.
Shutter Mode:
Selects Shutter mode. Global shutter for objects in high speed motion or rolling shutter for
best dynamic range and lowest possible noise floor.
ADC Selector
: Selects image sensor digitization level. 12-bit digitization requires longer
settling time and impacts maximum camera frame rate. 10-bit digitization provides higher
maximum frame rates.
DV Line Time:
In Dual Video mode, line time controls for Frame A and Frame B are disabled. The dual video
line time control sets the line time for both Frame A and Frame B captures.
4.7.1.3 Exposure Controls
This window controls the camera exposure, line and frame time.
