On this tab the user can define all settings regarding capturing pictures from Visualizers, the picture detail level, how the picture will get displayed in the application window and for EYE-12 / SCB-12 devices it's also possible to configure the "Trigger" functionality.
Especially the picture capture settings are important and most used by users of the application. The best settings for good performance for a specific user application is often a resolution / quality versus frame rate issue, especially in Continuous mode. Higher resolution / no compression means lower frame rate due to the higher amount of data which has to be transferred over the connection link which has a limited bandwidth of appr. 480 Mbps (USB 2.0) or appr. 100 Mbps (Ethernet / LAN). Compressed picture transfer with the native Visualizer resolution normally provides the best results for most applications.
To recall the default settings for this dialog tab, click "Reset settings". The other tabs of the "Preferences" dialog box are not affected.
The settings in this group box are only used by the "Still Image" capture function.
You can change the resolution of captured pictures from the connected Visualizer. Possible resolutions depend on the connected Visualizer model.
When checking the box, the captured pictures will be transferred as JPEG compressed pictures. You can adjust the picture quality by moving the "Picture quality" slider to the desired position (four quality levels are available).
A lower picture quality will result in a higher compression level of the picture which will reduce the amount of data to be transferred over the connection link. This will automatically increase the frame rate but the picture quality will be decreased.
The "Continuous single picture transfer" mode is available for all Visualizers which are connected over USB or Ethernet / LAN. For certain Visualizers connected over Ethernet / LAN also the "UDP multicast stream transfer" is available. note

The UDP multicast stream transfer settings are only available for Visualizers connected over Ethernet / LAN which do support this transfer method
In order for the multicast stream to work properly, the firewall and network settings have to be adjusted to allow UDP data transfer through the ports mentioned in the important notice on below the "Frame Rate" slider. Ask your network administrator for more details.
If the connected Visualizer supports this transfer mode it's the most suitable way to capture pictures form the Visualizer. The best setting for "Capture Resolution" depends on your needs. A higher capture resolution will result in a lower frame rate. The used bandwidth of your network can be defined with the "Frame Rate" slider. It also depends on the selected capture resolution. note

Tells the Visualizer how much bandwidth it should use for sending out the UDP multicast stream.
Please note: A higher frame rate results in higher network traffic. note
Changing this setting will change the sharpness / contrast of the picture of the Visualizer. This setting does not only affect the pictures captured over USB or Ethernet / LAN but also the DVI / VGA outputs of the Visualizer.
This setting controls the way a captured picture is displayed in the main window of the application. There are three different modes available:
Keep aspect ratio
You can resize the application window but if you release the mouse button the application will resize your selected window size to maintain the original aspect ratio of the displayed picture.
Fit to window
You can resize the application window in any direction and if you release the mouse button the displayed picture will get stretched to fit in the new window.
1:1
You can not resize the application window because the size of the window is dictated by the selected "Capture Resolution". The size of the window is adjusted to the same resolution as the selected "Capture Resolution".
To prevent cropped pictures, the computer screen resolution should be higher as the selected "Capture Resolution".
With activated trigger mode, the application will capture only those pictures from the Visualizer which were taken in response to a trigger event. The trigger function can be used for automated capturing.
For more information about the trigger function, please read the user manual of your Visualizer.
