User's Manual - 59
The methodology of using the Resize Buttons at the upper left corner of the streaming
window is the same as that on the home page.
Focus window:
By default, the optimal focus is found on a full view window. You may designate a custom window
within your current field of view to acquire the best focus out of it. However, you can not place a
focus window on a distant background, e.g., a hall way that stretches away for 3 meters or farther.
Doing so you will not benefit from the Focus window function.
■
Full view
: The focus tuning takes place by referring to the full view.
■
Custom
: You can create a focus window and drag it to a place of interest in your view window.
Note that it is recommended to use this function only when you have a solid object in your view
window that is showing a consistent color or texture. This function will not take effect if you set
the focus window on a distant background.
6. Wait for the scan to complete. After a short while, the clearest image obtained should
be displayed and the optimal focus range achieved. Use the arrow marks on the sides
to fine-tune the focus if you are not satisfied with the results.
You may still need to use the
arrow buttons to fine-tune the focus depending on the live image on your screen. “>” means mov
-
ing from wide to tele end; and “<” tele to wide.
7. Click on the
Enable iris
button to save the current configuration.
Please refer to page 128 for information about the
Snapshot Focus
feature. This feature
is enabled as a VADP package.
