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 eld 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 benet 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.
5. 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 ne-tune the focus if you are
not satised with the results.
You may still need to use the arrow marks to ne-tune the focus depend-
ing on the live image on your screen. “>” means moving from wide to tele end; and “<” tele to wide.
