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.
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 fine-tune
the focus if you are not satisfied with the results. You may still need to use the arrow marks to
fine-tune the focus depending on the live image on your screen. “>” means moving from wide to
tele end; and “<” tele to wide.
