Focusing / Autofocus
Please note that objects with very low contrast (like blank sheets of paper) are difficult to focus. If the
autofocus does not work just move the object slightly.
For special applications the autofocus can also be switched off using the on/off switch (#23). The autofocus
is also switched off when the manual FOCUS keys (#22) are used.
Optical Zoom / Digital Zoom
Please note that the Visualizer has an optical 14x zoom. The digital 2x zoom increases the overall zoom
range to a 28x zoom. The smallest pickup size on the working surface without digital zoom is 29 x 22mm
(1.1" x 0.9"). When you zoom in further the digital zoom is automatically activated and the smallest pickup
size is 15 x 11mm (0.6" x 0.4"). However please be aware that when the digital zoom is used, the resolution
of the picture is not as good as before. The default setting displays a message on-screen when you are in
the digital zoom mode.
Image ratio is affecting the size of pick-up are, it depends on selected output resolution.
You can change the behavior of the Visualizer in the digital zoom mode in the on-screen menu (see
page 10).

menu. When picking up areas with bright spots, Back Light Compensation can be switched on in the unit's
on-screen menu - see page 10 and on-screen help.
