WolfVision VZ-C32 3 User Manual - Handbuch (Seite 10)

Please note that the Visualizer has an optical 16x zoom. The digital 4x zoom increases the overall zoom
range to a 64x zoom. However, please be aware that when the digital zoom is used, the resolution of the
picture is not as high as before.
The default setting displays a message on-screen when you are in the digital zoom mode.
Still images in the memory can also be digitally zoomed.
The behavior of the Visualizer in the digital zoom mode can be changed in the on-screen menu (see page
16).
Digital Zoom
When the Visualizer is turned on the focus automatically adjusts to the working surface level. As a result it is
not necessary to readjust the focus, if you are only working with flat material (text, photos etc.).
Due to the Visualizer's extreme depth of focus, the focus rarely needs to be adjusted.
Only very high objects require a focus adjustment.
To activate the One-Push Auto focus, press the AF key (#28).
Please note that objects with a very low contrast (like blank sheet of paper) are difficult to focus.
Focusing / One-Push Autofocus
WolfVision Visualizers are equipped with an auto iris. This means that the brightness of the camera image
adjusts automatically. Using the IRIS keys (#38) the auto iris function is switched off. In this mode the Iris
can be adjusted manually.
When using the ZOOM keys (#31) the auto iris function is switched on again.
Before the iris closes completely, the Visualizer automatically dims the light.
The standard auto iris level can be set brighter or darker in the unit's on-screen menu - see page 16 and on-
screen help.
Auto Iris / Manual Iris
The Visualizer offers the possibility to store the current settings as a Preset and recall them by just pressing
the respective PRESET key (#25) on the remote control.
(# )
For storing a reset adjust y function as required and then PRESET key
for 2 seconds . An on-screen message inform you when the Preset is stored.
Additionally up to three different Height Adjustment settings can be assigned to the presets in the on-screen
menu.
As mentioned above, when presets are stored all current settings such as zoom, focus, iris etc. are also
stored. Contrary to this, a user also has the opportunity to assign specific functions such as "NEGATIVE",
"NEGATIVE/BLUE", "BLACK/WHITE", "FREEZE", "LIGHT" etc. to a PRESET key in the on-screen menu
of the Visualizer (see page 16).
By pressing the FREEZE key 35 for 2 seconds, preset 1 will be recalled.

Text Mode
For improving the readability of text, sketches or x-rays, the text mode can be activated by pressing the
assigned PRESET key
.
This mode enhances the contrast of the picture. Please note that the colors are now darker than usual. To
switch off the text enhancement mode, press the
again. When the text
enhancement mode is in use, the message "TEXT" is displayed.
This should remind the user to switch off the text mode when it is no longer required. It should also prevent
users trying to correct dark colors by opening the iris, resulting in a poorly adjusted picture.
