WolfVision VZ-17 - Manual (Page 10)

AUTOIRIS / MANUAL IRIS
(all Visualizers)
WolfVision Visualizers are equipped with autoiris. That means that the brightness of the camera image adjusts
automatically. Using the IRIS keys (#24) the autoiris function is switched off. In this mode the Iris can be adjusted
manually.
When using the ZOOM keys (#13) the autoiris 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 menu (#23) - see help menu (#25).
PRESET FUNCTION
(all Visualizers)
RESET FUNCTION / POWER-ON PRESET
(all Visualizers)
WolfVision Visualizers offer the possibility of programming three presets for the functions: Zoom, Focus, Iris,
Light, Image, Text, Macro and Mirror position*. They can be recalled by pressing one of the three PRESET keys
(#14) on the control panel or the remote control.
This function is very useful for example if a user requires one preset for papers on the working surface, one
for working with slides (bottom light) and one for an object placed in front of the unit. During his presentation
the user just has to press one of the PRESET keys key when he changes from one object to the other.
For programming a preset just adjust every function as required and then keep one of the PRESET keys
pressed for more than 4 seconds. The on-screen menu tells you when the preset is stored.
When switching on the unit the "Power-on Preset" is activated (=Top light on, Zoom at 210 x 148mm, Focus on
the working surface level, Mirror center). This function can be switched off in the units menu (#23) if required -
see help menu (#25).
This "Power-on Preset" can also be recalled during operation of the unit by pressing the RESET key (#20)

VIDEO RECORDING
(VZ-17 and VZ-37 only)
For video recording simply connect the Composite video output (#32)
or the Y/C output (#37) of the Visualizer to the according input of your
video recorder. Please note that the Y/C output offers the better
picture quality than the Composite video output. Connect a control
monitor to the output of the video recorder. The RGBS output (#40)
of the VZ-37 can be switched to YUV for professional video-
recorders with component input by simultaneously pressing the
following keys: IMAGE (#17), IRIS dark (#19) and IRIS bright (#19).
CONNECTING A COMPUTER OR VIDEO CONFERENCING SYSTEM
(all Visualizers)
A Visualizer can be used as document- and object-camera for video
conferencing systems. Furthermore it can be used as a 3-D scanner for
computers in order to digitize Visualizer images for image processing etc.
The computer has to be equipped with a frame grabber card or another
video INPUT device.
In order to archive the best picture quality please read the chapter
"Choosing the right video output" for VZ-37 and VZ-17 (page 5)
or "RGBS OUTPUTS" for VZ-47 (page 6).
* You can select in the unit's on-screen menu if the mirror position should
be stored in a preset or not (see page 14). Default is: YES.
