WolfVision VZ-17 - Handbuch (Seite 9)

PRESET FUNCTION
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 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)
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).
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 videorecorders with component input
by simultaneously pressing the
following keys: IMAGE (#17), IRIS dark
(#19) and IRIS bright (#19).
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" (page 5).
