WolfVision | VZ-8plus | VZ-8plus / VZ-8light

Unique folding system / Set up in seconds
WolfVision's portable Visualizers can be set up in
seconds. A gentle tug lifts the arm and light into
working position, then turn the camera head to the
desired viewing angle.
Just as easily, it folds back into its compact size with
just one pull on the center ring, to be neatly stored
during or after a presentation.
Easy to use - Only 5 buttons on the unit
It is very important for a smooth presentation that a
Visualizer is extremely easy to use. A speaker does
not want to deal with a lot of confusing and
unnecessary functions during his presentation.
That is why there are only 5 buttons on the unit itself.
Anyone can work with it without instructions.
Easy to carry
The Visualizer alone weighs only 4.5kg (10lbs). Together with its
carrying case and power pack it is still only 7.3kg (16lbs).
WolfVision's portable Visualizers come in a high quality carrying
case, with pockets for all the needed accessories.
The soft case has an expandable side pocket for a small LCDprojector or notebook.
Special light system
No blinding the audience or the speaker
The light of WolfVision's portable Visualizers is focused directly onto the working surface.
Due to the special lamp housing, neither the audience nor the speaker will be blinded in a
darkened room.
Minimum stray light
WolfVision Visualizers are perfect for large screen projection with a data projector. There is
almost no disturbing stray light from the unit to the projection screen.
Light swing (illumination in front of the unit)
The light of the portable Visualizers can be turned around horizontally at an angle of up to
250 degrees. Thus, objects in front of the unit can be illuminated as good as items on the
working surface.
The camera head can
be rotated 130 degrees.
Recordings in front of the unit
When objects are too big to be placed on the working surface or
need to be shown from the side (like glasses of liquids etc.), the
camera head and the light of the portable Visualizers can be
turned to accommodate them.
In this way a Visualizer can be used like a video camera on a
tripod, for recording people, large graphics, pictures or charts in a
lens drawer
For capturing objects in a larger distance to the
unit, the close-up lens can be removed with just
one pull. It can not get lost, because it remains
attached to the unit.
Continuous Autofocus
The continuously working autofocus recognizes all
objects very quickly and precisely. As a result, a
presenter never needs to worry about focusing. For
special objects a manual focus is also available.
State of the Art Picture Quality
"The VZ-8plus, has a lot of great and unique features, but the outstanding picture quality
puts everything into the shade." - a statement we heard very often since the VZ-8plus
was released.
Now the VZ-8light - a "light version" of the VZ-8plus - is also available. It has the same
outstanding picture quality, but reduced features. (All features available only on
VZ-8plus, but not on VZ-8light, are marked with * in this brochure.)
The key elements of the exceptional picture quality are:
- WolfVision's Progressive Scan lens (A special joint venture development between
WolfVision and a leading lens manufacturer. The first lens especially designed for a
Progressive Scan camera with a real optical 12 times zoom! The image is extremely
sharp, even in the corners of the picture. The continuous autofocus works very well)
- WolfVision's Progressive Scan camera (Resolution, color reproduction and digital
zoom are outstanding.)
- WolfVision's Intelligent Electronics (Allowing for firmware upgrades, which is a great
feature to keep your unit up to date with the latest developments)
"Progressive Scan" with High Resolution
Until recently all Visualizers were equipped with PAL or
NTSC video cameras.
Modern data projectors provide the ability to display
higher resolution images using its "data" input instead of
its "video" input. This is where "Progressive scan"
cameras come in. They output a "data" signal with more
resolution than PAL/NTSC "video" could provide.
Especially the vertical resolution is no longer limited to
400 lines from top to bottom (PAL standard) or 350 lines
(NTSC standard).
VZ-8plus and VZ-8light output a native XGA signal on
RGBHV (D-Sub) outputs.
The VZ-8plus can also switch the output mode to SXGA or
SVGA mode (at 75 or 60Hz) and offers a digital DVI output.
Plus it can also output the original Progressive Scan signal
converted into PAL or NTSC video (switchable).
Live-Image (20 pictures per second)
20 pictures per second (like WolfVision's VZ-8plus/VZ8-light):
The motion can easily be followed
7.5 or 15 pictures per second (like other manufacturer's units):
Pictures are output a couple of times. Motion is hard to follow.
"Motion" used to be the weakness of Progressive
Scan cameras. Until recently they could only pick
up 15, 7.5 or less pictures per second. A low
number of pictures per second often resulted in a
disturbing strobe effect on the screen, whenever
something was moved in the picture or when
adjusting zoom or iris.
It is very important for a professional presentation
that motion can be shown in good quality and
without any image disturbance. WolfVision uses
newly developed Progressive Scan CCDs which
can pick up 20 pictures per second for the VZ8plus/VZ-8light. As a result, motion looks almost
as good as with PAL/NTSC video cameras. But
the resolution is much higher!
Firmware updates via Internet
WolfVision's Visualizers are the only units on the market that offer an
upgradeable firmware.
This allows for new features and technical improvements to be added at no
Downloading firmware updates from the internet and up-loading them onto the
Visualizer through the serial RS232 input is very easy.
WolfVision's engineers are constantly working on new improvements and
features to keep your units up to date with the technology of tomorrow!
"Image turn" mode for higher resolution *
Picking up a complete vertical (portrait) letter or A4
page has always been a critical issue for a
Visualizer, because the image is always picked up in
a horizontal (landscape) format. As a result, only
50% of the camera pixels could be used to pick up
the vertical (portrait) document.
Normal mode:
Camera pickup area:
Only 50% of the
pixels of the camera
are used to pick
up the letter.
WolfVision's unique "Image Turn" mode solves this
problem. The user places the document on the
working surface horizontally and zooms in on it
completely. In doing so, approximately 90% of the
camera's effective pixels are used to pick up the
document. WolfVision's state of the art electronics
turn the image at an angle of 90 degrees and output
it in a vertical format with 40% higher resolution.
The margins left and right are blacked out.
Close up

Image turn mode:
Camera pickup area:
Nearly all pixels
of the camera
are used to pick
up the letter.
In this mode the resolution of a complete vertical
(portrait) document is much better. Even 8-point
characters are readable now.
Another advantage of the image turn mode is that
very long vertical pages (like US legal format) can
be picked up completely.

9 Picture memory *
With the VZ-8plus a user has the
opportunity to store 9 images and recall
them by just pressing one of the
numerical keys on the infrared remote
By pressing the "All" key, a split image
with all 9 pictures of the memory can be
displayed, enabling easy selection.
The 9 pictures in the memory can also be
downloaded to a PC via USB.
The VZ-8plus is equipped with a battery
backup, so pictures remain in the
memory for 1-4 weeks even when the
power is disconnected.
The VZ-8light offers a 1 image freeze
function, instead of the 9 picture memory.
Text Enhancer* / Negative / Negative-blue
The VZ-8plus offers many possibilities to improve the readability of text.
By pressing the "Text Enhancer" button, the outstanding contrast of the picture is
improved even more. The colors are just a little bit darker than before.
with Text Enhancer
Sometimes dark text on a bright background may be easier to read if the Visualizer is
switched to "negative" or "negative/blue".
For special applications (like analysing x-rays) the image can also be switched to black
and white.
Computer input (loop-through)
just one
A computer can be connected to the RGBHV input (15-pin DSub-plug) of the Visualizer. With the Ext/Int switch a user can
switch between the Visualizer image and computer image to be
output by the Visualizer's RGBHV output (15-pin D-Sub-plug).
Thus, only one XGA-cable to the display unit (projector, monitor,
video conferencing system etc.) is required and no separate
remote control has to be used for switching between the two
image sources.
USB output / 3-D scanning in less than 2 seconds
The USB output of the VZ-8plus and VZ-8light can be used to transfer still
pictures from a Visualizer to a computer and save them in JPG, TIF or
BMP format. In this way the Visualizers can be used as a 3-D scanner for
a computer. No additional hardware is required for this.
It only takes 2 seconds until images are loaded onto the computer. This is
much faster than with any desktop scanner. In addition, the Visualizer can
also be controlled through the USB software.
The software works under Windows 98, ME, 2000 and XP and is fully
Twain compatible. This is important for using the Visualizer in connection
with popular graphic programs like Photoshop or for connecting them to
Smart Boards.
The USB-connection is perfect for transferring still pictures. Live images can also be transferred onto a computer very
easily using a standard PAL/NTSC video digitalisation card (grabber card).
Optimized for video conferencing
WolfVision's camera electronics produce a very strong and stable
picture, which is very important when a Visualizer is used as a document
camera for videoconferencing systems. The even lighting, smooth auto
iris and perfect focus are very important features, enabling video
conferencing systems to digitize and transfer the picture from a WolfVision
Visualizer much faster than pictures from other document cameras.
Furthermore there is no blinding stray light from a WolfVision Visualizer,
which could disturb the auto iris of the room camera.
Of course these features are equally important for live image
presentations with a data projector and for other Visualizer applications.
Special surface for transparencies
All WolfVision Visualizers have a special crystalline white working surface for perfect
reproduction of transparencies. The quality of a transparency on this surface is even
better than with a bottom light, because there is more contrast and the colors are not
"washed out".
The whole working surface has the same even color, providing a perfect background for
transparencies and other objects.
For x-rays or oversized slides external lightboxes are available.
24x zoom (12x optical and 2x digital)
A large optical zoom range is one of the most
important features of a Visualizer. It is absolutely
necessary that objects in every size can be
picked up in full resolution.
Whole working surface
370 x 276mm (14.6" x 10.9")
24 time zoom
24 times smaller
WolfVision's optical 12 times zoom offers the
possibility to pick up objects as large as an open
book (370 x 276mm / 14.6" x 10.9") and as small
as a stamp (33 x 25mm / 1.3" x 1") in full size to fill
the screen.
For enlarging even smaller objects down to 17 x
13mm (0.7" x 0.5") the Visualizers also offer a 2x
digital zoom. This allows for enlarging objects like
a very small coin.
In theory 2 times digital zoom would mean double
the size and half the resolution, but WolfVision's
new digital zoom is much better than this.
Due to the large range optical zoom, it is not
necessary to have more than 2 times digital zoom.
