Introduction
Short introduction about WolfVision, Visualizers in general and respective applications:
•
Since 1990 WolfVision has been known as the "Technology Leader" in the Visualizer
market. The company that sets the standards when it comes to product quality, innovation
and ease of use. Completely focused on Visualizers, WolfVision offers a wide range of
solutions to meet customer's requirements, applications and budgets.
•
A WolfVision Visualizer is a special Live-Camera System which is designed to pick up
objects on and outside the working surface, using perfect lighting and depth in focus. All
types of objects (like photos, books, brochures, transparencies, slides or 3-dimensional
objects) can be picked-up very quickly and easily. This eliminates the need of producing
OHP-transparencies or slides, because a user can display all original objects. The image
produced by a WolfVision Visualizer can be displayed on TV-monitors or projected onto a
large screen using a video projector or data projector.
•
A Visualizer is the perfect presentation tool and can be used in various applications:
- meeting and conference rooms
- for training and education
- within court rooms
- as an enhancement to Videoconferencing systems
- for medical applications
- documentation and multimedia applications

Benefits of a Ceiling
Visualizer
Explanation of Advantage of a Ceiling
Visualizer
The basic idea behind the Ceiling Visualizer is to keep the speaker's table or lectern free, so that
nothing disturbs the view between the speaker and audience and objects can easily be moved
around the whole table.
In situations like this pastry cook training, it would
be impossible to place everything the audience is
supposed to see on a working surface of a
"Desktop Visualizer". A Ceiling Visualizer is the
ideal solution for such applications.
WolfVision's Ceiling Visualizers can be mounted to the ceiling like a projector. The design fits
perfectly to modern data projectors. Furthermore, the Ceiling Visualizers can also be integrated into
a suspended ceiling.
The Visualizers come with their own ceiling mounts. The height of the ceiling mount is only 40mm
(1.6"). To suspend the Visualizer from the ceiling, any standard ceiling mount for projectors can be
used. The flexible fixings will fit with almost any brand.
The connectors are on the top side of the unit. Accessing the cable connectors and the lamp
exchange cover is very easy, as the unit can be opened with just one pull. The automatic height
adjustment mode allows easy installation and also offers the possibility to expand the optical zoom
range with a height adjustable table or ceiling mount.

Easy to use
Explain how to operate the Visualizer
For a smooth presentation, it is very important that a Visualizer is extremely easy to use. Less
experienced users only need to push the ZOOM keys on the remote control.
When the unit is turned on, the focus automatically adjusts to the working plate 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 high depth of focus of the Visualizer, the focus rarely needs to be adjusted. Only very
high objects require a focus adjustment. To activate the One-push Autofocus, press both FOCUS
keys simultaneously.
One-push Autofocus
Everything else is adjusted automatically by the VZ-C12²/VZ-C32

A key feature of WolfVision's Ceiling Visualizer series is the Synchronized Lightfield. This popular
feature is a special patent of WolfVision and can only be found on WolfVision's Visualizers.
A lightfield, the size of the pick-up area of the built-in camera, is projected onto the working surface.
The illuminated part of the working surface is always identical to the pick-up area of the camera.
When zooming in and out, the size of this lightfield changes accordingly.
This allows very easy positioning of objects.

Special Surface for
Transparencies
The Ceiling Visualizers from WolfVision have got a special illumination system which makes it
impossible for the Visualizer's light to be reflected back into the camera. Thus the whole working
plate is always 100% reflection free.
Optional Lightbox for
X-Rays
The Wolfvision Ceiling Visualizers have a special crystalline white working plate 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".
For x-rays or (oversized) slides, external lightboxes are available in different sizes.

State of the Art
Picture Quality
Place the test chart onto working surface
and zoom in until the markings are clearly
outlined
Screenshot / Argumentation or Story
The key elements of the exceptional picture quality are:
•
WolfVision's Progressive Scan lens (the image is extremely sharp, even in the corners
of the picture)
•
WolfVision's Progressive Scan camera (Resolution and color reproduction are
outstanding.)
•
WolfVision's Intelligent Electronics
The VZ-C12² features a sensational 1-CCD camera with 1280 x 960 pixels at 30 frames per
second. This is native SXGA- resolution with an aspect ratio of 4:3. The camera also outputs
native 720p HD (High Definition) with 1280 x 720 pixels and an aspect ratio of 16:9. Using a
display device with 1280 x 960 (or more) pixels, 820 lines resolution are visible on your screen.
The VZ-C32 with its built-in 3-CCD XGA camera tops it all. It features an outstanding 3-CCD
camera with 3 x 1024 x 768 pixels at 30 frames per second. The 3-CCD camera offers
sharpness and color precision, which can not be achieved with a 1-CCD XGA or SXGA
camera (as a 1-CCD camera needs a part of the pixels for the color information). As a result, the
higher resolution is even visible on an XGA-projector. Using a display device with 1280 x 960 (or
more) pixels, 1000 lines resolution are visible on your screen.
Important: The difference in resolution between a 1-CCD and a 3-CCD camera can be
demonstrated best by using the lines on the test chart or by using small structures like the fine
details of small characters (e.g. like on the test chart). Samples of fabrics or text with Asian
characters (e.g. like the Chinese WolfVision brochures) are also very useful to demonstrate this
difference.

WolfVision Visualizers are renowned for their perfect color reproduction. The outstanding color
precision even meets the high requirements of the sRGB standard.
But only a 3-CCD camera can show 100% precise colors! The 1-CCD Visualizer comes close to the
real colors, but no 1-CCD camera can show all colors 100% precisely.
Important: To get the best picture quality, the projector or monitor should also be set to sRGB!

Extremely High
Depth of Focus

Demonstrate sharpness from top to

WolfVision uses professional telezoom lenses for the Ceiling Visualizer. This results in a very high
depth of focus.
High depth of focus is very important for working with larger 3-dimensional objects. Even at high
magnification, they are always sharp from top to bottom.
Due to the high depth of focus, using the manual focus keys or the one-push autofocus is hardly
necessary, as the focus virtually never needs adjustment.

What to do...
Screenshot / Argumentation or Story
The Ceiling Visualizers VZ-C12² and VZ-C32 have zoom lenses with an outstanding 16x optical
zoom factor. In combination with the 4x digital zoom, the total zoom range is 64 times.
This allows installation in rooms with differing heights, as the Ceiling Visualizers can zoom in very
close and also pick up very large objects.
A difference to standard Visualizers is that the size of the smallest and largest picture the units can
pick up is not fixed. Instead, it depends on how high above the table the Ceiling Visualizer is
mounted.
Calculation Program
A very comfortable method to calculate the exact positioning and the possible image sizes of the
Ceiling Visualizer is a dedicated calculation program on WolfVision's homepage:

Frames per second
Point to different areas of the test chart
and then make some finger movements
Screenshot / Argumentation or Story
Motion used to be the weakness of Progressive Scan cameras. Until recently, they could only pick
up 15 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 the zoom or iris. WolfVision's Progressive Scan Visualizers could always pick up at least
20 pictures per second, which is very important to show motion in good quality.
WolfVision has improved the technical standards for Progressive Scan cameras even more. All
current WolfVision Visualizer models can now pick up 30 pictures (frames) per second. There is
almost no difference in the smoothness of motion, when compared to PAL/NTSC video cameras.
However, the resolution is much higher!

With the VZ-C12²/VZ-C32 a user has the opportunity to store 9 images and recall them by just
pressing one of the numerical keys on the infrared remote control. 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-C12²/VZ-C32 is equipped with a battery backup, so pictures remain in the memory for 1-4
weeks even when the power is disconnected.

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.
Camera pick-up area:
Nearly all pixels of the camera are used to pick up the
letter
Place the demo page horizontally onto the
working surface and zoom out until the
whole page is visible again
Now press the IMAGE TURN key (return

been demonstrated)
Close up
of monitor
WolfVision's "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.
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.

the other outputs (DVI, RGB) can be set to output a "freeze" image.
This can be used for a "Live Picture to Freeze Picture Comparison" on two monitors or screens with
just one Visualizer. While one monitor or screen displays a "freeze" image for comparison, another
monitor or screen can be used for the presentation of the live image from the Visualizer.

Firmware Updates
All projectors, monitors or plasma displays on the market can display at least one of these
standards. If new standards come up in the future, WolfVision will be there with Firmware Updates!
Firmware Updates:
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 cost! Downloading firmware
updates from the internet and up-loading them onto the Visualizer is very easy. On the VZ-C12²/VZC32 the user can choose 3 different connections between Visualizer and computer for updating the
firmware: Serial (RS232), USB or Ethernet (LAN).
WolfVision's engineers are constantly working on new improvements and features to keep your
units up to date with the technology of tomorrow!

A computer can be connected to the RGB input (15-pin D-Sub/VGA-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 RGB and DVI output. The VZ-C12²/VZ-C32 has a built-in Digital Scaler which
converts the RGB signal from the external input for all outputs. The advantage of using the Ext/Int
switch is that only one RGB- or DVI-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. When the VZ-9plus is in stand-by mode the external signal is looped through
automatically. Once the Visualizer is turned on the live image will be displayed.

The USB output of the Visualizer can be used to transfer images from a Visualizer to a computer
and save them in JPG, TIF or BMP format. This way the Visualizers can be used as a 3-D
scanner for a computer.
WolfVision Visualizers are equipped with a fast USB 2.0 port. This allows for uploading images onto
a PC in a fraction of a second. Connecting slower computers with the older USB 1.1 standard is
also no problem. It still takes only a small fraction of the time a desktop scanner requires to scan an
image.

USB-Software available for Apple Macintosh) and is fully Twain compatible. This is important when
using the Visualizer in connection with popular graphic programs such as Photoshop, or for
connecting them to Interactive Whiteboards (Smart Boards).
The fast USB 2.0 port can also output live motion. The WolfVision Connectivity-Software can store
AVI-files and includes a video capture driver. You can view and save the live image from the
Visualizer on your computer with almost every modern video editing software.

The Visualizer is equipped with an Ethernet (LAN) port (10/100 Mbps). It is IP addressable and can
be integrated into a computer network and controlled from any computer in the network. It can even
be controlled over the internet, if it is assigned an official (WAN) IP-address.
The network/LAN-port has become a central feature of all high-end Visualizers from WolfVision in
recent years. Many new network features have been developed and most of them can also be
added to older units via Firmware Updates.
New LAN features are for example: Smart updates of all Visualizers which are connected to
network, remote maintenance (E-Mail Notification, Status Page) and Quality Optimized
Image Transfer via LAN.
