WolfVision's High Quality Standards |

|
Mechanical quality is a basic requirement for all WolfVision products. WolfVision units are solid and can hardly be damaged. They are built to last a very long lifetime. |
(Metal housing) |
| If you want to check out the difference in mechanical stability and reliability between a WolfVision Visualizer and any other document camera on the market, just "touch" the units. You will immediately "feel" the difference. |

|
WolfVision Visualizers have always been famous for their outstanding picture quality, which is due to a perfect mixture of high end components and remarkable know-how.
Perfect picture quality means high resolution throughout the whole picture (including the edges), lifelike colors, high frame rate, fast and precise auto focus, smooth zooming, an overall distortion free picture, even lighting without reflections or hot spots and much more.
WolfVision's high priority on perfect picture quality can be seen on the wohle product line - from the entry level to the top of the line Visualizers.
The picture quality of a Visualizer or camera can only be as good as its weakest component. The following 5 basic elements are responsible for perfect picture quality, as found on all WolfVision units: |

Keep
your Table Free / Hide the Visualizer in or on the Ceiling |
|
 |
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.
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. |
Other advantages
compared to "Desktop" Visualizers:
- Visualizer
can be completely hidden in a suspended ceiling
- No cables from the table to the ceiling
- Objects can be even larger and higher
- Fix installed unit can hardly be stolen |
|
Designed
like a Projector / Supplied Ceiling Mount |
|
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.
WolfVision's
Ceiling Visualzers come with their own ceiling mounts.
The height of the ceiling mount is only 40mm (1.6").
To suspend
the Visualizer from the ceiling (in order to get bigger enlargements),
any standard ceiling mount for projectors can be used. The Ceiling
Visualizers have flexible fixings which will fit with almost
any brand. |
|
The Ceiling
Visualizers VZ-C32 and VZ-C12² come
in a new housing - small and elegant. 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 (see picture above).
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
Positioning (with Synchronized Lightfield) |
|
 |
A key feature
of WolfVision's Professional and Ceiling Visualizer series is
the Synchronized Lightfield. This popular feature is a special
patent of WolfVision and thus 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. There
is no need to look at a monitor. Just place the object in the
illuminated portion of the working surface! |
|
|
 |
This is the key new feature of the latest Ceiling Visualizer models VZ-C32 and VZ-C12².
New lenses
with very large zoom range allow for the installation of Ceiling
Visualizers in rooms with differing heights. The units can pick
up larger objects and zoom in closer, than the previous Ceiling
Visualizer models.

The picture quality
of the 1-CCD Visualizer VZ-C12² is very good, but the 3-CCD
XGA camera of the VZ-C32 tops it all. The built-in camera shows a 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.
The high end scaler of the Visualizers can scale the picture at the image source. As a result the picture quality is not only perfect in native resolution, but also in all scaled signal formats. |
 |
WolfVision offers free test charts which reveal the great
difference in resolution and color reproduction between WolfVision's new
3-CCD Visualizers and any other high resolution Visualizer. The range of WolfVision's
test charts goes up to 1600 lines.

Both
units output the picture on RGB- (15-pin D-Sub and BNC connectors) and DVI outputs. The Auto Resolution function
recognizes the connected projector or monitor and automatically
selects the perfect output mode. |
|
|

|
The high end scaler can scale the picture at the image source. As a result the picture quality is not only perfect in the native resolution, but also in all scaled signal formats.
The native
signal output of the Visualizers has an aspect ratio of 4:3. The native 4:3
image can also be output in the following additional 16:9 and
16:10 widescreen formats: 720p HD (High Definition), 1080p HD (both at 50 or 60 Hz), WXGA and WSXGA+.
All widescreen
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! |
|
30
Pictures per Second (Real Time Live Image) |
|
|
"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 for showing 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. But the resolution is much
higher! |
|
Firmware
Updates through RS232, USB or Ethernet (LAN) |
|

|
WolfVision's
Visualizers are the only units on the market that offer upgradeable
firmware. This
allows new features and technical improvements to be added
at no cost!
Downloading
firmware updates from the internet and uploading them onto a
Visualizer can be done in 2-3 minutes, with just 4 mouse clicks, using the latest version of WolfVision's Connectivity Software. |
The user can choose from 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!

|
The professional telezoom lenses of the WolfVision's Professional and Ceiling Visualizers feature 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. No other unit on the market comes close to
the extremely high depth of focus of WolfVision's Professional and Ceiling Visualizers.
The
Visualizers are equipped with a One-Push-Autofocus. However
due to the great depth of focus, it is rarely necessary
to adjust the focus. |
|
|

Illumination
with shadows: |


|
|
As
the camera and the light projector are situated side by side within
the Visualizer and follow the same path, shadows are
almost completely eliminated.During a
presentation, it is often necessary to write something on a document
on the working surface or to point to a certain detail with a
finger or a pencil.
The
Visualizers are perfectly suited for this, as there is practically
no shadow covering up important details. |
|
Illumination
of Hollow Objects / No Light Adjustments |
|
Illuminated
on inside: |
Not
illuminated on inside: |
|
|
Due to the
special light system of the Visualizer, every part of
the recorded picture is always perfectly illuminated. Hollow objects
or complex 3-D objects are always completely illuminated -
even on the inside.
As a result,
there is never a need for adjustment of the light. |
|
|

|
The illustrations on the left show that with the special illumination
system of WolfVision's Ceiling Visualizer series, it is impossible
for the Visualizer's light to be reflected back into the camera.
Thus the
whole working surface is always 100% reflection free.
No light
adjustment is necessary in order to avoid disturbing reflections
on glossy material (photos, transparencies, etc.) |
|
USB
2.0 Port / Twain / Video Capture / AVI |
|

The USB port 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, Visualizers can be used as scanners for 3-dimensional objects.
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. |

WolfVision's
USB Software (Connectivity Software) works under Windows 2000, XP and Vista
and is fully Twain compatible. This is important when using Visualizers in connection with popular graphic programs such as Photoshop, or for connecting them to Interactive Whiteboards (Smart Boards). A USB Software for Apple Macintosh is also available. Click here for a detailed description of the WolfVision Connectivity Software
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 in almost every modern video editing software. |
|
Ethernet
(LAN) Port / Advanced LAN features |


|
The Visualizer is
equipped with an Ethernet (LAN) port (10/100 Mbps). It is IP-addressable,
so that it 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 key 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. |
Computer
Input (Internal/External Switch) |
A computer
can be connected to the RGB input (15-pin D-Sub-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 output (15-pin D-Sub-plug) and DVI output.
Therefore, only one RGB or DVI cable is required to be attached to the display unit (projector, monitor, video conferencing system etc.) and no separate remote control has to be used for switching between the two image sources.
The Visualizer has a built-in digital image scaler which can process
the signal from the external input and output it in the same
mode as the Visualizer image (For example: If the Visualizer is set to
output an XGA image to the projector and the computer outputs an SVGA
signal, the scaler of the Visualizer converts the SVGA image of the computer
to XGA. As a result the projector does not readjust the input mode when
switching between the Visualizer and computer image)
In addition the
scaler also allows the image from the external input to be output on
the DVI output and even on the PAL/NTSC video output. Thus the
VZ-C32 can also be used as a computer-video image converter.
X-large
Lightbox LB-38 can be Used |

Check
out the accessories page, for information about lightboxes. |
Transparencies can be picked up in perfect quality on the supplied crystalline
white working plate of the Ceiling Visualizers. For x-rays and slides, an external lightbox is required.
A big
advantage of the Ceiling Visualizers in the medical field,
is that it can also pick up the largest x-rays. For
this purpose, WolfVision offers the very large optional
Lightbox LB-38. The size of the lit area is 430 x 359mm
(16.9" x 14.1"). The unit has a very elegant appearance
and is very thin (only 14mm / 0.6"). |
Perfect
for Video Conferencing |
|
The big advantage
of a Ceiling Visualizer in a video conferencing application is
that it is completely invisible to the audience. As you
can see in the illustration on the left, documents can be picked
up on the table, directly in front of the speaker.
This is much
more convenient than with a "desktop visualizer", which
always has to be placed at an acceptable distance to the speaker.
Otherwise it could disturb the visual contact between camera/monitor
and speaker. |
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. The Visualizer also supplies the proper signal for modern widescreen videoconferencing systems. |
|
"Image
Turn" Mode for Higher Resolution |
Picking up a complete vertical (portrait) letter or A4 sized page has always been a critical issue for a Visualizer because the image has always been 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.
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 to a 90 degree angle 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. The 1-CCD Visualizer VZ-C12² can show 8-point characters and the 3-CCD Visualizer VZ-C32
can even show 6-point characters. Another advantage
of the image turn mode is that very long vertical pages (like US legal format) can be picked up completely.
|
Live
to Freeze Comparison |
|

|
The
Preview output of the Visualizers always outputs the live image
of the Visualizer camera, while all other outputs (DVI, RGB etc.)
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 that can be used for comparison, another monitor or screen can be used for presenting the live image from the Visualizer. |

Split image of
9 picture memory |
The 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 and they remain in the memory even when the power is disconnected. |

WolfVision Visualizers offer many possibilities to improve the readability of
text.With the "Text Enhancer" function, the outstanding contrast of the picture is improved even more with colors only slightly darker than before.
Dark text on a bright background can sometimes be easier to read if the Visualizer is switched to "Negative" or "Negative/Blue".
For special applications (like analyzing x-rays), the image can also be switched to Black and White. |
