the built-in camera via the mirror (e) onto the
working surface. The image is recorded by the
camera (b) using the same path via the mirror (f).

The lenses of the light projector (a) and the
camera (b) are synchronized. Thus the size of the
light field on the working surface changes when the
user changes the zoom range of the camera.

This scanning and illumination system is a
worldwide patent from WolfVision.

BASIC PREPARATIONS

1. Connect the power cable to the unit (#28) and plug it in.

2. If you would like to use a control monitor, connect it to the
following outputs:
Computer monitors:Preview RGB output (#32)
Video monitors:Y/C (S-Video) output (#36) or
Composite Video output (#37).

4. Turn the main power switch (#26) on the unit to "I"
(The status-LED indicates that power is supplied).

5. Press the POWER-key (#23) on the remote control. The Visualizer now runs the “power-on preset”
(automatic focusing of an DIN A5 format on the working surface, pick-up size depends on mounting
height of the Visualizer) during which the green LED light (#26) is flashing. As soon as the green
LED light stays illuminated, you can start working with the Visualizer. (The behaviour of the unit
once that power is supplied to the unit or after the POWER-key is pressed can be changed in the
unit’s on-screen menu (see page 9).

INSTALLATION

When the unit is turned on for the first time, the Height Adjustment starts automatically. The Ceiling
Visualizer is pre-set to a distance of 2 m (78.76"). In most installations the installation height will be
different to this, so the following adjustments must be performed:

1. Adjustment of camera and light focus

2. Alignment of lightfield and camera field

NOTE: This is a one time setup, which must only be performed again if the distance between the
Visualizer and table is changed! - more details in the installation manual

3

INSTALLATION

The size of the smallest and largest image that the unit can pick up is not fixed. It depends on the
distance between the working surface and the bottom of the Visualizer. The tables below show the
relationship between mounting height and pick-up sizes:

In extremely high rooms the smallest image the unit can pick-up may not be small enough. In such

cases a standard ceiling mount or projector-lift can be used to suspend the Ceiling Visualizer further

Distance (refer to calculation program)

Speaker

Use the calculation program on WolfVision's internet homepage to calculate the exact position and
image sizes :

The distance is measured from
the bottom of the Ceiling
Visualizer to the working
surface. These figures may vary
a little in reality, because the
position of the focus influences
the size. Masking of the monitor
or projector should also be taken
into consideration (i.e. some
units cut off the edges of the
picture). Theoretically larger
distances than 4000mm (approx.
160") are possible, but the pick­up size would be too large and
the light output too low.

WORKING ON THE WORKING SURFACE

1. Place your subject material on the working surface.
A synchronized lightfield on the working surface marks
the pick-up area of the built-in camera!
Just place your subject material in the illuminated area.

2. Select the required enlargement with the ZOOM-keys (#13).

3. Adjust the sharpness with the FOCUS-keys (#17)
if necessary.

SYNCHRONIZED LIGHTFIELD

If the top light of the Visualizer is used (normal working condition) a synchronized lightfield

LIGHT

18

always marks the pick-up area of the built-in camera on the working surface. The alignment of this
lightfield is made for working on the working surface.

Because of the oblique mounting of the camera and the light projector of the Visualizer, the lightfield
shifts to the right when the distance between the Visualizer and the scanned object is decreased (when
capturing high objects).
This means that the lightfield no longer exactly shows the recorded area. In this case switch off the
Visualizers top light with the LIGHT-key (#18) and work with room light.

FOCUSING

When the Visualizer is turned on the focus automatically adjusts to the

17

+

17

working surface 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 great depth in focus of the Visualizer, the focus rarely needs to be adjusted.
Only very high objects require a focus adjustment.

Pressing both FOCUS-keys (#19) simultaneously, activates a One-Push Auto focus.

(Please note that this is a new function, introduced in Mai 2005 with firmware Version 1.13a.
Units with older firmware perform an Auto focus for flat objects with this key combination.)

AUTO IRIS / MANUAL IRIS

WolfVision Visualizers are equipped with an auto iris. This means that the

20

brightness of the camera image adjusts automatically. Using the IRIS-keys (#20) the auto iris function is
switched off. In this mode the Iris can be adjusted manually. When using the ZOOM-keys (#13) the auto
iris 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 on-screen menu

- see page 9 and on-screen help.

5

DIGITAL ZOOM

When zooming in, the zoom stops at the smallest image the OPTICAL zoom can pick up. If you press
the ZOOM IN-key again after the stop, the unit activates its digital zoom extension and you can zoom
in further. The unit has a 4x digital zoom.

The behaviour of the digital zoom can be changed in the on-screen menu - see page 9.
Please note that the resolution in the digital zoom area is lower than in the optical zoom area!

BOTTOM LIGHT / LIGHTBOX (optional)

An external lightbox (bottom light) is recommended for dark transparent
material such as x-rays or for very small transparent material such as slides.

When a lightbox is used, the top light of the Visualizer should be switched off with the LIGHT-key (#18).
Using a bottom light has the disadvantage that the Synchronized Lightfield of the top light no longer
marks the pick-up area of the built-in camera.

When switching off the top light, the Ceiling Visualizer also switches the white balance adjustment from
"one-push" white balance to "auto-tracking" white balance. This compensates the varying color
temperatures of different light sources - see page 7 and 9.

The recommended lightbox for the Ceiling Visualizer is the WolfVision Lightbox LB-38.

18

WORKING WITH TRANSPARENCIES

The working surface of the Visualizer (#9) has a special crystalline white
color, which is especially designed for perfect reproduction of
transparencies.

Even if you own an optional light box, it is recommended to use the top
light for transparencies, because of the better color reproduction and the
advantage that the Synchronized Lightfield still shows the pickup-area of
the built-in camera.

However, in these situations it is recommended to use a bottom light:

- If the transparency is very dark

Lightbox

- If the transparency is very wavy and causes reflections

(optional)

- If the room light causes reflections on a transparency

TEXT ENHANCEMENT

For improving the readability of text, sketches and x-rays
Press the TEXT-key (#16). This mode enhances the contrast of the picture. Please note that in this
mode the colors are darker than usual. To switch off the text enhancement mode press the TEXT-key
again.

IMAGE TURN MODE (for higher resolution)

Working surface:

A

Just place your document (or other vertical object)º on the working surface horizontally and zoom in on it

completely, so that about 90% of the pixels of the built-in camera are used to pick up the document.
Then press the IMAGE TURN-key (#15). The Visualizer turns the picture electronically 90 and outputs
it the right way up with a much higher resolution than in normal mode. The left and right margins are
black.

Normal mode:

Only 50% of the

pixels are used to

pick up the document

Image turn mode:

WHITE BALANCE ADJUSTMENT

Correct white balance adjustment is important for an exact color reproduction!

Each time the lighting condition changes, the Visualizer's camera must readjust its white balance, in
order to optimize the color reproduction. The lighting condition (color temperature) changes, for
example, if changing between Visualizer's light and an external lightbox (bottom light) or if room light is
turning on or off.

The standard settings of the Visualizer are the following:
When the Visualizer's light is switched on: fixed white balance.
When the Visualizer's light is switched off: "auto-tracking" white balance.

balance is continuously adjusted automatically.
For an exact white balance, at least 10% of the recorded image should be white (measurement area is

the center of the image).
For a precise fixed white balance adjustment use the "One Push" white balance. This can be done by
pressing the LIGHT-key (#18) for 2 seconds. When the white balance is stored an on-screen message
appears. Setting a "One Push" white balance switches off the "Auto Tracking" mode (When the unit is
switched off and on again the "Auto Tracking" mode will be reactivated).

Normally there is no need for a manual white balance adjustment. However, if the colors on the screen
still appear to be wrong, the white balance can be adjusted manually (one-push):

Output picture:

A

A

Picking up a complete vertical (portrait) document or
A4 page has always been a critical issue for a
Visualizer, because the image is always picked up in
a horizontal (landscape) format.

The camera could only use 50% of its pixels to pick
up a vertical (portrait) page. WolfVision's Image turn

mode solves this problem.

IMPORTANT

This means that the white

Hints to perform an One-Push white balance:
Top light: Zoom in on a white object (i.e. a sheet of paper) until there is only white on the screen,

press the LIGHT-key (#18) for 2 seconds.

Lightbox with transparencies: Turn off the light of the Visualizer with the LIGHT-key (#18) and

switch on the lightbox. Remove everything from the light box and zoom to the smallest picture size
until there is only white on the screen, press the LIGHT-key (#18) for 2 seconds.

Lightbox with x-rays: Turn off the light of the Visualizer and switch on the lightbox. Place an x-ray on

the light box and zoom out until the whole x-ray is picked up, press the LIGHT-key (#18) for 2
seconds.

Please note: False colors can also be due to wrong color settings of your projector or monitor. It is
recommended to adjust the white balance of the Visualizer at first and if the results are still not
satisfactory, monitor or projector should be checked.

For specialists: The Visualizer can be switched between "Auto Tracking", "One Push" and "Manual" white balance mode in the on-screen
menu (see page 9). If you work with negative transparencies and a light box, use a blank (black in the image) part of the negative film for
white balance adjustment! The "one Push" white balance will be separately adjusted and stored for top light and external light.

PRESET FUNCTION

WolfVision Visualizers offer the possibility of programming three presets
for the functions: Zoom, Focus, Iris, Light, Image, Text, Freeze, White Balance,
Positive/Negative. They can be recalled by pressing one of the three PRESET-keys (#14) on 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 a high object. During his presentation the user just
has to press one of the PRESET-keys when he changes from one object to the other.

Quickly pressing: Recalling a preset
More than 2 seconds: Saving a new preset

For programming a preset just adjust every function as required and then keep one of the PRESET­keys pressed for more than 2 seconds. The on-screen menu tells you when the preset is stored.

Black/White and

FREEZE

The current image can be frozen by pressing the programmed PRESET-key 4 .
The FREEZE-key (PRESET) also works as image memory key if pressed for 2 seconds (see below).
The behavior of the freeze function can be changed in the on-screen menu (see page 9).

9-IMAGE MEMORY

Split image of 9 picture memory

When pressing the ALL-key (#25) for 4 seconds, a menu appears on the screen asking if you would
like to erase all stored pictures (black picture) or if you would like to fill the memory with “snapshots”.
When choosing “snapshot” the Visualizer stores a new image every second until the 9 memory
locations are full. The Ceiling Visualizer is equipped with a memory backup battery. It stores the
pictures in the memory when the power supply is disconnected for 1-4 weeks.
Images can also be stored by pressing the FREEZE-key (PRESET) for 2 seconds. The image will be
stored in the next available memory (1-9). If the memory is full, an on-screen message will appear.

The functional settings of the memory feature can be changed in the on-screen menu (see page 9).

You can store 9 images and recall them by just pressing
one of the numerical keys (#31) on the infrared remote control:

Storing an image: Press one of the MEMORY-keys (#31)
for more than 2 seconds
Recalling an image: Press one of the MEMORY-keys (#31)
quickly

By pressing the All-key (#25) a split image with all 9 pictures
of the memory can be displayed.

Ethernet / LAN

The LAN connection (10BASE-T/100BASE-TX) can be used for controlling the Ceiling Visualizer over a
computer network, image transfers and firmware updates.

The following protocols are supported: TCP/IP, ICMP and ARP.

Supported Browsers are Internet Explorer, Netscape Navigator and Mozilla.
Standard settings (changeable): IP-address, Subnet-mask, Gateway, DHCP-Server
Image Transfer Resolution: Still Image: 1024x768 (or 512x384), Live Image: 160x120

USB-PORT

The USB 2.0 output of the Ceiling Visualizer can be
used to capture and transfer Visualizer images onto a

HI-SPEED

CERTIFIED

TM

computer.
In this way the Visualizer can be used as a 3-D
scanner for your computer. Just connect the USB port
(#30) of the Visualizer and the USB port of your
computer, using the supplied USB cable. The software
is twain compatible. The USB 2.0 output is also
compatible with USB 1.1 (less speed with USB 1.1).

The WolfVision USB-software can be found on the supplied CD-ROM. Please check our Internet
homepage at: www.wolfvision.com/support if an update of this software is available as a free­download.
The software works under Windows 98/ME/2000/XP and MAC OS10 (or later).

EXTERNAL INPUT / SCALER

A computer can be connected to the External RGB input (#34) of the Visualizer.

EXT/INT

24

By pressing the EXT/INT-key (#24), you can switch between the Visualizer image and the image of the
external input to be displayed to the audience.
The external mode can also be used for only one output. The behavior can be changed in the on­screen menu (see below). The Ceiling Visualizer has a built-in scaler (A/D-converter) in order to digitize
the analog RGB signal from the computer and output it on all outputs in the selected format (allowed
signals: from VGA to SXGA/75Hz). As the built-in scaler allows the image from the external input to be
output on the PAL/NTSC video outputs, the Ceiling Visualizer can also be used as a computer to video
image converter.

External Infrared (IR) Sensor

IMPORTANT

In some rooms the 3 built-in infrared receivers of the Ceiling Visualizer may not be enough. In this case
connect the supplied external infrared receiver to the IR-sensor plug (#39) and position the IR-sensor
somewhere on the ceiling (or in the room) where the users normally point the remote control at.

ON-SCREEN MENU / ON-SCREEN HELP

For standard use of the WolfVision Visualizer it is not necessary to enter the on-screen
menu of the Visualizer and change settings. Inexperienced users should not make any
adjustments here.

To enter the on-screen menu press the MENU-key (#19) for one second. Settings of the Visualizer's
basic functions and the built-in camera can be made here using the 4 select keys (= the numerical keys

with red arrows on the remote control - #22).

Please note that some basic settings in the menu can only be changed if you set the menu item
"Format protect" to "OFF" first.

If more information on a function in the on-screen menu is required just set the cursor in the respective
line and press the HELP-key (Number 5 key #21, this key has a double function). A detailed description
of this function appears on the screen. If you want to reset the selected item to the default setting, just
press the HELP-key (Number 5 key #21) for 2 seconds!
The functions of the on-screen menu are not described in detail in this user manual as the help menu is
an integrated part of the Visualizer's software (firmware). The information you see on your screen
always belongs to the current Visualizer firmware.

SWITCHING TO NEGATIVE, NEGATIVE/BLUE and BLACK/WHITE

The output image of the Visualizers can be switched from positive to negative in the on-screen menu.
In addition, the background of a negative image can be switched to blue for better readability of text.
You can also switch between color and black/white in the on-screen menu.

TIP: If you often switch to negative, negative/blue or black/white images you can assign this function to
one of the Preset keys (see page 9) in the on-screen menu.

Changing the standard contrast (color) settings

If the picture or the colors on your screen appear to be too dark, you can lower the overall contrast of
the picture in the "Color settings" menu of the on-screen menu. The settings can be made separately
for the normal mode and the text-mode.

Auto Power Off

In the "Power control" settings in the on-screen menu you can select that the Visualizer will be
automatically switched off, if not used for a certain amount of time.

RESET OF ON-SCREEN MENU SETTINGS

All settings in the on-screen menu can be set back to the factory defaults. "Reset" is one item in the on­screen menu.
If you only want to reset a currently selected item to the default setting, press the Help key (Number 5
on the remote control #21) for 2 seconds!

FIRMWARE UPGRADES

The software (firmware) of your Visualizer (including the o ) can easily be upgraded to
