How The Visualizer Works

a) light projector b) camera c) image path d) light path e) mirror light

(motorized) f) mirror camera g) pickup area / synchronized lightfield

A light projector (a) inside the unit projects a lightfield (g) the same size as the pick-up

area of 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 (#15) and plug it in

2. If you would like to use a control monitor, connect it to the PREVIEW RGB output (#23)

3. Connect a large viewing monitor or a projector to one of

the outputs of the Visualizer

For choosing the right output mode please see page 12!

4. Turn the main power switch (#12) on the unit to "I".

MEMORY

HELP

POWER

The power indication LED on the unit is illuminated red to indicate that power is supplied.

5. Press the POWER key (#41) on the remote control

The Visualizer now runs the “power-on preset” .

Power-on preset: The automatic setting of zooming to an middle zoom position (pick-up size depends on mounting height of the Visualizer), focus on the working surface level and the auto iris are activated. As soon as the Power Indication LED is green and stays illuminated, you can start working with the Visualizer. The behavior of the unit as soon as power is supplied or after the POWER key has been pressed can be changed in the unit's on-screen menu (see page 15).

The Unit Is Switched On The First Time

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

Installation

Please read first the Installation Manual before fixing the assembly to the room ceiling. 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 in the installation manual 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 from the ceiling.

Distance (refer to calculation program)

Speaker

Before deinstallation the unit please read first the Installation Manual!

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 pick-up size would be too large and the light output too low.

www.wolfvision.com/wolf/indexdistance.html

Synchronized Lightfield

If the top light of the Visualizer is used (default) a synchronized lightfield 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 light of the Visualizer by pressing the LIGHT key (#33) and work with room light.

Working Surface / Light Box

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 using the top light for transparencies due to better color reproduction and

because the synchronized lightfield still shows the pickup-area of the built-in camera.

In the following cases, the usage of an optional light box is recommended:

- If the transparency is very dark such as x-rays

Lightbox (optional)

- If the transparency is very wavy and causes reflections

- If the room light causes reflections on transparencies

When an optional light box is in use, the light of the Visualizer should be switched off. This has the disadvantage that the synchronized

lightfield of the top light no longer marks the pick-up area of the built-in camera.

Shooting Area 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 enlargement required with the ZOOM keys (#27).

3. When the image is out of focus, adjust the

Synchronized l ghtfieldi

sharpness with the FOCUS keys (#31).

Focusing / One-Push Autofocus

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

FOCUS

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.

To activate the One-Push Auto focus, press both FOCUS keys (#31) simultaneously.

Please note that objects with a very low contrast (like a blank paper) are difficult to focus.

Digital Zoom

Please note that the Visualizer has an optical 16x zoom. The digital 4x zoom increases the overall zoom range to a 64x zoom. However please be aware that when the digital zoom is used, the resolution of the picture is not as high as before. The default setting displays a message on-screen when you are in the digital zoom mode. Still pictures in the memory can also be digitally zoomed.

You can change the behavior of the Visualizer in the digital zoom mode in the on-screen menu (see page 15).

Auto Iirs / Manual Iris

IRIS

WolfVision Visualizers are equipped with an auto iris. This means that the brightness of the camera image adjusts automatically. Using the IRIS keys (#32) the auto iris function is switched off. In this mode the Iris can be adjusted manually. When using the ZOOM keys (#27) 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 15 and on-screen help.

Preset Function

PRESETS

2 3

The Visualizer offers the possibility to store the current settings as a Preset and recall them by just pressing the respective PRESET key (#29) on the remote control.

For storing a reset adjust y function as required and then PRESET key for 2 seconds . An on-screen message inform you

s on the remote control or more will

p : an press any one of the

when the Preset is stored.

Additionally up to three different Height Adjustment settings can be assigned to the presets in the on-screen menu.

As mentioned above, when presets are stored all current settings such as zoom, focus, iris etc. are also stored. Contrary to this, a user also has the opportunity to assign only specific functions such as "NEGATIVE", "NEGATIVE/BLUE", "BLACK/WHITE", "FREEZE" etc. to a PRESET key in the on-screen menu of the Visualizer (see page 15).

Freeze

The current image can be frozen by pressing the programmed PRESET key 29 . The behavior of the freeze function can be changed in the on-screen menu (see page 15).

(# )

Image Memory for 9 images

You can store 9 images and recall them by just pressing one of the numerical keys (#39) on the infrared remote control:

Storing an image: Press one of the MEMORY keys (#39) for 2 seconds or more Recalling an image: Press one of the MEMORY keys (#39)

quickly

Split image of 9 picture memory

By pressing the All key (#36) a split image with all 9 pictures of the memory can be displayed. When pressing the ALL key (#36) 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 all 9 memory locations are full. The Visualizer is equipped with a memory backup battery. If the power has been interrupted any pictures in the memory will be stored for up to 4 weeks.

The functional settings of memory erasing can be changed in the on-screen menu.

Image Turn Mode (for higher resolution)

Working surface:

Normal mode:

Only 50% of the

pixels are used to

pick up the document

Image turn mode: 90% of the pixels

are used to pick

up the document

Output picture:

Picking up a complete vertical (portrait) document or A4 page has always been a critical issue for a Visualizer because the

was

image 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.

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

zoom in on it completely, so that approx. 90% of the pixels of the built-in camera are used to pick up the document, then press the IMAGE TURN key (#30). The Visualizer turns the picture electronically 90 and outputs correctly with a much higher resolution than in normal mode. The left and right margins will be black.

Text Enhancement

For improving the readability of text, sketches or x-rays, the text mode can be activated by pressing the TEXT key (#34). This mode enhances the contrast of the picture. Please note that the colors are now darker than usual. To switch off the text enhancement mode, press the TEXT key again. When the text enhancement mode is in use, the message "TEXT" is displayed on the output and the TEXT key on the control panel is illuminated red.

This should remind the user to switch off the text mode when it is no longer required. It should also prevent users trying to correct dark colors by opening the iris, resulting in a poorly adjusted picture.

TEXT

White Balance Adjustment

IMPORTANT

LIGHT

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.

the white balance is continuously adjusted automatically.

This means that

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 (#33) 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):

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 for 2 seconds.

Lightbox with transparencies: Turn off the light of the Visualizer with the LIGHT key 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 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 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 15). 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.

Choosing the Correct Output Mode

The DVI and RGB outputs (#16, #18, #22 and #23) can output signals in following formats:

- VGA (4:3 - 640x480 pixels) at 60Hz

- SVGA (4:3 - 800x600 pixels) at 60Hz, 75Hz or 85Hz

- XGA (4:3 - 1024x768 pixels) at 60Hz, 75Hz or 85Hz

- SXGA- (4:3 - 1280x960 pixels) at 60Hz or 85Hz

- SXGA ( - 1280x1024 pixels) at 60Hz or 75Hz

- SXGA+ (4:3 - 1400x1050 pixels) at 60Hz or 75Hz

- UXGA (4:3 - 1600x1200 pixels) at 60Hz

- XGA 16:9 (special format for non-HDTV capable 16:9-Plasma displays) at 60Hz

- WXGA/60 (16:9 Widescreen - 1360x768 pixels) at 60Hz

- WSXGA+/60 (16:10 Widescreen - 1680x1050 pixels) at 60Hz

- 720p (16:9 Widescreen HD/HDTV - 1280x720 pixels) at 50Hz or 60 Hz

- 1080p (16:9 Widescreen HD/HDTV - 1920x1080 pixels) at 50Hz or 60Hz

The "Auto resolution" function is activated by default. In this mode the Visualizer continuously checks which devices are connected to the RGB (#16, #18 and #23) and DVI output (#22) and automatically sets the optimal output mode for each connected device separately.

connected units or the cables* are not "Plug and Play" compatible. If the Visualizer can not detect the resolution of the connected device, the output is set to the default of XGA/60Hz on VZ-C32 and SXGA-/60Hz on VZ-C12².

(*Cables with plug and play compatibility must have a 15-pin plug on both ends with all pins connected, pin 9 is not used).

If you can not use the "Auto resolution" function, you can select the output mode manually in the on-screen menu of the Visualizer (see page 15).

In order to achieve the best picture quality you must set the outputs of the Visualizer to match the native resolution of your display unit (e.g. LCD or DLP projector or monitor). Important: What matters is the native resolution of the projector or monitor, not the maximum resolution that it can display (in compressed mode). The native resolution is the actual number of pixels of the built-in LCD display or DLP chip of a projector or monitor. Most LCD or DLP projectors can also display higher resolutions than their native resolution, but only in compressed mode and with inferior picture quality.

Do NOT set the output of the Visualizer to a higher standard than the native resolution of your display unit!

If you output the Visualizer image on a CRT monitor or CRT projector, use an output mode with 75 or 85Hz, because 60Hz may show a slight image flickering. For LCD/DLP projectors or monitors and video conferencing units 60Hz is the best choice. If you are unsure what the best mode is, read the user manual of the connected units.

Do not set a higher refresh rate than your monitor or projector can display, otherwise the monitor or projector can be damaged! Follow the instructions in the user manual of the connected units.

Please note, if 4:3 and 16:9 or 16:10 resolutions are used simultaneously, the 4:3 display shows black bars on top and bottom. This is necessary to ensure that all displays show the same image content.

Please note that the Visualizer can not check the possible resolution, if the

External Infrared (IR) Sensor

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 (#26) and position the IR-sensor somewhere on the ceiling (or in the room) where the users normally point the remote control at.

IMPORTANT

External Input / Scaler - EXT/INT

A computer can be connected to the EXTERN IN port (#20) of the Visualizer. By pressing the EXT/INT key (#35) you can switch between the Visualizer image and the image of the external input to be displayed to the audience. The extern mode can also be used for only one output. The behavior can be changed in the on-screen menu (see page 15). The Visualizer has a built-in A/D-converter in order to digitize the analog RGB signal from the computer and output it on all outputs in the selected signal format (allowed input signals: from VGA to SXGA/75Hz). With the built-in scaler, computer signals can be converted to the PAL/NTSC video standard (VZ-C32 only).

Ethernet / LAN -Port 10BASE-T/100Base-TX

The LAN connection (#25) can be used for controlling the Visualizer over a computer network. Image transfers, firmware updates, displaying status information and e-mail notifications are possible.

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

d i b : /FirefoxSupporte nternet rowsers are Internet Explorer, Netscape Navigator and Mozilla .

By default, DHCP is activated to receive all settings automatically. Image transfer resolution: still image: 1024x768 (or 512x384), live image: 160x120 Please check the separate ETHERNET / LAN description on our internet homepage at:

www.wolfvision.com/support (or on the supplied CD-Rom).

USB-Port

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 works under Windows 98, ME, 2000, XP and 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 USB 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.

The USB output (#24) 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 also be used as scanners for 3-dimensional objects. WolfVision Visualizers are equipped with a fast USB 2.0 port. This allows uploading images onto a PC in a fraction of a second.
