HOW THE VISUALIZER WORKS

a) light projector b) camera c) light path d) image path e) base mirror f) top mirror g) pickup area / synchronized lightfield

BASIC PREPARATIONS

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 base mirror (e) and the top mirror (f) onto the working surface. The image is recorded by the camera (b) using the same path.

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.

1. Connect the power cable to the unit (#35) 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 (#39) Video monitors: Y/C (S-Video) output (#43) or Composite Video output (#44).

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

For choosing the right output please read page 11 and 12!

4. Turn the main power switch (#33, on the back of the unit) to "I". The red power indicator (#29) on the control panel indicates that power is supplied.

5. If the arm is folded down press the ARM-key (#27) on the control panel, then the arm comes up automatically.

6. Press the POWER-key (#28) on the control panel. The Visualizer now runs the "power-on preset" (=automatic focusing of an A5 format on the working surface) during which the green LED light (#29) 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 menu - see page 9 and on-screen help)

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

3. Use the MIRROR-keys (#12) on the control panel or the remote control to

change the vertical position of the pick-up area. The upper mirror can also be moved by hand! This does not cause any harm to the motor of this mirror!

DO NOT TOUCH THE MIRROR SURFACE, AS FINGERPRINTS

Synchronized lightfield

CAUSE BRIGHT AND HAZY SPOTS ON THE PICTURE ! ALWAYS KEEP THE MIRROR CLEAN ! - see page 13 CAUTION: SENSITIVE FRONT COATED MIRROR!

SYNCHRONIZED LIGHTFIELD

If the top light of the Visualizer is used (normal working condition) 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 left when the distance between the Visualizer and the scanned object is increased (when capturing images outside of the working surface). This means that the lightfield no longer exactly shows the recorded area. In this case switch off the Visualizer’s top light with the LIGHT-key (#21) and work with room light.

WORKING OUTSIDE THE WORKING SURFACE

For showing 3-dimensional objects with the WolfVision Visualizer, just place them on the working surface and adjust ZOOM and FOCUS (as mentioned). Due to a special WolfVision lens the object can be up to 25 cm (9.7") in height. If the object is to big for the working surface or if you want to show it from the side just place it behind or in front of the unit and tilt the top mirror by hand or using the MIRROR-keys (#12).

In this way it is also possible to make recordings of objects in the room or surrounding area, just like with a video camera.

to infinity

700mm (27.6")

Due to the great focal range it is possible to show details in every distance to the unit.

If you want to record people you should turn off the light with the LIGHT-key (#21), so that they are not blinded by the light.

FOCUSING

When the Visualizer is turned on the focus automatically adjusts to the 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.). Furthermore, due to the great depth of focus of the Visualizer it is rarely necessary to readjust the focus.

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 auto-iris. That means that the brightness of the camera image adjusts automatically. Using the IRIS-keys (#24) 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 menu

- see page 9 and on-screen help.

MACRO MODE / 4x DIGITAL ZOOM

In the fully extended position of the arm, the smallest pick-up area is 42 x 33mm (1.6" x 1.3").

When pressing the MACRO-key (#18) the length of the arm is automatically reduced, this allows greater enlargements. In the

macro mode the smallest pick-up area with full optical resolution is: 30 x 22mm (1.2" x 0.9"). When zooming in, the

zoom stops at this size.

If you press the ZOOM IN-key again after the stop, the unit activates its digital zoom extension. In this mode you can zoom into a picture as small as 8 x 6mm (0.3" x 0.2”).

Please note that the resolution in the digital zoom area is lower! The MACRO-key is illuminated in red color if the macro function is activated.

Please note that the macro mode has the following limitations:

- The depth of focus and the object height that can be focused is not as large as in the fully extended arm position.

- The largest pick-up size is only about 42 x 33 mm (1.6" x 1.3").

- When zooming the Synchronized Lightfield stays at a larger size and no longer marks the pick-up area of the built-in camera. The Laser Center Marker (see next chapter) is activated as a substitute.

If sufficient depth of focus and focusing high objects in the macro mode is more important than big enlargements, it is possible to switch the Visualizer from 12x zoom to 11x zoom in the Visualizer's menu (see page 9). The smallest pick-up size in the 11x macro mode is only 33 x 25mm (1.3" x 1"), but the depth of focus is larger than in the 12x macro mode.

BOTTOM LIGHT / LASER CENTER MARKER

The LIGHT-key (#21) can be used to switch between:

"Top light" (with Synchronized Lightfield) "Bottom light" with Laser Center Marker

Laser center marker

"Light off"

The bottom light should be used for dark transparent materials such as x- rays or for very small transparent material such as slides.

Using the 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. However as a substitute the Visualizer has a built-in Laser Center Marker, which marks the center of the pick-up area. This can also be used for positioning of objects (especially with big enlargements, like when picking up a slide).

The Laser Center Marker is only visible on the working surface and NOT on the picture the audience sees. For safety reasons the Laser Center Marker is automatically switched off when the top mirror is tilted to record outside of the working surface. If required the Laser Center Marker can also be switched off completely in the unit's menu (see page 9 and on-screen help menu).

Please note that for technical (optical) reasons the laser center marker can not show the exact middle center of the pickup area in every position of the arm. This is not a failure of the unit! However it is always very close to the center.

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 though the professional Visualizers have a built-in bottom light 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 the bottom light:

- If the transparency is very dark

- If the transparency is very wavy and causes reflections

- If the room light causes reflections on a transparency

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

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) one time. 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.

The IMAGE TURN-key (#15) can also be used to rotate the image 90, 180 and 270 degrees. Each time this key is pressed, the image rotates 90 degrees.

Output picture:

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.

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.

While the text mode is activated the TEXT-key on the control panel is illuminated red.

IMPORTANT

WHITE BALANCE ADJUSTMENT

Each time the lighting condition changes, the user should adjust the white balance of the Visualizer's camera, in order to optimize the color reproduction. The Visualizer's top- and bottom-light have the same color temperature so normally a new white balance adjustment is not necessary when changing from one light to the other, but if there is also room light or sun light shining on the working surface, the white balance should be adjusted.

Top light: First, zoom in on a white object (for example a white paper) until there is only white on the screen. Then press the WHITE-key (#22).

Bottom light: Turn on the bottom light with the LIGHT-key (#21). Remove everything from the working surface. Zoom to the smallest picture. Then press the WHITE-key (#22).

You can adjust the white balance either for the top or for the bottom light and it works well with both lights. When the white balance adjustment is finished successfully the message "WHITE OK" appears on the monitor after a few seconds. The new white balance is stored automatically and is preserved even if the power supply is interrupted.

PRESET FUNCTION

WolfVision Visualizers offer the possibility of programming three presets for the functions: Zoom, Focus, Iris, Light, Text, Macro, White Balance, Mirror position*, Positive/Negative and Black/White. They can be recalled by pressing one of the three PRESET-keys (#14) on the control panel or 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 an object placed in front of the unit. During his presentation the user just has to press one of the PRESET-keys when he changes from one object to

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

* You can select in the unit's on-screen menu if

the mirror position should be stored in a

preset or not (see page 9). Default is: YES.

For programming a preset just adjust every function as required and then keep one of the PRESET keys pressed for more than 2 seconds. The on-screen menu tells you when the preset is stored. When the presets are stored as mentioned above, all current settings like zoom-, focus- or mirrorposition are stored. Contrary to this, a user also has the opportunity to assign only specific functions such as "Freeze", "Iris open/close", "Negative", "Negative/Blue", "Black/White" etc. to a PRESET-key. This can be done in the on-screen menu of the Visualizer (see page 9).

FREEZE

The current image can be frozen by pressing the FREEZE-key 7 . The FREEZE-key is red illuminated if the freeze function is activated. The FREEZE-key also works as

image memory key if pressed for 2 seconds (see page 8). The behavior of the FREEZE-key can be changed in the on-screen menu (see page 9).

9-IMAGE MEMORY

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 (#30) a split image with all 9 pictures of the

Split image of 9 picture memory

memory can be displayed.

When pressing the ALL-key (#30) 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 Visualizer is equipped with a memory backup battery. It stores the pictures in the memory when the power supply is disconnected for up to 4 weeks. Images can also be stored by pressing the FREEZEkey (#17) 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).

USB-PORT

The USB 2.0 port of the Visualizer can be used to capture and transfer Visualizer images onto a computer.

HI-SPEED

CERTIFIED

In this way the Visualizer can be used as a scanner for 3-dimensional objects for your computer. Just connect the USB port (#37) of the Visualizer to the USB port of your computer, using the supplied USB cable. The software is fully Twain compatible. The USB 2.0 output of the Visualizer is fully USB 1.1 compatible (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). Windows 95 and NT will not work, because they do not support USB.

ETHERNET / LAN

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

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

Standard settings (changeable): IP-address and Subnet-mask from DHCP-Server Image Transfer Resolution: Still Image: 1024x768 (or 512x384), Live Image: 160x120

Please check the special ETHERNET/LAN manual on our homepage at: www.wolfvision.com/support.

EXTERNAL INPUT / SCALER

A Computer can be connected to the External RGB input (#41) of the Visualizer. By pressing the EXT/INT-key (#20), you can switch between the Visualizer image and the image of the external input to 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 9). The 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 Visualizer can also be used as a computer to video image converter.

:Supported Browsers are Internet Explorer, Netscape Navigator and Mozilla.

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 (#23) for one second. Settings of the Visualizer's basic functions and the built-in camera can be made here using the 4 select keys (#26, = the numerical

keys with red arrows on the remote control - #31).

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 (#25, or the Number 5 key #31, 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 (#25, or Number 5 key #31) 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 (#14) in the on-screen menu (see page 7).

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. In case you can not read the menu on a screen you can also set the unit back to the factory defaults by simultaneously pressing the EXT/INT-keys (#20) and the MENU-key (#23) on the unit.

If you only want to reset a currently selected item to the default setting, press the Help-key (#25, or Number 5-key on the remote control #31) for 2 seconds!

FIRMWARE UPGRADES

The software (firmware) of your Visualizer (including the o ) can easily be upgraded to the latest version. First download the latest firmware and WolfVision's firmware update utility program from Wolfvision's internet homepage at www.wolfvision.com/support.

Then connect the Visualizer to your computer and run the firmware update utility program. More details on the firmware updates can be found on WolfVision's internet homepage.

The firmware update can be done via USB, Ethernet (LAN) or RS232.

INFRARED REMOTE CONTROL

Please note that an infrared remote control can only be used up to a certain distance from the unit. Objects situated between the Visualizer and the infrared remote control, and weak batteries, interfere with the reception. If the Visualizer can only be controlled from a close distance, or if it cannot be controlled at all with the infrared remote control, you may have to change the batteries. Open the cover on the back of the remote control by hand and replace the two 1.5 V AA batteries with new ones.

Check the polarity of the batteries!

AUTOMATIC LAMP CHANGER

The Visualizer is fitted with an automatic lamp changer. If one lamp fails, there is no need to replace it immediately, as the automatic lamp changer automatically switches to the second (spare) lamp. When the unit changes lamps there is an on-screen message saying: "Changing lamp".

When switching on the unit the Visualizer checks if both lamps are working. If one lamp fails there will be an on screen message for a couple of seconds displaying "Lamp x blown". This prevents a user from forgetting to change a defective lamp.

If a lamp is not fully defective but worn out and as a result the light output is quite weak, you can switch manually to the second lamp by pressing the LIGHT-key (#21) for 2 seconds.

EXCHANGING LAMPS

1. Turn the unit off (#28) and disconnect the power cord!

2. Remove the bottom light (#9) by pulling the two spring catches (situated left and right of

Lamp exchange cover (#11)

the control panel) to the front and lift up the bottom light plate.

3. Remove the lamp exchange cover (#11) by turning anti-clockwise and lift it.

4. Change the lamp (or both lamps)

Before changing the lamp allow it to cool or use a cloth to avoid burning a finger! When pressing a new lamp into the socket use a cloth to prevent fingerprints on the lamp!

Only use 12 V/100 W halogen lamps (socket: GY 6,35), type: Osram HLX 64623, Ansi EVA, LIF M/28 NAED 54052. These are relatively inexpensive standard OHP lamps.

THERMOSTAT

If the unit gets too hot (improper ventilation or air extraction) a built in thermostat will switch off the light of the Visualizer. Verify that proper ventilation and air extraction is available and allow the unit to cool.
