Infrared remote control

One of the unique features of WolfVision's portable Visualizers is that there are only 5 buttons on the unit. Therefore anyone can use it without instructions. For more experienced users there are some additional functions on the remote control:

#20 ZOOM

The Zoom keys are the most important keys on the IR-remote control. That is why they stand out colored. ZOOM keys are also on the camera head of the Visualizer.

#21 PRESETS (programmable settings)

For storing a preset press one of the PRESET keys for more than 2 seconds. For recalling a preset press the preset key

quickly. (Details see page 7)

#22 IMAGE TURN Mode

For picking up vertical (Portrait) pages with higher resolution (see page 8)

#23 Manual FOCUS

When the Focus keys are pressed the Visualizer switches off the autofocus function. The next time the zoom keys are pressed the autofocus is switched on again.

#24 Manual IRIS (brightness adjustment)

When the Iris keys are pressed, the Visualizer switches off the auto iris function. The next time the zoom keys are pressed the auto iris is switched on again.

For specialists: The overall iris level can be lowered in the on-screen menu (see page 9)

Page 5

Choosing the right output mode (SXGA/XGA/SVGA at 75 or 60Hz)

The RGBHV- and DVI-output (#13 and #12) can output signals in the following formats:

- SXGA (1280x1024 pixel) at 60Hz

- XGA (1024x768 pixel) at 75Hz (default setting when resetting the resolution)

- XGA (1024x768 pixel) at 60Hz (default setting if auto resolution does not work)

- SVGA (800x600 pixel) at 75Hz

- SVGA (800x600 pixel) at 60Hz

The default setting is that the "Auto resolution" function is activated. In this mode the Visualizer constantly checks which units are connected to RGBHV- (#13) and DVI-output (#12) and automatically sets the output to the mode that fits best for all connected units.

Please note that the Visualizer can not check the possible resolution, if the connected units or the cables* are not "Plug and Play" compatible. If the Visualizer can not detect the resolution of ALL units connected, the outputs are set to the default of XGA (1024x768) at 60 Hz. (*Cables with plug and play compatibility must have a 15-pin plug on both ends with all pins connected)

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 9) or with the following key combinations: For a lower mode simultaneously press both ZOOM keys on the camera head (#10) together with the number 8 (arrow-down) key (#29) on the remote control. For a higher mode press both ZOOM keys on the camera head (#10) together with the number 3 (arrowup) key (#29) on the remote control. In order to reset the output to the default setting (start point) of XGA (1024x768) at 75Hz, press both ZOOM keys on the camera head (#10) together with the number 5 key (middle of the number keys #31) on the remote control.

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 75Hz, 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 is the best mode read the user manual of the connected units.

PAL/NTSC video outputs

You can switch the Y/C (S-video) (#14) and Composite (#15) video outputs between the video standards PAL and NTSC in the units on-screen menu (see page 9). Switching can also be done by pressing both ZOOM keys on the camera head (#10) together with the Preset

1 (for PAL) or Preset 2 (for NTSC) (#21) key on the remote control.

Please note that the picture quality of both video outputs is NOT AS GOOD as the picture quality of the data outputs (#12 and #13). This is because of the limitations of the PAL/ NTSC video system and because of the fact that this is just a converted Progressive Scan signal and not an original video signal. The picture quality of the Y/C (S-video) (#14) output is still MUCH BETTER than the quality of the Composite (#15) video output. Please note that images from the EXTERNAL INPUT (#11) are not output at the Y/C (S-video) and Composite output!

Page 6

Autofocus:

When switching on the unit the autofocus is automatically switched on too. The correct focus is continuously adjusted. The green light beside the autofocus on/off switch (#9) shines if the autofocus is on.

Please note that objects with a very low contrast (like a blank sheet of paper) are difficult to focus. If the autofocus does not work just move the object slightly.

For special applications the autofocus can also be switched off using the on/off switch (#9). The autofocus is also switched off when the manual zoom keys of the remote control are used.

Manual focusing

You can use the focus-keys on the remote control for manual fokus. If the remote control is not available you can use this method:

1. Place an object at the level you wish to focus - The autofocus is focusing the object.

2. Switch off the autofocus with the on/off switch (#9) - The focus remains unchanged from now on.

WolfVision lightboxes (optional)

Connect the power cord to the light box connector (#19) on the back side of the Visualizer. The light switch (#6) of the Visualizer can now be used to switch between the light of the Visualizer and the light of the lightbox.

Other lightboxes:

In order to prevent reflections the light of the Visualizer always has to be switched off when working with lightboxes.

Digital Zoom

Please note that the VZ-8 has an optical 12x zoom, which is digitally increased to a 24x zoom. The smallest pickup size on the working surface without (!) digital zoom is 23 x 31mm

(0.9" x 1.2"). When you zoom in further the digital zoom is automatically activated and the smallest pickup size is 12 x 16mm (0.5" x 0.6"). However please be aware that when the digital zoom is used the resolution of the picture is not as good as before. The default setting is that a message appears on-screen when you are in the digital zoom mode.

You can change the behaviour of the Visualizer in the digital zoom mode in the on-screen menu (see page 9).

Shooting area on the working surface:

to infinity

Eliminating reflections

In order to eliminate reflections (on high gloss photographs etc.) just turn the light backwards slightly.

Please note that reflections can also be caused by the room light.

Shooting area outside of the working surface:

Turning the light backwards

In order to enable recordings with illumination outside of the working surface, the light of the Visualizer can be horizontally turned an angle of up to 250 degrees.

Close-up adaptor lens

For shooting an object outside the working surface, in a further distance to the unit, the close up lens (#7) has to be removed. In this case just pull the lens away from the main optic of the camera until it reaches the locked position. It is impossible to remove the lens completely from the unit, therefore it can not get lost. Before turning back the camera into the standard working position push the close up lens back in.

Page 7

White balance:

Correct white balance adjustment is important for true colors! The default white balance setting when the VZ-8 is shipped is "Auto Tracking". This means that the white balance is continuously adjusted. If the colors appear to be wrong try to However an "Auto Tracking" white balance can never be 100% correct.

For a more precise white balance adjustment use the "One Push" white balance. This can be done by completely zooming in a white paper on the working surface and pressing the LIGHT-key (#6) for 3 seconds. When the white balance is stored an on-screen message appears. Setting a "One Push" white balance switches off the "Auto Tracking" mode and the current white balance setting remains in the memory even when the unit is switched off. When the lighting conditions change (e.g. different room light or sunlight) the white balance should be readjusted!

For specialists: in the on-screen menu (see page 9) If you work with negative transparencies and an external light box, use a blank (dark) piece of the negative film for white balance adjustment!

The VZ-8 can be switched between "Auto Tracking", "One Push" and "Manual" white balance mode

move any object in the picture.

Slide Drawer

First make sure that you remove any object from the working surface (very important!). Then insert a slide in the slide drawer. The camera

camera head

automatically recognizes the slide and focuses on the slide.

In case the slide is out of focus:

- Make sure that the slide is firmly in place

- Make sure that the ZOOM is not in the maximum tele

slide

Text Enhancement

position (=smallest picture). Use the ZOOM-keys (#10 or #20)

IMPORTANT

For improving the readability of text, sketches or x-rays press the TEXT-key (#25). 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. While the Text Enhancement mode is on, the message "TEXT MODE" is constantly displayed in the picture. This should remind a user to switch off this mode when it is not needed anymore. The constant display of the word "TEXT MODE" could be switched off in the on-screen menu of the Visualizer (see page 9) however we do not recommend to do so. Because without this message users may tend to open the IRIS, instead of pressing the TEXT-key, if the picture appears to be too dark. This would cause a misadjusted picture.

Preset Function

The VZ-8 offers the possibility to store the current settings as a Preset and recall them by just pressing one of the three PRESET keys (#21) on the remote control. For storing 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, iris etc. are stored. Contrary to this, a user also has the opportunity to assign only specific functions such as "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).

Page 8

USB-PORT

The USB output of the VZ-8 can be used to transfer Visualizer images onto a computer. No additional computer hardware (like a grabber card) is required. In this way the Visualizer can be used as a 3-D scanner for your computer. Just connect the USB port (#16) of the Visualizer and the USB port of your computer, using the supplied USB cable.

A dedicated WolfVision USB-software can be found on the CD-ROM. Please check our Internet homepage at: www.wolfvision.com/wolf/techinfo.html if an update of this software is available as a free-download. The software works under Windows 98/ME/2000. Windows XP will also be supported. Windows 95 and NT will not work, because they do not support USB.

9-IMAGE MEMORY

You can store 9 images and recall them by just pressing one of the numerical keys (#29) on the infrared remote control:

Storing an image: Press one of the memory keys (#29) for more than 2 seconds Recalling an image: Press one of the memory keys (#29)

quickly

Split image of 9 picture memory

If you would like to fill all 9 memories quickly (e.g. with your company logo or a black image) just press the ALL key (#27) for 4 seconds. Then a new picture is stored every second until the memory is full.

By pressing the "All" key (#27) a split image with all 9 pictures of the memory can be displayed.

IMAGE TURN MODE (for higher resolution)

Working surface:

Just place your letter (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 letter. Then press the IMAGE TURN key (#22). The Visualizer turns the picture electronically 90 and outputs it the right way up with 40% 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 letter

Image turn mode: 90% of the pixels

are used to pick up the letter

Output picture:

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. So the camera could only use 50% of its pixels to pick up a vertical (portrait) page. WolfVision's new "Image turn" mode solves this problem.

Page 9

EXTERNAL INPUT

A Computer can be connected to the External RGBHV input (#11) of the Visualizer. With the Ext/Int switch (#26) a user can switch between the Visualizer and Computer image to be displayed to the audience.

The signal from the computer is just looped through the Visualizer and is not processed in any way. In order to avoid that your projector or monitor adjusts itself when switching, it is recommended that you set the output of the computer to the same signal format (SXGA, XGA or SVGA) and vertical frequency (75 or 60Hz) as the Visualizer. The default output settings of the Visualizer is: XGA (1024x768) at 75Hz.

DVI-output: Please note that the image from the External RGBHV input (#11) can only be displayed on the analog section of the DVI-output (#12) and not on the digital section of this output (see page10).

The following chapters are for experienced users only:

ON-SCREEN MENU / ON-SCREEN HELP

For standard use of the WolfVision Visualizer it is not necessary to go into the Visualizer's menu and change settings. Inexperienced users should not make any adjustments there.

To enter the on-screen menu press the MENU-key (#28) 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 - #30). Please note that some basic settings in the menu can only be changed you set the menu item "Format protect" to "OFF" first.

If you require more information on a function in the on-screen menu just set the cursor in the respective line and press the HELP key (#31, This is a double function of the Number 5 key). Than 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 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. The information you see on your screen always belongs to the current Visualizer software (firmware).

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 on-screen 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 both ZOOM-keys on the camera head (#10) and the Number 4 (back-arrow) key (#29) on the remote control. If you only want to reset the item that is currently selected to the default setting, press the Number 5 (#31) key for 2 seconds!

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 and white in the on-screen menu. TIP: If you switch often to negative, negative/blue or black/white images you can assign this function to one of the Preset keys (see page 7) in the on-screen menu.

Page 10

Auto Power off

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

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.
