Choosing the right output mode

The RGB- and DVI-output (#18 and #17) can output signals in the following formats:

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

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

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

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

- SXGA (4:3 - 1280x1024) at 60Hz, 75Hz or 85Hz

- SXGA+ (4:3 - 1360x1024) at 60Hz or 75Hz

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

- XGA 16:9 at 60Hz (special format for not HDTV-capable 16:9-Plasma displays)

- WXGA/60 (16:9 Widescreen - 1366x768 Pixel at 60Hz)

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

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

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

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

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

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 the connected device, the output is set to the default of XGA (1024x768)/60Hz.

(*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. Resolution and refresh rate can be adjusted separately for both outputs.

(the on-screen menu is visible on the built-in LCD monitor - see page 10).

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.

The "Auto resolution" function is activated by default. In this mode the Visualizer constantly checks which devices are connected to the RGB- (#18) and DVI-output (#17) and automatically sets the optimal output mode for each connected device separately.

Widescreen is supported since Firmware Version 1.20a (Older units may need a Firmware update for Widescreen support). Please note that WolfVision added widescreen support to the Visualizers in order to assure 100% compatibility with all display units on the market. However the native image ratio of the Visualizer camera is 4:3. Therefore 25% of the picture (4:3) is cut off when the Visualizer outputs in 16:9 or 16:10 widescreen format, while the resolution of the image stays the same.

Upscaling to HD/HDTV does not bring any improvement in resolution. However if you are using a display device with an aspect ratio of 16:9 or 16:10, the picture quality usually is better, when the Visualizer scales the image to the widescreen format, and not the display device. This is because the Visualizer scales the picture at the image source with high end electronics.

HDTV is developed for digital television. For compatibility, the image can be also output on the analogue RGB-output (#18) in HD/HDTV format. The DVI-output (#17) is HDMIcompatible (A DVI-HDMI adapter or a DVI-HDMI cable can be used).

Please note, if a 4:3 and a 16:9 or 16:10 display is used simultaneously, the 4:3 display shows black bars on top and bottom (the black bars are also visible on the built-in preview display). This is necessary to ensure that all displays show the same image content.

Display modes of monitors or projectors (Overview)

(for details please read the user manual of your display unit)

- "Aspect" keeps the original aspect ratio of the picture and will display black bars when

the not-native ratio of the display device is used.

- "Fill" always fills the screen of the display unit and will show a horizontally or vertically

stretched image on display units of the "wrong" format.

- "1:1" the display unit shows the image in the original number of pixels.

Parts which can not be displayed are cut off.

Special information for Widescreen Support

You can switch the Y/C (S-video) (#16) video output between the video standards PAL and NTSC in the units on-screen menu (see page 10). Switching can also be done by pressing both FOCUS keys on the camera head (#26) together with the Preset 1 (for PAL) or Preset 2 (for NTSC) (#32) key on the remote control.

Please note that the picture quality of the video output is NOT AS GOOD as the picture quality of the data outputs (#17 and #18). 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.

Digital Zoom

Please note that the VZ-9 has an optical 12x zoom. The digital 4x zoom increases the overall zoom range to a 48x zoom. The smallest pickup size on the working surface without (!) digital zoom is 23 x 31mm (0.91" x 1.22"). When you zoom in further the digital zoom is automatically activated and the smallest pickup size is ver 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. 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 10).

allows for horizontal pan shots when using the Visualizer as a camera to record outside of the working surface. It is also very useful when two people, sitting on the same table,

Connect the power cord of the light box to the light box connector (#22) on the back of the Visualizer. The LIGHT key (#23) of the Visualizer can now be used to switch between the light of the Visualizer and the light of the lightbox.

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

Shooting area on the working surface

Eliminating reflections

In order to eliminate reflections (on high gloss photographs etc.) just turn the light up-/down wards slightly.

Please note that reflections can also be caused by general room lighting conditions.

Close-up adaptor lens

For shooting an object outside of the working surface, the close up lens (#5) has to be removed. In this case just hinge the lens away from the camera head. It is impossible to remove the lens completely from the unit, therefore it can not get lost. When using the Visualizer again to record on the working surface, put the close up lens back to its original position.

Shooting area outside of the working surface

Turning the light upwards

In order to enable recordings with illumination outside of the working surface, the light of the Visualizer can be turned vertically.

Flexible Viewing Angle

In order to record at a lower viewing angle than the normal working position, just fold the arm of the VZ-9 as much as required.

Built-in LCD Monitor

The built-in LCD monitor makes positioning of objects very easy and it eliminates the need for an additional control monitor. This monitor can show different signals, like “external in”image, stored-image or life-image (selectable in the on-screen menu see page 10). The onscreen menu is also visible on this LCD monitor. The brightness of the LCD-monitor is adjustable in the on-screen menu.

Image Flip

By turning the camera head to record in front of the Visualizer, the image is automatically turned around 180 degrees (”image flip”). This feature is very useful for recording the face of the presenter or objects hanging on the wall behind the unit.

EXTERNAL INPUT

A computer can be connected to the External RGB input (#15) of the Visualizer. By pressing the Ext/Int switch (#29 or #37) 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 10). The VZ-9 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).

Preset Function

Text Enhancement

The VZ-9 offers the possibility to store the current settings as a Preset and recall them by just pressing one of the three PRESET keys (#32) 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. An on-screen message informs you, when the Preset is stored. When 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 10).

For improving the readability of text, sketches or x-rays press the TEXT-key (#37). 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 permanently displayed on the built-in LCD monitor.

This should remind the user to switch off the text mode when it is not needed anymore. It should also prevent that users try to correct dark colors by opening the iris. This would produce a misadjusted picture.

White balance

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

This means that the white balance is continuously adjusted automatically. For an exact white balance, 10% of the recorded image should be white (measurement area is in the center of the image). For a precise fixed white balance adjustment use the "One Push" white balance. This can be done by completely zooming in on a white sheet of paper on the working surface and pressing the LIGHT-key (#23) for 2 seconds. When the white balance is stored an onscreen message appears. Setting a "One Push" white balance switches off the "Auto Tracking" mode (When the unit is switched off and on again the

When the lighting conditions change (e.g. light box, sunlight or different

room light) the white balance should be readjusted!

For specialists:

If you work with negative transparencies and a light box, use a blank (black in the image) piece of the negative film for white balance adjustment! The “One Push” white balance will be separately adjusted and stored for top light, slide light field and external light box.

"Auto Tracking" is the default white balance setting when the VZ-9 is shipped.

"Auto Tracking" mode will

be reactivated).

The VZ-9 can be switched between "Auto Tracking", "One Push" and "Manual" white balance mode

in the on-screen menu (see page 10)

Place the slide onto the built-in light field, turn the camera head until the slide is in the middle of the recorded image and switch it on using the LIGHT key (#23). The camera zooms the slide automatically in. The camera automatically focuses on the slide.
