Extremely High Resolution - Native SXGA- and 720p High Definition
The most important new feature of the “third generation” of VZ-8 Visualizers is the upgrade to a higher resolution CCD camera with 1280 x 960 pixels and 30 frames per second. This is native SXGA- resolution with an aspect ratio of 4:3.
The camera also outputs native 720p HD (High Definition) with 1280 x 720 pixels at a widescreen aspect ratio of 16:9.
The VZ-8plus3 and VZ-8light3 offer 750 lines of resolution. Naturally these 750 lines are visible in every part of the picture, including the edges, as WolfVision only uses high-end lenses.
Besides the native image formats SXGA- and 720p HD, both Visualizers can also output the image scaled to XGA and WXGA. The quality of the scaling is exceptional. The signal is better than with an original XGA or WXGA camera.
Additional image formats of the Visualizer VZ-8plus3 are SXGA+, SXGA and SVGA. Plus it can also output the original Progressive Scan signal converted into PAL or NTSC video (switchable).
All widescreen projectors, monitors or plasma displays on the market can display at least one of these standards.
All current WolfVision Visualizer models can pick up 30 pictures (frames) per second in every resolution. There is almost no difference in the smoothness of motion, when compared to PAL/NTSC video cameras. But the resolution is much higher!
Connectors / DVI-port
VZ-8plus3 and VZ-8light3 output the image on RGB (15-Pin D-Sub) and DVI outputs.
(The DVI port on the VZ-8light3 is a new feature of the "third generation". There was no DVI port on VZ-8light2.)
Auto Resolution: The Visualizer recognizes units connected to the DVI and RGB output and automatically selects the perfect output mode.
Camera Head / Zoom Wheel / Easy Handling Concept
For smooth presentations, it is necessary that the Visualizer is very easy to use. Everyone should be able to operate the unit immediately, without any instructions.
Normally users need only to use the zoom wheel on top of the camera head. Everything else (focus, iris etc.) is adjusted automatically.
The zoom wheel offers the possibility to zoom with two speeds.
The other 5 keys on the camera head include important functions like autofocus on/off, manual focus, freeze and Ext/Int. More functions are available on the remote control of the VZ-8plus3.
No Focus Adjustments Necessary
The continuously working autofocus recognizes every object quickly and precisely. As a result, the presenter never needs to worry about focusing. The high speed of the autofocus is due to a special WolfVision software, which is analyzing 30 frames per second.
For special objects, a manual focus is also available.
No Light Adjustments Necessary
The light system is optimized for the working surface and there is never a need for any light adjustments. The camera arm can be moved up and down at an angle of 90 degrees. The light is fixed onto the camera arm and moves together with the camera. Therefore, it is also possible to illuminate the area in front or behind the working surface. The light of the Visualizers is focused on the working surface. Neither the audience nor the speaker will be blinded in a darkened room and there is no disturbing stray light from the Visualizer on the projection screen.
For recording objects at greater distances to the device, the close-up lens of the Visualizers can be hinged away from the camera. It won't get lost because it remains attached to the unit.
Recordings Behind the Unit
When objects are too big to be placed on the working surface or need to be shown from the side (like glasses of liquids etc.), the camera head and the light of the portable Visualizers can be turned to accommodate them.
In this way a Visualizer can be used like a video camera, to record people, large objects, pictures or charts in a room.
Recordings in Front of the Unit, with Image Flip
The Visualizer can not only record objects from behind the unit. The camera head can also be turned to record in front of the unit.
This is perfect for recording a speaker or charts on a wall behind the speaker. When the camera is turned to record in front of the unit, the image is automatically turned around 180 degrees ("image flip"), because normally such recordings would be upside down.
Not many Visualizers can record outside of the working surface because tilting the camera and light requires high-grade mechanical components.
WolfVision's VZ-8 series Visualizers feature a very sophisticated camera/light hinge which provides a large shooting area outside of the working surface.
The total tilt range of the camera is 220 degrees.
The camera can be tilted 100° towards the audience and 120° towards the speaker.
Unique Folding System / Set up in Seconds
The Visualizer can be set up in seconds. A gentle tug lifts the arm and light into the working position. The user then needs only to turn the camera head to the desired viewing angle. Just as easily, it folds back into its compact size with just one pull on the center ring, to be neatly stored during or after a presentation.
The units fit perfectly in a drawer. The height when folded is only 122mm / 4.8" (same outside dimensions as previous units).
100% Reflection free Working Surface / Slide-through
Due to the clever design of the Visualizer's housing, the whole working surface is completely reflection free. In the upper part the working surface, where the light is normally reflected into the camera, the surface is slightly curved, so that reflections are not possible on any part of the working surface.
The flat design also allows moving objects around on the whole working surface without any obstacles. Even oversized documents (like the calendar seen in the picture on the left) can be moved to the back without being blocked by the device.
Firmware Updates through RS232 or USB
WolfVision's Visualizers are the only units on the market that offer upgradeable firmware. This allows new features and technical improvements to be added at no cost!
Downloading firmware updates from the internet and uploading them onto a Visualizer can be done in 2-3 minutes, with just 4 mouse clicks, using the latest version of WolfVision's Connectivity Software.
Firmware Updates can be made using the Serial (RS232) or USB port of the Visualizer.
WolfVision's engineers are constantly working on new improvements and features to keep your units up to date with the technology of tomorrow!
USB 2.0 Port / Twain / Video Capture / AVI
The USB port 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 be used as scanners for 3-dimensional objects.
WolfVision's USB Software (Connectivity Software) works under Windows 2000, XP and
WolfVision Visualizers are equipped with a fast USB 2.0 port. This allows for uploading images onto a PC in a fraction of a second. It can also output live motion. The WolfVision Connectivity 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.
Slides can be picked up in exceptional quality without an external bottom light by just putting them into the slide drawer on the camera head of the VZ-8plus3.
"Image Turn" Mode for Higher Resolution
Picking up a complete vertical (portrait) letter or A4 sized page has always been a critical issue for a Visualizer because the image has always been picked up in a horizontal (landscape) format. As a result, only 50% of the camera pixels could be used to pick up the vertical (portrait) document.WolfVision's unique "Image Turn" mode solves this problem. The user places the document on the working surface horizontally and zooms in on it completely. In doing so, approximately 90% of the camera's effective pixels are used to pick up the document. WolfVision's state-of-the-art electronics turn the image to a 90 degree angle and output it in a vertical format with 40% higher resolution. The margins left and right are blacked out.
In this mode, the resolution of a complete vertical (portrait) document is much better. Even 8-point characters are now readable.
Another advantage of the image turn mode is that very long vertical pages (like
24x Zoom (12x Optical and 2x Digital)
A large optical zoom range is one of the most important features of a Visualizer. It is absolutely necessary that objects in every size can be picked up in full resolution. WolfVision's optical 12 times zoom offers the possibility to pick up objects as large as an open book (370 x 276mm / 14.6" x 10.9") and as small as a stamp (33 x 25mm / 1.3" x 1") in full size to fill the screen. For enlarging even smaller objects down to 17 x 13mm (0.7" x 0.5") the Visualizers also offer a 2x digital zoom. This enables users to enlarge objects such as a very small coin.
Due to the large range optical zoom, it is not necessary to use much of the digital zoom, so in most cases, you can work with full resolution.
9 Picture Memory
The VZ-8plus3 can store 9 images and recall them by just pressing one of the numerical keys on the infrared remote control.
By pressing the "All" key, a split image with all 9 pictures of the memory can be displayed, enabling easy selection. The 9 pictures in the memory can also be downloaded to a PC via USB and they remain in the memory even when the power is disconnected.
The VZ-8light3 offers a 1 image freeze function, instead of the 9 picture memory.
Special Surface for Transparencies
All WolfVision Visualizers have a special crystalline white working surface for perfect reproduction of transparencies. The quality of a transparency on this surface is even better than with a bottom light, because there is more contrast and the colors are not "washed out".
The whole working surface has the same even color thus providing the perfect background for transparencies and other objects.
For x-rays or oversized slides, external lightboxes are available.
Optimized for Video Conferencing
WolfVision's camera electronics produce a very strong and stable picture, which is very important when a Visualizer is used as a document camera for videoconferencing systems.
The even lighting, smooth auto iris and perfect focus are very important features, enabling video conferencing systems to digitize and transfer the picture from a WolfVision Visualizer much faster than pictures from other document cameras. Furthermore there is no blinding stray light from a WolfVision Visualizer, which could disturb the auto iris of the room camera.
Of course these features are equally important for live image presentations with a data projector and for other Visualizer applications. Due to the "Image Flip" feature the Visualizers can also be used as an additional room camera of a videoconferencing system.
Computer Input (Internal/External Switch)
A computer can be connected to the RGB input (15-pin D-Sub-plug) of the Visualizer. With the Ext/Int switch, a user can switch between the Visualizer image and computer image to be output by the Visualizer's RGB output (15-pin D-Sub-plug).
Therefore, only one RGB cable is required to be attached to the display unit (projector, monitor, video conferencing system etc.) and no separate remote control has to be used for switching between the two image sources.
Text Enhancer / Negative / Negative-Blue
WolfVision Visualizers offer many possibilities to improve the readability of text:
With the "Text Enhancer" function, the outstanding contrast of the picture is improved even more with colors only slightly darker than before. Dark text on a bright background can sometimes be easier to read if the Visualizer is switched to "Negative" or "Negative/Blue".
For special applications (like analyzing x-rays), the image can also be switched to Black and White.
Infrared Remote Control
The VZ-8plus3 is supplied with a remote control. In addition to the features described above, the remote control also offers:
- Manual focus
- Auto focus on/off
- Manual iris
- 3 user programmable presets
- Laser pointer
- Easy navigation for on-screen menu and on-screen help
There are 3 different possibilities to control the Visualizers from external devices, such as a room control system, a video conferencing system or a computer:
- Serial RS232
The Visualizer has two anti-theft devices.
On the bottom of the working plate is a thread for attaching the unit to a table with the supplied Table Lock Bolt. T-Lock (Kensington® Lock) devices can also be used. The connection can be found on the bottom of the arm.
