Big sensation at Infocomm 2002 in Las Vegas
WolfVision's
presentation of a prototype of a Ceiling Visualizer was one of the big
highlights at this year's Infocomm in Las Vegas in June 2002. The booth
was crowded all the time and everybody wanted to see it.
The
story behind it:
A
familiar line to many WolfVision salesman in the last couple of month
was "Your Visualizer VZ-27 (or VZ-8...) is a great unit, but can
you integrate this into the ceiling? We want to keep the table free".
For many years
building a document camera into a ceiling was a very difficult task,
because there always had to be either a suspended ceiling with a big
hole or a strange looking box on the ceiling.
The position of
the ceiling camera always 100% fixed, therefore the table could not
be moved.
Designed like a projector
WolfVision did
not want to make a simple "ceiling camera" - it had to be
a "Ceiling Visualizer", adding some innovative and unique
features to the unit.
The Ceiling Visualizer
is designed like a projector. It can be used with a standard projector
ceiling mount, or with WolfVision's own ceiling mount allowing to shift
the Visualizer 20cm (8") back-forth, turn it 360 degrees horizontally
or 30cm (12") up or down. There is no need to cut a hole into the
ceiling. The Visualizer can be placed side by side with the projector
on the ceiling.
Synchronized lightfield
for easy positioning of objects
The most popular
feature of Wolfvision's professional Visualizer series has been adapted
for the Ceiling Visualizer VZ-C10. The Synchronized Lightfield marks
the pick-up area of the camera. This makes it very easy for a presenter
to place his objects. The lightfiled on the table shows where the pick-up
area of the camera is. The size of this lightfield changes when zooming
in and out.
The new system
of light/image synchronization is jet another patent for WolfVision
in this area.
Advantages of a ceiling Visualizer
- There is nothing
on the table
- Nothing disturbs the view between speaker and audience
- No cable from the table to the ceiling
- Objects can be even larger and higher
- With an optional lightbox you can pick up the largest x-rays (17"x14")
- With the new light and scanning path and the flexible adjustment of
the ceiling mount, reflections can be minimized.
A "VZ-27 on the ceiling"
The features of
the Ceiling Visualizer VZ-C10 will be almost identical to the Professional
Visualizer VZ-27
- High resolution
1-CCD Progressive Scan camera
- SXGA/XGA/SVGA output (RGBHV and DVI)
- Image turn mode for high resolution capturing of full vertical (portrait)
pages
- Extremely high depth of focus (even higher here!)
- (almost) shadow free illumination
- (almost perfect) illumination of hollow objects
- Converted PAL/NTSC video outputs
- USB and RS232 connection
- Upgradeable firmware
- Live image with 20 pictures per second
- Computer input (loop-through)
- 9 picture memory (with split screen)
- Optimized signal for video conferencing
- Text enhancement mode
- Negative, Negative/Blue and black/white image
- No disturbing stray light for the projection screen
- No blinding the presenter or the audience
- Infrared remote control
... and many more ...
17x zoom (8.5x optical
and 2x digital)
The VZ-C10 is equipped
with two very professional 8.5x zoom lenses (camera lens and light lens).
Both of them are Wolfvision developements. The camera lens is perfectly
suited for the high resolution of a progressive scan camera. A very
sophisticated 2x digital zoom enhances the zoom factor to 17x, with
only a minor loss of resolution in the digital zoom area.
