"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 US legal format) can be
picked up completely.
Computer Input (Internal/External Switch)
The USB output 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 Visualizers are equipped with a fast USB 2.0 port. This allows
for uploading images onto a PC in a fraction of a second.
Connecting slower computers with the older USB 1.1 standard is also no
problem. It still takes only a small fraction of the time a desktop scanner
requires to scan an image.
WolfVision's USB software works under Windows 98, ME, 2000, XP and
Apple Macintosh and is fully Twain compatible. This is important when
using the Visualizer in connection with popular graphic programs such as
Photoshop, or for connecting them to Interactive Whiteboards (Smart
Boards).
The fast USB 2.0 port can also output live motion. The WolfVision USB
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.
USB 2.0 port / Twain / Video Capture / AVI
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.
