Visualizers have improved
the technical standards for Progressive Scan cameras even
more. All current Visualizer models can now pick up 30 pictures
(frames) per second. There is almost no difference in the
smoothness of motion, when compared to PAL/NTSC video cameras.
But the resolution is much.
The portable Visualizers 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. 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. |
