About Document Camera
"Seeing
is Believing!" No need to waste valuable presentation time fiddling with
that bulky overhead projector! Whether in the classroom, boardroom, or
courtroom, today's presentations require far more functionality and clarity than
can be accomplished with an overhead in order to be effective. Through AVerMedia
digital document cameras and visual presenters, visual communication and
interaction between the presenter and audience have never before provided more
impact.
A
typical document camera or a visual presenter uses a camera, commonly extended
on a mounted arm, to capture images of text, 3D objects, 35mm slides and other
transparencies, microscope slides, videoconferencing participants and just about
anything else you can think of, and then sends these images to a monitor or
projector for all to see. Instantly, you can place these images in front of an
audience, or record and save images to be distributed or recalled later. Like a
camcorder, it has handy features such as zoom, auto focus, and exposure
adjustments. A light module illuminates when the room is poorly lit, while a
built-in or plug-in light box illuminates 35mm file slides, x-rays or film
negatives. Various output connections such as DVI, VGA, s-video and composite
gives users the ability to display documents, 3-D objects, microscopic images,
x-rays, negatives and photos on a large screen TV, monitor or projector.
Lawyers
use document cameras or visual presenters. So do doctors, scientists, engineers
and, of course, teachers to effectively present physical testimony to strengthen
verbal ideas and interact with audiences. Science teachers are using a document
camera for their routine demonstrations and, especially, for sharing their most
minuscule subject matter with the help of the available microscope adapter.
