What is the document camera, document scanner ?

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) December 22, 2011 -- Document camera = Optics + Camera + Lighting system + Motherboard and firmware.

A document camera, also called a digital visual presenter, visualizer or document scanner, is one of the latest ways to add interactive and exciting visual technology to your presentation,
whether it be in a classroom, training room, video conferencing suite, boardroom or courtroom. Document cameras are the latest electronic imaging devices which can be used to display real three dimensional objects, pages from a book, artwork or even people!

Most document cameras can also be supplied with an accessory so that they can be used with a microscope.
According to recent research by Futuresource Consulting over 11k visualisers were sold in UK in 2008 and Futuresource forecasts that over 17,000 will be sold in 2009.
The market is valued at £12 million in 2009 increasing 53% in 2010 to £18 million. One in 30 UK school classrooms now have a visualiser. That is expected to increase to 1 in 10 by 2010.

Typical applications for a document camera include:
Presentations (anyone giving a presentation can add interactivity and excitement using images captured using a document scanner)

education institutions (document scanners can be very useful for stimulating students and keeping them engaged)
company providing training services (document scanners are perfect for displaying training material to a class)

Anyone using video conferencing (document scanners can be used in combination with video conferencing equipment to share live images of 2D or 3D objects with conference participants)
