Hello,
As far as capturing physical transparencies, I am looking into
cconsumer digital cameras (2+ MegaPixels) that can be controlled via USB
or RS232. People have supposedly successfully controlled cameras this way
with Java and Linux (e.g. http://jphoto.sourceforge.net/ ). Anyway, you
could just (using e.g. Gaffer Tape) mount a cheap camera onto the arm of
an old overhead transparency projector, and make the camera take pictures
of the transparencies (e.g. 1 per second) and download them and then ship
them to the LCD projector or wherever. This is what we will be doing in
the coming months for our lecture-recording device.
This would be a cheap solution assuming you already have in place
a computer to control the camera and an LCD projector. Nice document
cameras are like over $2000 I think. And 2 MegaPixel images are probably
high enough resolution for anything you would need.
Jeremy
