Yes, inasmuch as the Quickcams have a PIC in them, and I've used a PC
running ISPY or Webcam32 and a modem.
Unless you add a bit of hardware to the PIC, it would be a clunky setup to
do it with a camera, PIC, and modem.(without a PC). You'd have to do the
dialup, then using the limited amount of ram in the PIC capture a line of
video or a portion of a line, send it out the modem, count lines until you
came around to the next line, grab that one, etc. Your picture would be
made of video lines taken over the course of a minute or so, or however
long it took to modem out the data.

How about hacking one of those "Snappy" devices? They must already have a nice
frame buffer. Add a cheap CCD camera and an *external* modem and you are in
business! A larger MCU such as an 80C51 or 68HC11 might be more appropriate tho
ugh,
but I bet you could still get by with a PIC as long as the frame buffer was exte
rnal.

Yes. My current project is a videoconferencing camera which uses a PIC
to control the system. The video compression is done on a 250MIPS embedded
StrongARM -- it could theoretically be done on a PIC but not very easily. This
is 320x200x30fps though.

Your best bet is to get a ready made camera/capture system (like ours, but
that's not yet for sale) and to interface it to a PIC which controls a modem
chipset. Especially digital still cameras should be not too difficult (they
have JPEG compression built in).
