Looking for a module (or anything) to grab a webcam image

A perldoc -q query didn't turn up anything camera- or webcam-related
that looked useful; neither did a CPAN module search nor a Google Groups
search or a Google Web search.

What I'm trying to do is grab a still image from a USB camera and save
it to an image file. Either a Linux- or a Win32-based solution would be
acceptable.

Perhaps there's some notion of the ability to "capture" the data stream
from a USB port and save the result as an image file, but I'm not sure
where to start that line of research.

Can anyone point me in the right direction?

Oh Really. Searching CPAN for 'video' or the Internet for
ohhh.. "webcam capture image" didn't find anything useful?
How strange.. Doing just that I see a lot of possibilities.

OK, OK, there was Video::Capture::V4l::Imager at CPAN (I did find that
before posting.)

As for your other recommendation, I thought the fact that I was asking
the question in a Perl/perl group would obviate the fact that I was
searching for a perl solution to my problem. Try Googling /"webcam
capture image" perl/ and see what I mean.

So, let me restate my question:

Is there any perl-ish way to capture a USB webcam image and save it to a
file?

Has anyone used Video::Capture::V4l::Imager? I'd just install and start
mucking around with it, but I'm at work now and just thought I'd test
the waters here for some ideas.

Hmm ... thanks. Didn't think about the fact that I'd been plonked in
that exchange. I've learned a lot in two years, but I don't suppose that
will go very far here.

In case there's any chance at all of anyone answering my question, I'll
repost:

my $jpeg_data = `vendor_provided_capture_program.exe`;

Very perlish: take the lazy way out when there's an existing program
that will do the dirty work for you.
