Continuous video w frame capture

[Eric]

I'm writing an art-related application that requires a continuous
video feed, with the ability to capture a snapshot frame on the fly.
Of course the first thing that occurred to me was to use a regular
webcam (probably Logitech C920), but even the better webcams may
degrade image quality significantly.

Are there any alternatives in the world of inexpensive video cameras?
Or maybe some still cameras can do something like this now? I don't
need audio. I'd like to minimize dimensional distortion if possible.
Fast frame rate would be nice, but not imperative.

Thanks for any ideas.

That's an interesting device! But does it do all recording internally,
or does it provide a continuous stream?

Take a look at some video security setups.

don't know if you have some answer, but modern web cam are better than
cheap video cams (and more expensive)

most canon camcorder can be connected to a computer through video, but
I don't know what they will do on *long* periods

My Canon T1i does exactly that, 1080p video and snapshot when you push
the shutter button, and I have used it extensively when shooting stuff
in a microscope. Use a USB cable to stream the video to a laptop.
