Is there a way to inerface a Webcam or a pc TV board with Labview with only there drivers?

there are some pc card on the market that gives turn your computer into a TV. I was wondering if I can get this signal from the card and use LAbview to store it as JPEG (take each frame of that signal let say). Also I have a Webcam and I am wondering how can I make that webcam to work with labview.

There are number of posts on the deveolper exchange about using LabVIEW with webcams. Here is one post that has some VIs.

I think that for playing video files with LabVIEW you would need our Vision software, but I am not sure about getting JPEGs from a video signal.

The webcam, I have been able to interface the Logitech Quickcam with labview
via ActiveX. The only problem is that since Labview doesn't understand
pointers, I haven't been able to fetch pictures straight to memory. Instead
the control saves the picture to disc, then you would have to read in the
saved file.

As for the PC TV card, I'm not familiar with any options. I've seen a lot of
NTSC frame grabbers on the market as well as the ATI all-in-wonder cards,
but I've never checked to see if they can be automated via activex.

Hi,

I'd suggest also this site:

You can download a free version of this remarkable IVision package.
I've tested it with 3 different webcams and was definitely impressed.
