How can i take more frames per second with IMAQ USB and webcam?

[Kaliban]

Doing my thesis work (real-time positioning with camera) and trying to figure out how can i get more frames per second so object's position information would be more real-time? Right now i can get only one frame per sec.

Well, how are you doing it now?  Are you using LabVIEW? IMAQdx?  Those are probably the best option, but there are a lot of others.  Can you give a brand/type of camera?

In any case, you should be able to get a much better frame rate.

Oh sorry, i forget to tell some details. I'm using LabVIEW  & Vision Assistant 2009 eval. version. And the webcam is "neverheard" Micro-One MOWC-305. Basic idea is that the USB-camera brings picture from so-called football field (its white paper) and i move object (small ball) in that area. "Pics" goes to vision assistant where the program calibrates and matches pattern and finally brings the information out by couple of index arrays and and stuff.

So your actual problem is analysis time, not camera frame rate.  Without any analysis, I assume you can acquire at a pretty good rate.

For the analysis, the only thing I can suggest is to try to find ways to do it faster.  Some very similar routines take very different amounts of times.  Time also depends on your parameter values.  For example, a rake that examines every line is much slower than a rake that examines every fifth line.  Pattern matching can take a while when searching a large image for the pattern.  If you have a way to reduce the area it searches in, that will speed things up.
