Acquire image from USB webcam

[endmile]

Hey everyone.  I have a Logitech USB webcam that I would like to use to acquire still images.  I am using LV 8.2.  All the posts I have read suggest using NI-IMAQ for USB Cameras.  I have tried to install it, but it says "You must have Vision 7.1 or higher with LabVIEW 7.0 or higher, or you must have Vision Assistant 7.1 or higher installed to use this add-on."  I don't have Vision or Vision Assistant.  Am I doing something wrong?  None of the other posts seemed to mention that you needed Vision in order to use the add-on.  Does anyone know how I can acquire images from my USB webcam through LV 8.2 without having to buy additional software?  Thanks!

This question comes up often. That driver is something that NI provides as a convenience, and yes it requires additional software, as stated on the description for it. As for alternatives, did you get any software with the camera that looks like it could be used with LabVIEW, like an ActiveX library? That can certainly be used. As mentioned in this thread, supposedly RoboLab for LabVIEW has some tools, but I've never used it myself. You can also try the LabVIEW Webcam Library. Kind of old, though.
