I am working on the project that I need to import images in real time. I mean my program have to get a picture per second.I am very new with LabView and don't know how can I do that. can anyone help me please?
Thank you in advance.

Lots of questions. Do you mean "Real Time" (as in running on its own processor with a Real Time Operating System, such as a PXI controller, a cRIO, other specialized hardware) or "really fast" (i.e. on a Windows PC)? Is there a camera involved? If so, is it a USB camera or Ethernet?
If you are "very new to LabVIEW", take the time to learn the basics before trying to tackle a moderately-advanced project such as this (or hire a LabVIEW Expert). There is plenty of good tutorial material on NI's site.

Thanks for the respond.
You're right Bob but I have no choice to not doing it. There is usb camera and I mean by real time is really fast like one picture per second.
I am good at programing but no experience with LabView. Do you think can I code separately in C or C++ and kind of using in LabView.
I am really appreciated for your help.

I have a USB camera mounted on my monitor "looking at me". I fired up MAX and tried to determine how quickly I could "snap" (take a single image) pictures. Since I was manually "pushing the button", it was tricky to tell, but it seemed to be possible to take 1/sec. I then tried "grab", which takes videos -- this was (of course) much easier, and considerably faster (I'd guess tens of frames/second).
I have the Vision module installed, and am using IMAQdx for getting the images. LabVIEW isn't bad in capturing images, but there's not a lot of hand-holding or extensive documentation -- I think it could be a real challenge to "do it yourself" with no LabVIEW experience.
To even see if this is a viable approach for you, see if you can repeat what I did -- plug in your USB camera, open NI-MAX, and see if the camera shows up. If it doesn't, stop -- you don't have the LabVIEW software appropriate to do this installed.
