Hello, We have a few options that we might be able to use depending on what video capture card you have. If you are using a National Instruments frame grabber to acquire the images, then this will integrate easily into LabVIEW. You can use any number of shipping examples and VIs to acquire the images or video and then save and display them.
If you are using a 3rd party capture card, then, unless that company has provided VIs or DLLs that allow you to acquire and save the images, then most likely it will be difficult to create a program to acquire the images from this card into LabVIEW. The best way to do this may be to use the software or functions that came with your video card to save the images to file. Once you have saved them, you can use LabVIEW to open the images, display them, and (if you have Vision) do all types of processing of the image. Again, the hardware you have and the software/functions provided with it will dictate how easy it will be to incorporate it into LabVIEW and develop a single application to acquire, save, and display these images. I hope this helps and gives you a few ideas of what can be done and what you need to look into. If you still have any questions on what the IMAQ functions in LabVIEW can do, then let us know and we will see what else we can do. Regards, Michael Applications Engineer National Instruments
