I need to obtain video frames in real-time video. I have the Image Acquisition Toolbox (R2011b). How can I write code to automatically open the Image Acquisition Toolbox and start making video?

Did you run imaqtool and see what commands it logs as you do things? Commands like preview() and getsnapshot()?
