Hello.
I have attached a little example mockup of taking an ROI and using it to extract a piece of an image to a second image. Basically, (using LV 7.0 or later), you can get the ROI property from the image display, then use the ROI to Rectangle function to convert it to a bounding rectangle, then you feed that information into an IMAQ Extract VI, which takes a portion of an image and copies it into a destination image.
This should get you on your way.
