Grab Acquisition

Use two VIs—IMAQdx Configure Grab and IMAQdx Grab—for a grab acquisition in LabVIEW. Call IMAQdx Configure Grab once to open the acquisition and start capturing the image to an internal software buffer. You can call IMAQdx Grab multiple times to copy the image currently stored in the internal buffer to a LabVIEW image buffer. After the program finishes copying images, call IMAQdx Close Camera once to shut down the acquisition.

The following figure shows a simplified block diagram for using IMAQdx Configure Grab and IMAQdx Grab.
