Overview of NI-IMAQ VIs

LabVIEW is a development environment based on graphical programming. In contrast to text-based programming languages, where instructions determine program execution, LabVIEW uses dataflow programming, where the flow of data determines execution. The NI-IMAQ VI Library, a series of virtual instruments (VIs) for using LabVIEW with your image acquisition device, is included with the NI-IMAQ software.

NI Vision for LabVIEW is an image processing and analysis library that consists of more than 300 VIs. Some of the basic NI Vision VIs are shared with NI-IMAQ. If you use these basic functions, you can later upgrade your programs to use NI Vision without any changes to the image acquisition VIs.
