IMAQ PCI/PXI-1407 User Manual
The NI-IMAQ driver software is included with your IMAQ device.
NI-IMAQ has an extensive library of functions that you can call from your
application programming environment. These functions include routines
for video configuration, image acquisition (continuous and single-shot),
memory buffer allocation, trigger control, and board configuration, as
shown in Figure 1-2.

The NI-IMAQ driver software performs all of the functions required for
acquiring and saving images. However, the NI-IMAQ software does not
perform image analysis. For image analysis functionality, refer to the
IMAQ Vision section in this chapter.
For maximum flexibility and performance, NI-IMAQ has both high-level
and low-level functions. The functions to acquire images in single-shot or
continuous mode are examples of high-level functions. Configuring an
imaging sequence is an example of a low-level function, since it requires
advanced understanding of your IMAQ device and image acquisition.
NI-IMAQ internally resolves many of the complex issues between the
computer and your IMAQ device, such as programming interrupts and
DMA controllers.
NI-IMAQ is also the interface path between LabVIEW, LabWindows/CVI,
or a conventional programming environment and the IMAQ device. The
NI-IMAQ software kit includes a series of libraries for image acquisition
for LabVIEW and Measurement Studio, which contains libraries for
LabWindows/CVI, Visual C++, and Visual Basic. These libraries are
functionally equivalent to the NI-IMAQ software.
