Chapter 2 Basic Acquisition with NI-IMAQ for IEEE 1394 Cameras
NI-IMAQ for IEEE 1394 Cameras User Manual 2-8 ni.com
Table 2-2 lists common video modes and their corresponding image types
after being decoded by NI-IMAQ for IEEE 1394 Cameras.
Decoding images requires CPU resources. However, many of the decoding
algorithms have been optimized in the driver. If you do not want decoded
image data, you can use NI-IMAQ for IEEE 1394 Cameras to get a copy of
the raw camera output.
Programming Examples
This section contains examples of high-level and low-level image
acquisitions. Refer to the Example Programs section of Chapter 1,
Introduction to NI-IMAQ for IEEE 1394 Cameras, for directory paths to
the code examples discussed in this section.
High-Level Function Examples
Use high-level functions to write programs quickly without having to learn
the details of the low-level API and driver.
