Chapter 2 Basic Acquisition with NI-IMAQ for IEEE 1394 Cameras

Sequence

A sequence acquires a specified number of internal buffers and then stops.

Figure 2-4 illustrates the typical programming order of a high-level

sequence acquisition.

Figure 2-4. High-Level Sequence Flowchart

Use a sequence in applications where you need to process a series of

consecutive images. Sequence acquisitions are synchronous. If you do not

specify a session, a temporary session is created using

cam0.

Low-Level Function Examples

Use low-level functions for more advanced programming techniques. In

general, low-level functions have more parameters than high-level

functions.
