Chapter 2 Basic Acquisition with NI-IMAQ for IEEE 1394 Cameras
© National Instruments Corporation 2-11 NI-IMAQ for IEEE 1394 Cameras User Manual
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.
