Figure 4-5 shows a simplified block diagram for using IMAQ1394 Grab
Setup and IMAQ1394 Grab Acquire.
Figure 4-5. Acquiring Images Using Grab
Sequence
A sequence initiates a variable-length and variable-delay transfer to
multiple buffers. Use a sequence for applications that process multiple
images. You can configure a sequence to acquire every frame or skip a
variable number of frames between each image.
Use IMAQ1394 Sequence for sequence applications. IMAQ1394
Sequence starts, acquires, and releases a sequence acquisition. The input
Skip Table is an array containing the number of frames to skip between
images. IMAQ1394 Sequence does not return until the entire sequence is
acquired.
