Capture Mode

Definition: Capture Mode relates to the way that images are captured and processed.

Default: Continuous Capture
Options: 0 = Rapid Capture
Rapid Capture
Definition: In a rapid capture mode, one or multiple captures (as many as 32) can be
taken at an interval specified by the time-between-captures parameter. In
this mode, the only limiting time factor is integration and transfer timing.
Continuous Capture
Usage: Continuous Capture is useful in applications with slower line speeds or
where symbol spacing may be random or not time-dependent.
Definition: In Continuous Capture Mode, image captures are taken throughout the
read cycle in a multi-buffered format (see diagram below). The reader
begins processing the first captured image at the same time that it captures
the second image. Captures will continue occurring throughout the read
cycle until an end condition occurs, such as a timeout, a new trigger, the
last frame in a capture sequence, or a combination of the above.
