Capture Mode relates to the way in which images are captured and processed.

Continuous Capture
0 = Rapid Capture
In a rapid capture mode, one or multiple captures 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 is useful in applications with slower line speeds or where symbol
spacing may be random or not time-dependent.
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.

Number of Captures is used to specify the number of captures to be processed in
Rapid Capture Mode.
Sets the total number of captures that are processed during a read cycle in Rapid
Capture Mode. This feature is used in conjunction with Capture Timing parameters
to specify the capture sequence of a rapid capture read cycle. This may be more than
the total buffers available and may require tuning to optimize large capture counts,
especially when more than the buffer count is requested. It may not be possible to
capture all images when such a large capture count is requested.
