Pre-Processing
Disabled
When Pre-Processing is disabled, the imager can process previously captured images
while image capture events are taking place. The benefit of this operation is that the image
capture events have minimal impact on image processing. Therefore, if the imager is
configured to capture 4 consecutive frames, but it is only looking for one decode, it could
process and decode a symbol on the first image frame before all 4 image frames were
captured. If Pre-Processing were enabled, the imager could not start processing an
image frame until all 4 image frames were captured (since they are consecutive captures).
Enabled
When Pre-Processing is enabled, the imager performs pre-processing tasks while an
image is being captured. Since some of the processing is complete when the image has
been captured, the time required to complete the processing of the image frame will be
less (approx. 10 ms/frame). However, while an image is being captured, the imager is
dedicated to operating on the current image being captured. This means that an image
capture event will impact the processing time of previously captured image frames. The
benefit of this mode is the decrease in capture-to-decode time.
Definition: When enabled, this feature reduces the time between image capture and
decode by beginning the processing task while an image is being captured.
