Summary
The Central Ballot Counter (CBC) device is used by an election official to do bulk scanning and interpretation of ballots. Interpretation is required for ballots that have apparent errors (e.g., possible over- or under-votes or stray marks) that are detected by the scanning software.
The CBC is comprised of CBC software (contained on
a boot disk created by the Device Manager) designed to work with a commercial off-the-shelf (COTS) high-speed optical scanning device, in order to provide the functions of a conventional Central Count Optical Scan (CCOS) device.
Unlike the PBC, however, the CBC software does not interact directly with the COTS scanner on a ballot-by-ballot basis; rather, a scanner is used to bulk scan a batch of ballots, creating a dataset of ballot images that the CBC software analyzes. Typically, each dataset will be a batch of ballots from a particular precinct.
The CBC software’s “duty cycle” begins when such a batch of ballot images is provided. The CBC software then performs digital image processing on each ballot, in a manner similar to the PBC software.
However, the CBC’s user interface is more complex, and intended for use by election officials. The CBC software finds ballot images with apparent under votes, over votes, stray marks, or other irregularities; each of these ballot images and automatic assess- ments are presented for human interpretation. The processing of the batch is not complete until an election official has interpreted each such ballot, confirming or overriding the automatic assessment.
At the end of a session, the CBC vote tallies for each contest, and produces audit logs that include each ballot image and the interpretation of the image, together with records the election officials’ decisions about apparent ballot irregularities identified by the CBC software.
As with the PBC, all of the information is written to write-once removable media, and no election information is retained on the hardware.
