15. The imaging scanner of claim 12 , wherein the processor is configured to determine that the confidence value is within in a range, with a lower end of the range indicating a lower level of certainty with respect to the accuracy of a corresponding character in an associated string and a higher end of the range indicating a higher level of certainty with respect to the accuracy of the corresponding character in the associated string.
12. An imaging scanner comprising: an image capturing component configured to sequentially capturing two or more images of a single document; and a processor configured to: identify a first location in a first captured image where information to be decoded is located, analyze each character in the first location, and produce a first string including both a corresponding character and a first confidence value for each character in the first location; determine that a first measurement of the confidence values in the first string is beyond a range associated with a first confidence threshold; identify a second location in a second captured image where information to be decoded is located, analyze each character in the second location, produce a second string including both a corresponding character and a second confidence value for each character in the second location; compare the first confidence value for each character in an identified location in the first string with the second confidence value for the character in the same identified location in the second string; select a character from one of the first string or the second string with a higher confidence value; and produce and output a combined string including the selected characters.
