Claims
- 1. In a bar code scanning system, a method for enhancing the decodability of label information from scans of label data comprising the steps of:
receiving scans of label data comprising character information encoded in one of a variety of potential symbologies; identifying leading and/or trailing quiet zones of the scans of label data received; determining the most likely symbology type comprising the scans of label data type from the variety of potential symbologies; and, selecting at least one decoding method to be implemented based upon the symbology type determined to be the most likely symbology type comprising the scans of label data.
- 2. In a bar code scanning system, a method for enhancing the decodability of label information from scans of label data comprising the steps of:
receiving scans of label data comprising character information encoded in one of a variety of potential symbologies; determining which of the variety of potential symbologies has the highest likelihood of yielding successful decoding of the scans of label data; and, selecting at least one decoding method to be implemented based upon the symbology type determined to be the most likely symbology type comprising the scans of label data.
- 3. The method of claim 2 wherein the step of determining which of the variety of potential symbologies has the highest likelihood of yielding successful decoding further comprises the steps of:
generating rating values for each of at least one indicator, wherein each indicator provides a relative indication of the likelihood of yielding successful decoding in relation to each of the variety of potential symbologies; and ordering the variety of potential symbologies with the symbology having the highest likelihood of yielding successful decoding ranked first and the symbology having the lowest likelihood of yielding successful decoding ranked last.
- 4. The method of claim 3 wherein the ordering of the variety of potential symbologies is determined through a weighted calculation of the generated rating values for each indicator and each of the variety of potential symbologies.
- 5. The method of claim 3 wherein the indicators comprise the start/stop pattern, the element width histograms, the number of elements in the label, the length of the label in time, the number of labels decoded for each symbology, the number of characters decoded in previous scans for each symbology, and character equality checks.
- 6. The method of claim 3 wherein the step of ordering the variety of potential symbologies comprises user programmed information regarding the likelihood of yielding successful decoding in relation to at least one of the variety of potential symbologies
