Autodiscrimination and line drawing techniques for code readers |
摘要 |
The disclosure relates to optical image readers having a two-dimensional image sensor and an auto-discrimination function. The auto-discrimination function identifies optical codes by type for pixel clusters and, in some cases, tilt angle and start/stop coordinates. The clustered pixel data is passed to an appropriate decoder identified by the auto-discrimination function based upon a likelihood that the cluster contains an optical code of a particular type. Line drawing techniques provide for adequate sampling of the clustered pixel data code based on the tilt angle of the code relative to a image sensor array.
