摘要： A solid-state imager is mounted at a point-of-transaction workstation for capturing images of one- and two-dimensional indicia and is operated at high speed to resist image blurring due to relative movement between the target and the imager. Dedicated hardware assistance and computation resources are allocated to decode multiple, continuous and simultaneous video streams from multiple imagers at the workstation.

摘要： Methods and apparatus for providing dynamic signal processing with, in one exemplary embodiment, a fast swipe image scanner. Dynamic signal processing comprises determining the rate of motion of a dataform, for example a barcode, which is passed in front of the scanner's data collection module. Then, based on the rate of motion, applying a signal processing method to the dataform. The complexity of the selected signal processing method used to decode the dataform can be chosen based on the detected rate of motion of the dataform. In alternate embodiments two or more algorithms are processes concurrently.

摘要： A method and apparatus for identifying and reading a postal code (12) with ascender bars (4), descender bars (5), full bars (6), and clock bars (7), includes a hand held code reader (10). An image of the postal code is reprocessed by determining the orientation and position within an image and then is read and decoded. The system is capable of discriminating between different formats of code patterns.
