Method and apparatus for performing different decoding algorithms in different locations

摘要

A method and apparatus for decoding codes applied to objects for use with an image sensor that includes a two dimensional field of view (FOV), the method comprising the steps of providing a processor programmed to perform the steps of obtaining an image of the FOV and applying different decode algorithms to code candidates in the obtained image to attempt to decode the code candidates wherein the decode algorithm applied to each candidate is a function of the location of the code candidate in the FOV.

1. A method for decoding codes applied to objects for use with an image sensor that includes a two dimensional field of view (FOV), the method comprising the steps of:
a) selecting, using a processor, a first decode algorithm for attempting to decode within a first defined region of interest (ROI) in the FOV and a second decode algorithm for attempting to decode within a second defined ROI in the FOV and outside the first defined ROI in the FOV, the first defined ROI having a first ROI boundary and the second defined ROI having a second ROI boundary that is different than the first ROI boundary, the first decode algorithm and second decode algorithm are different; b) subsequent to step a), obtaining, using the processor, an image of the FOV, the image including a first code candidate located in the first defined ROI or the second defined ROI; and c) attempting, using the processor, to decode the first code candidate when located in the first defined ROI using the first decode algorithm and attempting, using the processor, to decode the first code candidate when located in the second defined ROI and outside the first defined ROI using the second decode algorithm.
