Abstract: Methods and apparatus to determine barcode decoding parameters for a plurality of barcodes in an image are disclosed. An example method includes: obtaining image data representing an image including a plurality of barcodes; decoding a first barcode of the plurality of barcodes from the image data; determining a set of barcode decoding parameters used to successfully decode the first barcode; determining whether the plurality of barcodes encoded using at least one of a same barcode size, a same module size, or a same barcode format; and when the plurality of barcodes are encoded using at least one of the same barcode size, the same module size, or the same barcode format, attempting to decode all remaining barcodes of the plurality of barcodes from the image data using first the set of barcode decoding parameters.

Abstract: Methods and apparatus to locate and decode an arranged plurality of barcodes in an image are disclosed. An example method includes obtaining image data representing an image of an environment appearing within a FOV of an imaging device that includes the image sensor, wherein an arranged plurality of barcodes appear in the image. A first subset of the plurality of barcodes is decoded from the image data. One or more parameters representing a predicted arrangement of the plurality of barcodes in the image is determined based upon location information associated with each of the decoded first subset of the plurality of barcodes. Possible locations for respective ones of a second subset of the plurality of barcodes are determined based upon the one or more parameters, and the second subset of the plurality of barcodes are attempted to be decoded from the image data in vicinities of the respective possible locations.

Abstract: A method of activating an illumination assembly within a symbology reader is provided, the illumination assembly having a first illumination source and a second illumination source, the symbology reader having an imaging sensor configured to operate at a predetermined framerate where each frame includes an exposure period over which the imaging sensor is active to capture image data and a non-exposure period over which the imaging sensor is not active to capture image data, the method comprising: during a first frame, activating the first illumination source during at least a portion of the respective exposure period and activating the second illumination source over at least a portion of the respective non-exposure period; and during a second frame, activating the second illumination source during at least a portion of the respective exposure period and activating the first illumination source over at least a portion of the respective non-exposure period.
