    Abstract: Methods and systems to focus an imager for machine vision applications are disclosed. A disclosed example machine vision method includes: capturing, via an imaging assembly, an image of an indicia appearing within a field of view (FOV) of the imaging assembly; recognizing, via a controller, the indicia as a focus adjustment trigger, the focus adjustment trigger operative to trigger an adjustment of at least one focus parameter associated with the imaging assembly; adjusting the at least one focus parameter based at least in part on the indicia; locking the at least one focus parameter such that the at least one focus parameter remains unaltered for a duration; and responsive to the locking of the at least one focus parameter, capturing, via the imaging assembly, at least one subsequent image of an object of interest.

    IPC: H04N5/232

    CPC classification number: H04N5/23212

    Abstract: A system and methods for performing focus tuning of an imaging system. The method includes an image sensor obtaining a plurality of images, with each image obtained at a different focus of a tunable optical element. A processor identifying a reference element in at least one of the images of the plurality of images. The processor then determines a reference image that includes the reference element and identifies a reference focus of the tunable optical element. The processor then stores the identified reference focus in a memory.

    Abstract: Machine vision devices with configurable illumination and aiming pattern generation are disclosed. An example system includes a housing having a cavity; an imaging sub-assembly mounted in the cavity including: an imager configured to capture an image; an aiming light source mounted in the housing configured to generate a collimated beam of light, an illumination light source configured to generate illumination light; and interchangeable first and second cover plates configured for mounting to the housing in front of the imaging sub-assembly to form an external cover for the housing and sealably protect the imager from an environment, wherein the first and second cover plates have respective passive optical elements that modify the collimated beam of light to form respective aiming patterns, and wherein at least one of the first cover plate or the second cover plate has a third optical element that modifies the illumination light.

    Abstract: Methods and devices for performing color imaging processing on the fly for barcode readers are disclosed herein. An example method includes color image processing in a barcode reader to identify one of raw image data or processed image data and further decoding indicia in the identified raw or processed image data. The method includes receiving a raw image data of an image of an object, performing image processing on the raw image data, analyzing the raw image data and the processed image data, and identifying which of the raw image data or processed image data to communicate to a decoder for further decoding. The decoder then identifies, in the identified raw image data or processed image data, indicia corresponding to an object, and decodes the identified indicia.
