Abstract: Methods and apparatus for scanning swiped barcodes are disclosed. An example method includes in response to detecting an object, capturing first images while focused at a swipe focus distance representing a pre-determined expected swipe distance range within which a scan target is expected to be swiped across a FOV. In response to a barcode decoded based upon the first images, exiting the swipe decode phase. In response to no barcode decoded during a time period representing an expected amount of time during which a scan target is expected to be swiped across the FOV, exiting the swipe decode phase and initiating a re-presentation decode phase including sequentially focusing the imaging scanner at a plurality of pre-determined, re-presentation focus distances, capturing one or more second images at each of the plurality of pre-determined, re-presentation focus distances, and, attempting to decode a barcode in one or more of the second images.

Abstract: Methods and apparatus for locating small indicia in large images are disclosed herein. An example method includes: identifying an aiming pattern zone that includes a detected or presumed location of an aiming light pattern, wherein an offset between the location and a center of image data varies due to a parallax; determining one or more coordinates of the aiming pattern zone; capturing image data representing an image of an environment appearing within a field of view (FOV) of a handheld scanner including the indicia; encoding the one or more coordinates into a tagline of the image; and providing the image with the tagline to an indicia decoder such that the indicia decoder attempts to decode the indicia from the image data starting in a region of the image data selected based upon the one or more coordinates.

Abstract: Method and systems for driving an aiming assembly of a barcode imager are provided. An example method includes obtaining an operating mode of the barcode imager having an aiming assembly and, in response, determining a duty cycle of an aiming pulse of the aiming assembly. That duty cycle is determined as a percentage of a frame duration of an imager sensor and, further, such that simultaneous constraints are satisfied by the aiming pulse. The constraints include a simultaneous frame duration-independent, peak pulse optical power constraint and a frame duration-dependent heat dissipation constraint.
