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 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: Methods and systems to implement a miniature long range imaging engine with auto-focus, auto-zoom, and auto-illumination are disclosed herein. An example method includes detecting, by a microprocessor, a presence of an aim light pattern within the FOV; determining, by the microprocessor and in response to the detecting, a target distance of an object in the FOV based on a position of the aim light pattern in the FOV, the target distance being a distance from the imaging engine to the object; causing, by the microprocessor, a variable focus optical element to focus on the object based on the target distance; responsive to making a first determination, by the microprocessor, selecting, based on the target distance, one of a plurality of zoom operation modes; and responsive to making a second determination, by the microprocessor, selecting, based on the target distance, one of a plurality of illumination modes.

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.

Abstract: An optical assembly for an autofocus imaging system for capturing at least one image of an object appearing in an imaging field of view (FOV) is provided. The optical assembly includes a front aperture along an optical axis and a front lens group along the optical axis that receives light from the object of interest. The position of the front lens group is adjustable to change a focal distance of the optical assembly. The optical assembly further includes an actuator physically coupled to the front lens group that adjusts the position of the front lens. A rear lens group is disposed along the optical axis to receive the light from the front lens group, and an imaging sensor is disposed at a back focal distance of the rear lens group, to detect the light.

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: Devices having a long-range imaging engine formed of two cameras having different resolution are disclosed herein. An example imaging engine includes a front-end, with the cameras, terminated in a communication interface for coupling to an external host processor that performs image processor. The front-end has a near field image sensor and a far field image sensor, and a normalization processor to receive the respective image data from the sensors and normalize that image data prior to sending to the host processor. Normalization includes adjusting an image size, aspect ratio, or pixel count complying with data rate constraints imposed by the communication interface or the host processor.
