    Abstract: Devices, systems, and methods for providing illumination during operation of an indicia reader are described herein. An example system includes at least one imaging assembly; controller; and processor configured to: (a) initiate a ranging operation; (b) based on the ranging operation, determine a range value associated with a distance between the imaging assembly and an object in the field of view (FOV); (c) initiate a ramping operation comprising: (i) initiate a ramping sequence for the imaging assembly which captures plurality of images comprising image data of an environment appearing in the FOV using an associated plurality of focus parameters; and (ii) energizing an illumination assembly to provide illumination of the FOV during the ramping operation, the illumination intensity determined from the range value, the illumination intensity maintained substantially constant during at least a majority of the ramping operation; and (c) terminating the ramping operation based upon a termination signal.

    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: 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: At least some embodiments of the present invention are directed toward optical arrangements for use in providing illumination light emitted by a barcode reader. In some embodiments, the arrangement includes an illumination source, a lens positioned within the path of the illumination light emitted by the illumination source where the lens is operable to collimate the light and redirect its central axis, and a window positioned within the path of the redirected and collimated light where the window is operable to alter the illumination light such that the resulting illumination light beam has a height-to-width ratio of less than 8 to 25.

    Abstract: The disclosure is an imaging system for use in a variable focus indicia reader having a controller configured to activate and deactivate a light source, an imaging assembly configured to capture imaging data of an environment appearing within a field of view of the imaging assembly, and a focus module configured to set a focus characteristic of the imaging assembly. The focus module may set the focus characteristic based on (i) an image processor successfully determining a distance to a target or (ii) ambient lighting conditions exceeding a predetermined threshold.
