Abstract: The present invention embraces an optical indicia reader, e.g., barcode scanner, that captures images of optical indicia under multiple imaging conditions within the span of a single frame. The reader includes an image sensor having selectively-addressable pixels that can be divided into groups having regions of interest (ROIs) within the reader field of view. Each pixel group is shuttered separately to obtain independent partial frame images under separate imaging conditions.

Abstract: Embodiments described herein provide a middle frame image processing schema in a multi-sensor environment, for example improve image processing throughput and snappiness by processing middle frame image data objects of a middle frame image size that is shared amongst a plurality of image sensors. An example apparatus includes a plurality of image sensors, each configured to capture a full frame image data object and output a middle frame image data object. The apparatus further includes an image frame multiplexer communicable with each of the plurality of image sensors, and configured to receive a plurality of middle frame image data objects, and output a selected middle frame image data object from the plurality of middle frame image data objects. The apparatus further includes a processor communicable with the image frame multiplexer, and configured to receive the selected middle frame image data object, and process the selected middle frame image data object.

IPC: G02B7/04
Abstract: Various embodiments described herein provide a discrete focusing lens assembly. Some embodiments are designed to enable repositioning of one or more components, such as a lens barrel assembly, to adjust the focus of the discrete focusing lens assembly. Some example discrete focusing lens assemblies include a module base housing a lens barrel assembly having a pair of positioning magnets, a pair of positioning coil assemblies associated with the positioning magnets, and at least one module alignment pin positioning and/or aligning some or all of the components. The positioning coil assemblies together with the positioning magnets are configured to exert various magnetic fields to reposition the lens barrel assembly. Further embodiments are provided for imaging apparatus including at least one discrete focusing lens assembly described herein. Further, embodiments are provided for processes for assembling a discrete focusing lens assembly described herein.

Abstract: Various embodiments described herein provide multi-projector (i.e., two or more) imaging apparatuses utilizing integrated illumination-aimer optics. Embodiments of the present disclosure minimize irreparable component offset to improve overall accuracy associated with the functioning of the apparatuses. Additionally, the integrated illumination-aimer optics enables embodiments disclosed herein to be provided in a significantly smaller form factor than conventional multi-projector imaging apparatuses. An example apparatus includes a near-field imaging lens and a far-field imaging lens, an integrated illumination-aimer optics positioned between the near-field imaging lens and the far-field imaging lens, a near-field illuminator source and a far-field illuminator source positioned for projecting via the integrated illumination-aimer optics, a near-field imaging sensor associated with the near-field imaging lens, a far-field imaging sensor associated with the far-field imaging lens, and an apparatus chassis to align the various components for operation.
