    摘要: Disclosed herein is a barcode reading system that includes an image decoding system, a communication interface, and an image sensor system package. The image decoding system may include a processor, memory, and a decoder stored in the memory. The image sensor system package may be coupled to the image decoding system via the communication interface. The image sensor system package may include a photo sensor array and pre-processing circuitry. The photo sensor array may be configured to capture image frames at a first speed. The pre-processing circuitry may be configured to perform one or more operations on the image frames captured by the photo sensor array. The pre-processing circuitry may be additionally configured to effect transfer of at least some of the image frames to the image decoding system via the communication interface at a second speed. The first speed may be greater than the second speed.

    摘要: This disclosure describes methods and systems for using a barcode reader to read multiple barcodes positioned on an object. The barcode reader attempts to locate a first priority barcode within an image using first priority information. The priority information may define a region of interest within the image. The barcode reader may search only the region of interest for the first priority barcode. The priority information may define one or more characteristics of the first priority barcode. Based on the results of attempting to locate the first priority barcode, the barcode reader determines whether to attempt to locate a second priority barcode within the image. The barcode reader may discard the image if the barcode reader fails to locate the first priority barcode or the results of attempting to locate the first priority barcode indicate that the image is unlikely to contain a decodable second priority barcode.

    摘要: This patent specification describes a barcode-reading enhancement accessory for a mobile device having a barcode-reading capability. The accessory may include an outer case and an inner carriage. A mobile device is encased in the inner carriage, and the combination of the inner carriage and the mobile device may be accommodated in the outer case. The inner carriage is configured to accommodate a mobile device of a particular size such that a mobile device of a different size may be accommodated in the outer case using a different inner carriage. The accessory may also include an optic system to fold an optical path of a field of illumination of a light source of the mobile device and/or a field of view of a camera of the mobile device.

    摘要: An application on a mobile device may include a barcode decoder. The application may be configured to download a configuration file. The configuration file may include an enterprise identifier that is uniquely associated with an enterprise. The application may additionally be configured to obtain a license key for the barcode decoder. The license key may be based on the enterprise identifier. The application may additionally be configured to transition the barcode decoder from an inactive state to an active state conditional upon verifying that the license key is based on the enterprise identifier.

    摘要: A method for glare reduction may be implemented by a graphical code reader. The graphical code reader includes an optic system, a plurality of light sources, and a control system. The control system is configured to determine that glare is present in an image captured by the optic system by identifying reflection from at least one of the plurality of light sources. The control system may take a corrective action to reduce the glare in subsequent images. The control system may be configured to take a first corrective action if a diffraction pattern is present at a periphery of the glare, and take a second corrective action if a diffraction pattern is not present at the periphery of the glare.
