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： Disclosed herein is an attachment for a smartphone. The smartphone may include i) a camera with an image sensor and a focusing lens located on a back side of the smartphone for capturing an image of a target area; and ii) a white light source on the back side of the smartphone. The attachment may include a targeting optic system. When the attachment is secured to the back side of the smartphone, the targeting optic system may receive illumination emitted by the white light source and direct the illumination towards the target area from a location that is not directly in front of the camera's image sensor. The location may be farther from the focusing lens than the white light source when measured parallel to the back side of the smartphone. The attachment may also direct the illumination into the target area via the targeting optic system.

摘要： A barcode reader may include an image sensor array, an optic system, an image buffer, and a plurality of pre-processing circuits implemented in hardware. The optic system may be configured to focus an image of a barcode onto the image sensor array. The plurality of pre-processing circuits may collectively implement a plurality of different image processing functions. Each pre-processing circuit may be configured to receive as input an image frame from the image sensor array or an image data record from the image buffer. The image data record may be derived from the image frame. Each pre-processing circuit may also be configured to perform an image processing function with respect to the image frame or the image data record, thereby generating a new image data record. A decoder may use at least one image data record to decode the 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： 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 an attachment for a mobile device. The attachment may have an attachment feature designed to be attached to a mobile device such as a smartphone, tablet, or smartphone/tablet with a camera. The attachment may also include an optics system and/or an illumination system that cooperates with the camera to facilitate the capture of decodable barcodes. The illumination system may include a targeting illumination system that facilitates proper positioning of the article and/or an exposure illumination system that helps illuminate the article during capture. The optics system may include a lens that modifies the depth of field and/or the size of the field of view of the camera, an aperture that helps define the field of view, a filter that prevents light of undesired wavelengths from reaching the camera, and/or a mirror that redirects the camera's optical pathway.

摘要： A barcode reader is disclosed. The barcode reader may include a semiconductor package and an optic system. The semiconductor package may include a plurality of silicon dies stacked vertically and interconnected by through-silicon vias (TSVs) or wires. A first die positioned on top of the plurality of stacked silicon dies includes a photo sensor array and image read-out circuitry. The image read-out circuitry is coupled to the photo sensor array and configured to generate a frame of image data, wherein the frame of image data is a sequence of values, each value representing an intensity of illumination focused on one of the photo sensors. The optic system is configured to focus an image of a barcode on the photo sensor array. The optic system includes a lens assembly and a mirror. The mirror folds an optical path behind the lens assembly onto the array of photo sensors.

摘要： Described herein is a barcode-reading system for a mobile device that may include an optic system with a reflective surface for folding a field of view of a camera of the mobile device towards a target area positioned at a top side of the mobile device, a reflective surface for folding a field of illumination of a white light source of the mobile device towards the target area, and a target-generating mechanism for narrowing the field of illumination of the white light source along a first direction such that the field of illumination of the white light source has a divergence angle in the first direction that is approximately the same as a divergence angle of the field of view of the camera in the first direction.

摘要： A barcode reader may perform image processing functions to generate distinct image data records from the frame of image data of a barcode, select an image data record from the distinct image data records and decode the selected image data record. Each image data record may be generated by applying a distinct image processing function to the frame of image data. The barcode reader may capture multiple frames of image data in sequence based on image capture parameters. At least one of the multiple frames of image data may be captured with a distinct parameter value. The image capture parameters may include an exposure setting, a gain setting, a resolution setting, and/or an illumination setting.
