    Abstract: An approach to the design of the set of filters which allows for the collection of a larger portion of the optical signal while still distinguishing the presence of the various fluorophores is described. In some embodiments, the filter sets of the invention each block a smaller portion of the spectrum, allowing for a larger portion of the emitted light to be detected. The combined information from the light passing through two or more of the filters is then used to determine the presence of a given fluorophore. The filter sets of the invention can be particularly useful in integrated devices in which the light from a single molecule reaction in a small reaction region is directed to a detector or to a specific portion of a detector.

To read and decode a three-dimensional bar-code, a light-field camera is used to capture the whole three-dimensional structure and the focus levels are then determined for a predetermined number of vertical levels. Adding color adds another degree of freedom (dimension) in the number and difficulty of encoding and decoding the three-dimensional bar-codes. These bar-codes cannot be simply made or copied, providing a level of security thereby.

  • Patent number: 8978984
    Abstract: A terminal for decoding decodable indicia includes a plenoptic imaging subsystem comprising an image sensor array and plenoptic imaging optics operable to project a plenoptic image of a space containing the decodable indicia onto the image sensor array, a hand held housing encapsulating a least a portion of the plenoptic imaging subsystem, a trigger for initiating operation of the plenoptic imaging subsystem to obtain plenoptic image data of the decodable indicia, and an illumination source for projecting illumination onto the decodable indicia; an aimer for projecting an aimer pattern onto the decodable indicia. The terminal is operable, responsive to detecting that the trigger has been actuated by an operator, to obtain plenoptic image data from the image sensor array, to obtain first rendered image data based on at least a portion of the plenoptic image data, and to attempt to decode the decodable indicia represented in the rendered image data.

  • Patent number: 8978985
    Abstract: The invention features an image reader and a corresponding method for capturing a sharp distortion free image of a target, such as a one or two-dimensional bar code. In one embodiment, the image reader comprises a two-dimensional CMOS based image sensor array, a timing module, an illumination module, and a control module. The time during which the target is illuminated is referred to as the illumination period. The capture of the image by the image sensor array is driven by the timing module that, in one embodiment, is able to simultaneously expose substantially all of the pixels in the array. The time during which the pixels are collectively activated to photo-convert incident light into charge defines the exposure period for the sensor array. In one embodiment, at least a portion of the exposure period occurs during the illumination period.

    Abstract: A method of imaging a target object with an imaging reader. The method includes the following: (1) detecting light from the target object through a lens arrangement with an image sensor to generate light-field data; (2) generating a stream of image data including image data representing an expected in-focus image of the target object, and (3) processing the expected in-focus image of the target object to decode a barcode on the target object. The image sensor includes an array of photosensitive elements and an array of microlenses that overlays the array of photosensitive elements located at a focus plane of the microlens.

  • Patent number: 8955752
    Abstract: An automatic testing method applied to an automatic testing system for testing a barcode identification apparatus is described. In the method, a test host is utilized to generate a barcode pattern automatically, so as to display the barcode pattern through a barcode revealing apparatus. The barcode identification apparatus reads and resolves the barcode pattern to retrieve an identification result. The identification result is returned to the test host. The test host compares the barcode information carried by the barcode pattern and the identification result, and generates a test result. The test host repetitively generates the barcode pattern for a barcode identification apparatus carried the barcode pattern and the identification result, and then generates a test result. Through the test host repeatedly generates the barcode pattern and records the corresponding test result, manual operation is not required to obtain testing data for being analyzed.

  • Patent number: 8950674
    Abstract: An imaging lens assembly captures return light from a target, and projects the captured light onto a solid-state imager during electro-optical reading of the target. One plastic lens and one glass lens, together having a relatively low negative optical power, are situated at one side of an aperture stop. Another plastic lens and another glass lens, together having a relatively high positive optical power, are situated at the opposite side of the aperture stop. An aperture extends along an optical axis through the opposite sides. Each plastic lens is configured with opposite aspheric nearly concentric surfaces to widen and flatten the field of view of the imager, and to reduce sensitivity to manufacturing and assembly tolerances. A holder holds the lenses and the aperture stop in spaced relation along the optical axis relative to the imager.

    Abstract: A barcode reading method and a barcode reading device are provided. An image sensor is utilized to capture an image of a barcode via an optical lens, and then a triangulation method and an ideal lens imagining method are collocated to calculate the digital image so as to produce an optimum image distance. A distance between the image sensor and the optical lens is then adjusted in accordance with the optimum image distance, so that the barcode can be immediately and clearly imaged on the image sensor.

  • Publication number: 20150014417
    Abstract: Described herein are systems and methods employing embedded barcodes to convey supplemental information about an image, for example a motion picture. In some systems the barcodes may be subliminal because they are spliced, physically or digitally, into a movie frame shown too briefly to be consciously detectable to the human eye, but still detectable by camera sensors. Other described systems may display the barcodes in infrared or ultraviolet light, which is outside of the visible spectrum of light perceived by the human eye, but still detectable by camera sensors.

  • Patent number: 8919653
    Abstract: Disclosed are systems and methods for unassisted (i.e., customer controlled) exception handling in an automated data reader having a read zone. A first imager obtains a first image of an exception item in response to an exception generated in a read zone. An exception handling station receives the exception item, and a second imager located at the exception handling station obtains a second image of the exception item. An image processor receives the images, identities visual object recognition features from each image, and compares the features to determine whether the first and second images represent the same exception item. If so, the exception is cleared, and the item is added to a transaction list.

  • Patent number: 8915443
    Abstract: A barcode decoding method includes obtaining a plurality of scanning lines defining a second set of scanning lines which also comprises a predetermined scanning line. Each scanning line has a first set of pixels, each identified by a first and by a second index. The pixels that are part of the second set of scanning lines define a third set of pixels and, from the pixels of the third set of pixels, it is possible to select a fourth set of pixels to construct an oversampled profile of the barcode, ordering intensity values calculated from the intensity values of the pixels of the fourth set. The pixels of the fourth set include pixels of the predetermined scanning line and further pixels of the third set that do not belong to the predetermined scanning line, to obtain a subpixel resolution that is able to decode the barcode.
