  • Patent number: 11995511
    Abstract: The present technology relates to image signal processing. One aspect of the present technology involves analyzing reference imagery gathered by a camera system to determine which parts of an image frame offer high probabilities of—relative to other image parts—containing decodable watermark data. Another aspect of the present technology whittles-down such determined image frame parts based on detected content (e.g., a cereal box) vs expected background within such determined image frame parts.

  • Patent number: 11954639
    Abstract: A method for detecting the usage of assets includes attaching a tracking device to each asset of a plurality of assets. An identifier associated with the asset is stored on a memory of the tracking device. After an asset has been used or is empty, the asset is physically grouped with other used or empty assets. Using the tracking devices, it is detected that an asset that the tracking device is attached to has been grouped with other assets. The tracking devices associated with the group of assets determine a manifest of asset identifiers for each asset in the group of used or empty assets. An asset tracking system determines that each asset corresponding to the identifiers in the manifest is used or empty.

  • Patent number: 11863897
    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.

  • Patent number: 10102463
    Abstract: In a two-dimensional code generation device (100), a white point determiner (111) determines a white point in an environment to output a two-dimensional code. A threshold acquirer (112) acquires a threshold of lightness used by a reading device for reading multiple cells in binary, the threshold being represented in a device-independent color space that is based on the white point determined by the white point determiner (111). A two-dimensional code generator (113) generates a two-dimensional code expressing information by a distribution pattern of multiple cell dots formed by coloring the multiple cells in a color of lightness equal to or higher than the threshold acquired by the threshold acquirer (112) and in a color of lightness lower than the threshold.

    Abstract: An array of pixels of a solid-state imaging sensor having a rolling shutter is sequentially exposed to capture images from an illuminated DPM target over successive frames for image capture by an imaging reader. The DPM target is illuminated at an elevated output power level for a fractional time period of a frame, and is not illuminated for at least a portion of a remaining time period of the frame for increased energy efficiency. Only a sub-array of the pixels is exposed during the fractional time period in which the DPM target is being illuminated at the elevated output power level.

  • Patent number: 9734376
    Abstract: This invention provides a system and method for decoding symbology that contains a respective data set using multiple image frames of the symbol, wherein at least some of those frames can have differing image parameters (for example orientation, lens zoom, aperture, etc.) so that combining the frames with an illustrative multiple image application allows the most-readable portions of each frame to be stitched together. And unlike prior systems which may select one “best” image, the illustrative system method allows this stitched image to form a complete, readable image of the underlying symbol. In an illustrative embodiment the system and method includes an imaging assembly that acquires multiple image frames of the symbol in which some of those image frames have discrete, differing image parameters from others of the frames.

  • Patent number: 9582703
    Abstract: A code reading device is equipped with a region extracting unit 2, which divides a photographed image of a bar code into a plurality of horizontal areas, and extracts readable regions from the horizontal areas respectively, and a region coupling unit 4, which couples the extracted regions to restore the whole bar code. Even if an unreadable portion occurs in a part of the bar code, a plurality of readable regions are extracted as parts of the barcode and those regions are coupled to restore a bar code the entirety of which can be read. Consequently, it is possible to accurately read a bar code having dirt or containment of illumination light partially.
