    Abstract: A roller laser encoding apparatus includes a barcode formed on a curved surface to form a curved barcode surface wherein the barcode is a sequence of different color laser reflectivity. When a laser transmitter emits a laser beam toward the curved barcode surface, the laser beam is reflected by the curved barcode surface to form a reflected laser beam. After the reflected laser beam is received by a laser receiver as a light signal, the optoelectronic converter converts the light signal of the reflected laser beam into a voltage signal. After the curved barcode surface is rotated in one revolution, an encoding processor collects the voltage signals from the optoelectronic converter in sequent and generates a sequence of voltage value in response to the sequence of different color laser reflectivity of the curved barcode surface so as to output a decoding signal of the curved barcode surface.

    Abstract: The aim is to reduce the influence of the filming environment of an image that represents a two-dimensional code when determining a color that has been added to a cell in the two-dimensional code. Disclosed is a two-dimensional code (100) in which a mark is added to each cell group in an information color or a combination color that is correlated with the information indicated by the cell group, and the mark for each cell (C) in the cell group is added in a specified coordinate color within a component domain from among a component model representing the distribution of color components, that is disposed in a positional relationship void of mutual interference.

    Abstract: A decodable indicia reading system can be provided for use in locating and decoding a bar code symbol represented within a frame of image data. The system can comprise a central processing unit (CPU), a memory communicatively coupled to the CPU, and two or more image sensors communicatively coupled to the CPU or to the memory. The system can be configured to select an image sensor for indicia reading by cycling through available image sensors to detect an image sensor suitable for an attempted indicia reading operation by comparing a measured parameter value to a pre-defined sensor-specific threshold value. The system can be further configured to select the first suitable or the best suitable image sensor for the attempted decodable indicia reading operation based upon the comparison result. The system can be further configured to notify the system operator which image sensor has been selected. The system can be further configured to obtain a decodable indicia image by the selected image sensor.

  • Patent number: 8584953
    Abstract: A computing device and method for reading a barcode captured with a color image sensor is disclosed. The barcode can have features and background that have equal brightness and a substantially low chromacity deviation such that the barcode could not be easily perceptible and decoded with known greyscale decoding techniques. The method for reading the barcode includes receiving color image values for each pixel of a captured image of a target barcode from a color image sensor, determining chrominance values for each pixel from the color image values, detecting edges based on the chrominance values to generate an edge-detected image that is provided to a greyscale barcode decoder to decode the information in the target barcode. The chrominance values can be based on the blue and red difference components from the YUV image format, and the U and V values can be combined using color temperature information.

  • Patent number: 8534560
    Abstract: Disclosed is a technology that specifies each of a plurality of two-dimensional codes in an image and reduces the processing time for judging color in each cell region in each specified two-dimensional code. Based on edge images generated from obtained images, candidate regions among these edge images are extracted, a judgment is made about whether or not a characteristic pattern is included in each of the corresponding regions in the original images that correspond to these extracted candidate regions, and then the two-dimensional code regions are detected from among the original images. The color is judged both for each pixel group that comprises each row of that region and for each pixel cell, in pixel array order. If it is determined that a certain number or more pixels in each row that corresponds to each cell region are included in the color judgment region, color judgment is omitted for the remaining pixels in that row.
