  • Patent number: 8500026
    Abstract: A grayscale two-dimensional barcode may be converted to a two-dimensional color barcode. The color barcode includes a set of sub-regions, and the cells in each sub-region exhibits a color pattern that corresponds to pattern of binary, grayscale cells. The two-dimensional color barcode may be decoded by comparing the pattern for each sub-region to a known grayscale pattern. The two-dimensional color barcode may be used for error correction by first decoding the barcode in grayscale form based on the luminance without reference to color, then decoding the barcode based on its color and comparing the results.

  • Publication number: 20130186957
    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.

  • Patent number: 8453934
    Abstract: A technique and a light emitting device that can smoothly read out data while tracking a position of the light emitting device (an object). The light emitting device expresses data with “a change in the change of a color (switching of changes)”. The light emitting device specifies an object and the position thereof with a first primary change and thereafter expresses data with, so to speak, a secondary change (switching of the primary change). The primary change means that G and B alternately turn on (indicated by G*B) and so on. The secondary change means a change from the condition (G*B), in which G and B alternately turn on, to the condition (B*R) in which B and R alternately turn on. Thus, since data is expressed by the change of color condition changes, it is easier to freely express data while the position of an object is specified.

  • Publication number: 20090314838
    Abstract: It is possible to linearly arrange cells and indicate particular data in the order of colors of respective sells. A code system uses an optical symbol decoding method capable of reading the color arrangement if the arrangement continuity and the linear shape are maintained. The data expression method may be other than “the order of colors.” For example, it is possible to employ a method for allocating a numeric value to each of the colors by one-to-one correspondence (R=0, B=1, etc.), a method for allocating data by a color transition (“CM”=“MY”=“YC”=0, “CY”=“YM”=“MC”=1, etc.), a method for allocating data for a combination of colors, and the like.

  • Patent number: 7611059
    Abstract: On a display window that displays code patterns that are read at a time, a code reading device allows the code pattern that is successfully decoded to be visually confirmed with ease. In a handy terminal, when an image scanner reads code patterns at a time in response to a trigger operation, a CPU performs decoding processes for each code pattern and determines whether the decoding processes have been successfully completed or not based on the decoding results so as to display an identifying mark indicating the determination result in association with the image of each code pattern.

  • Publication number: 20090194596
    Abstract: It is possible to provide a code using an optical symbol which can be read with a high accuracy even under an environment of a low printing accuracy including printing on an article which can be easily deformed. Cells are arranged in a linear shape and particular data is indicated by a state of element in each of the cells (whether the element is colored). Especially a particular color is fixed to each of the elements and it is possible to use the two states whether the color is attached or note. This state can express the data. Accordingly, it is possible to realize a code system capable of ready data if the element sequence continuity and the form (topology) as the linear state are maintained.

  • Patent number: 7460278
    Abstract: A 3-D dot code is embedded in a printed medium using an embedder that embeds data directly into the halftone dots of a selected file that is ready for printing. An extractor extracts the embedded bits by scanning the printed medium and then interprets the embedded data. A bleed-through elimination module in the extractor is able to eliminate adverse affects on the scanned input of the embedded data caused by bleed-through from the print on the opposite side of the page. The extractor may also include a module that compensates for a misaligned scanned input by automatically detecting the rotation and translation, and then registering the image so that the upper-left corner is located in a certain position. This operation expedites subsequent data retrieval, in which data is read by block matching.
