  • Apparatus for Reading a Color Symbol
    Publication number: 20080246967
    Abstract: The present invention provides an apparatus for reading a color symbol, which comprises a matrix of color filters arranged in front of a detector. Light received from the filters of some colors is used to locate the color symbol, while light received from all the filters is used to read and decode the located symbol. Preferably, the filters used for locating the symbol are of the colors to which the detector is most sensitive. Preferably, the filters for locating the symbol are dominant in number.
    Type: Application

  • Method of decoding a symbol with a low contrast
    Patent number: 7311262
    Abstract: A method for encoding a symbol such as a barcode with a finder of a known pattern, comprises steps of determining a potential point on the finder edge and tracing and verifying a path representing the finder edge by checking the color of each point on the path against a threshold. The threshold is preferably reevaluated at least every several pixel movements along the path. The method may decode the barcode directly from the gray image displayed on a LCD screen without a need of a whole characterized image.

  • Method of decoding barcode symbols and the like using multiple scanning lines
    Publication number: 20060060654
    Abstract: The present invention provides a method of encoding a barcode, in which the barcode is scanned at multiple scanning lines along plural length portions to determine potential locations where the bars probably exist. For each potential length, data obtained at all the scanning lines is synthesized to determine the validity of the location. The plural length portions are then combined to ascertain the information.
