A method and apparatus for decoding a two-dimensional bar code symbol using a charge-coupled device (CCD) camera, charge-modulation device (CMD) camera, or other bar code reading device such as a hand-held reader, light pen or wand, scan mouse, or stationary laser scanner. The CCD/CMD
A system for reading and decoding a two-dimensional bar code symbol having rows of bar-coded information in which data is represented in each row by a plurality of codewords, each row including a predetermined control codeword, the codewords being formed of a plurality of modules, comprising: a two-
A system for reading and decoding a two-dimensional bar code symbol having rows of bar-coded information in which data is represented in each row by a plurality of codewords, each row including a predetermined control codeword, the codewords being formed of a plurality of modules, comprising: a two-dimensional imaging camera for optically imaging the bar code symbol to obtain lines of image data corresponding to a field of view including the bar code symbol; a memory for storing the lines of image data; means for determining an orientation of the two-dimensional bar code symbol in the field of view by locating control codewords in at least two positions in the image data; means for determining a sequence of lines passing through the rows of the bar code symbol in the image data from the orientation determined from the positions of the control codewords; and means for scanning the two-dimensional bar code symbol in the image data along the sequence of lines line to read the codewords.
