• the unit cell patterns 510 are constructed by assigning X coordinate values to respective cells as shown in FIG.8, assigning Y coordinate values to respective cells as shown in FIG. 12, and combining the X coordinate values with the Y coordinate values in the same cell position.
• the resulting unit cell patterns 510 are shown in FIG. 14.
• the unit cell patterns shown in FIG. 5 corresponds to an example of applying the order of assigning/combining binary data shown in FIG. 11 to both X and Y coordinates
• the unit cell patterns shown in FIG. 14 corresponds to an example of applying/combining the orders of assigning/ combining the binary data shown in FIGs. 7 and 11 to the X and Y coordinates, respectively.
• the unit cell patterns shown in FIGs. 5 and 14 have the same absolute coordinate value of corresponding unit cell patterns.
• the second cells 502 constituting the direction flag 503 must be arranged in such a manner that the direction flag itself has a directive feature. At least three second cells must be used to this end. If fewer second cells are used, at least two directive features exist no matter how the second cells are arranged. It is to be noted that, if the direction flag 503 is not used to sense rotation but just to correct errors, two or more cells are enough to constitute the direction flag. Furthermore, if the direction flag 503 is used just to differentiate adjacent unit cell patterns from one another, only a single second cell 502 may constitute the direction flag.
• the second cells 502 constituting the direction flag 503 contain no information or information coded and displayed in a manner different from that of the first cells 101.
• FIG. 15 they have no directive feature and are useless. Such an arrangement must be excluded.
• the restored direction flag has the shape of +, it has been rotated by 90 clockwise.
• the shape of + corresponds to 180 rotation
• the shape of + corresponds to 90 counterclockwise rotation.
• the direction flag shown in (a) of FIG. 16 has undergone no rotation
• the direction flag shown in (b) of FIG. 16 when restored gives the shape of +, which corresponds to 90 clockwise rotation
• the direction flag shown in (c) of FIG. 16 when restored gives the shape of +, which corresponds to 180 rotation.
• Such a relationship is used to determine the angle of rotation of the product (e.g. paper) and to rotate the matrix of cells on the coordinate window accordingly.
• the second cells of the direction flag for identifying the window display two-bit binary data that has been coded in a manner different from that of the first cells.
• the two-bit values correspond to the error correcting code of the X and Y coordinates, respectively.
• the error correcting codes for the X and Y coordinates are separately operated in a similar manner. Therefore, the error correcting code will be described with reference to only the X coordinately for clarity.
• a single 4x4 window contains 13 bits of information regarding the X coordinate, but it must have at least 4 bits of redundancy for 2-bit error correction.
• Ic Ic algorithm for block codes i.e. RS (Reed-Solomon) code
• RS Random-Solomon code
• Respective second cells are coded based on representation different from that of the first cells so that the second cells can contain 2-bit information. Even if four second cells are used, the position of patterns is calculated in the same manner, except that the number of the first cells in the window is reduced by one. Then, the RS coding, which is one of error correcting codes, is used to calculate (encode) an error correcting code regarding all or some of information in the data cells and to display the coding result on the direction flag cells. If the window is not correctly read, the error correcting code cannot function properly. However, it is also possible to correct errors by calculating the position according to the original position calculating method and conducting RS decoding. This, however, may not provide correct restoration because an estimated codeword, not the original RS-encoded codeword, is subjected to RS decoding.
