1. An information reproducing method using a dot pattern, comprising:

  • scanning a medium as image data by a scanner such as a printed material on which is formed a dot pattern portion, which formed by arranging in accordance with a given rule dots generated by a dot code generating algorithm, in order to recognize various kinds of multimedia information;

    converting the image data of the dot pattern portion into code data; and

    reading multimedia information corresponding to the code data out of a storage unit to reproduce the multimedia information,wherein the dot pattern forms a lattice block by a horizontal line composed of successive equally spaced dots and a vertical line extending vertically from the horizontal line, the lattice block has a lattice area surrounded by lattice points, and an information dot that defines data is generated by the algorithm and arranged within the lattice area.
