Abstract:
An information reproduction system comprising:image inputting means for imaging a dot code which is optically readably recorded on an information recording medium, the dot code comprising a plurality of blocks arranged adjacent to each other, each of the blocks comprising (i) a plurality of data dots arranged in accordance with contents of multimedia information to be reproduced, (ii) a marker located to have a predetermined positional relationship with the data dots, the marker being used to determine reference read points for use in reading the data dots, respectively, and (iii) address dots representing an address of each of the blocks;restoring means for restoring an image obtained by the image inputting means to data of the multimedia information, said restoring means including address dot reading means for detecting the address dots representing the address of each of the blocks from the image obtained by the image inputting means, and for then reading out the address of each of the blocks; anddata reproducing means for reproducing the data obtained by the restoring means as original multimedia information;wherein the information reproduction system further comprises:a checking section for checking whether or not a numeral value of an address read out by the address dot reading means is within a numeric range of addresses to be handled by the information reproduction system; andaddress determining means for determining that the address read out by the address dot reading means is a correct address when the checking section confirms that the numeral value of the read address is within the numeric range of addresses to be handled by the information reproduction system.
