Information reproduction system

An information reproduction system comprising:

• image reading means for picking up and optically reading a code having a plurality of blocks arranged according to a predetermined block arrangement format, each of said blocks having at least a data pattern image corresponding to the contents of a block data formed by dividing the information data of the code by a given data volume and a header pattern image formed according to a block header indicating an address allocated to the block, so as to make each picked up image contain more than one blocks;
• block detection means for detecting each block from each code image picked up by said image reading means;
• address data acquisition means for acquiring the address data of each block detected by said block detection means;
• block data restoration means for restoring the block data of each block detected by said block detection means from the data pattern of the block;
• and
• information data reproduction means for combining the block data of the blocks of the codes restored by said block data restoration means according to the address data acquired by said address data acquisition means, wherein
• said address data acquisition means includes:
• plural addresses provisionally determining means for restoring and provisionally determining the address data of each of two or more than two blocks detected out of a picked up image by said block detection means;
• format information storage means for storing the format information relating to the address allocation for each of the blocks of the code to be read;
• and
• address determining means for determining the address of each of the blocks according to the address data of the two or more than two blocks provisionally determined by said plural address provisionally determining means and the format information stored in said format information storage means.
