摘要

The invention is characterized in that a protection-encoding pattern is obtained based on an error correction codeword, that a protection-encoded code block is obtained by protection-encoding using the protection-encoding pattern a code block having a data codeword, and that the 2D barcode is generated based on the protection-encoded code block.
