| Abstract(in English) | Recently, a lot of QR codes are shown in advertising booklets and Web pages to lead users to a particular site. In order to improve the visibility of QR codes, design QR codes have been invented. Some intentionally modify several bits of original QR code within the possible error correction capability, and the others change the pad codeword to produce a specific designed image on the QR code. However, the exploitation of error correction capability for design degrades the readability of design QR codes, and the possible area in which the designed image is embedded is restricted due to the standardized structure of QR code. The main restriction is the systematic encoding of Reed-Solomon code(RS). In this study, we focus on non-systematic encoding of Reed-Solomon code, and reduce the restriction. As the result,we can freely select the design area in a QR code and can embed a designed image without sacrificing the error correction capability of RS code. It is noteworthy that our designed QR code can be read by the QR code readers equipped in mobile phones. |
