Abstract

A generation unit generates the wireless network connection setting information from the first information based on the conversion rule. The encoding unit encodes the first information to generate a code image. A display unit displays the code image. An imaging unit captures the code image. A decoding unit decodes the code image captured by the imaging unit and acquires the first information. A second storage unit stores a conversion rule that is the same as the conversion rule stored in the storage unit. A second generation unit generates the wireless network connection setting information from the first information acquired by the decoding unit based on the conversion rule stored in the second storage unit. A communication unit connects to a wireless network using the wireless network connection setting information generated by the second generation unit.
