In a photographing apparatus, an encoding part creates a code image from authentication information of the photographing apparatus. A photographing part takes a photograph of a connection code image displayed on a display part of another apparatus. A decoding part decodes the connection code image contained in the photograph taken by the photographing part to decode encoded connection information containing communication setup information, which has been encoded according to the authentication information of the photographing apparatus. A restoration part restores the communication setup information from the encoded connection information by using the authentication information of the photographing apparatus. A radio communication part communicates with the another apparatus by using the communication setup information restored by the restoration part.
