Abstract:
1. A photographing apparatus comprising: an encoding part configured to create a code image from first authentication information of said photographing apparatus; a display part configured to display at least one of an image of a photographing subject, an operation menu and said code image; a photographing part configured to take a photograph of a connection code image displayed on a display part of another apparatus different from said photographing apparatus; a decoding part configured to decode said connection code image contained in the photograph taken by said photographing part to decode encoded connection information containing communication setup information, which is used in establishing a radio communication and has been encoded according to said authentication information of said photographing apparatus; a restoration part configured to restore said communication setup information from said encoded connection information, which has been decoded by said decoding part, by using the first authentication information of said photographing apparatus; and a radio communication part configured to communicate with said another apparatus by using the communication setup information restored by said restoration part, wherein the photographing apparatus further comprises a code image presenting part configured to present said code image to said another apparatus by causing the display part to display said code image so that said another apparatus acquires the first authentication information of said photographing apparatus by taking a photograph of said code image displayed on said display part of said photographing apparatus and decoding said code image from the photograph of said code image, and wherein the decoding part decodes a code image presented by said another apparatus in order to acquire communication setup information of said another apparatus and second authentication information of said another apparatus, the second authentication information being acquired from new authentication information, which is created by said another apparatus based on the first authentication information and the second authentication information, and wherein said radio communication part establishes a communication with said another apparatus using the acquired communication setup information of said another apparatus and the acquired second authentication information of said another apparatus.
