前記した従来技術によるデジタル画像の共有には、様々な問題がある。まず、スマートフォンなどの携帯端末をインターネット上のサーバに接続し、画像のダウンロードを行う場合は、当該携帯端末をネットワークに接続できる環境にないと、画像の閲覧ができないという問題がある。例えば、利用者が基地局からの電波が届かない地下室などにいる場合、携帯端末はネットワークに接続できないため、画像の閲覧ができなくなる。
本発明の一態様に係る画像閲覧システム1は、無線LANステーション204によるネットワークによって互いに接続される、大型表示装置201と、送信側携帯端末としての第一携帯端末101と、受信側携帯端末としての第二携帯端末102と、画像サーバ103とで構成される。
第1の実施の形態では、携帯端末101、102に記憶されている画像データが示す画像を、大型表示装置201を介して閲覧する際に、画像サーバ103にアップロードした画像の閲覧許可を与える端末のID(閲覧許可端末ID)を自動的に抽出するものであった。第2の実施の形態では、大型表示装置201を介さず、携帯端末101a、102a同士で画像データのやり取りを行う形態をとる。
第1および第2の実施の形態では、大型表示装置201を介して、あるいは他の携帯端末に直接、デジタル画像を他の利用者に公開した場合に、閲覧許可情報が閲覧可能な状態であれば、そのデジタル画像の恒久的な閲覧権限を他の利用者に与えるものであった。しかし、画像によっては、画像の所有者が見ている前での他の所有者への一時的な公開は許しても、所有者が見ていない場所での他の所有者への公開は、許したくない画像もある。第3の実施の形態に係る画像閲覧システム1bでは、このようなデジタル画像の取り扱いについて示す。
