Abstract

　埋め込むべき情報を有する図形パターンを画像データに埋め込む電子透かし埋め込み装置であって、前記図形パターン埋め込み部が前記図形パターンを画像データに埋め込む際、前記画像データにおける、前記図形パターンが有する信号的特徴に係る部分の近傍画素を変更する近傍画素変更部と、前記近傍画素変更部による、前記画像データにおける、前記図形パターンが有する信号的特徴に係る部分の近傍画素の変更を伴うようにして前記図形パターンを画像データに埋め込む図形パターン埋め込み部とを備え、前記近傍画素変更部は、前記図形パターンが埋め込まれた画像データに対する画像拡大処理或いは画像縮小処理がなされた場合であっても前記図形パターンが有する信号的特徴が維持され得る態様で、前記画像データにおける、前記図形パターンが有する信号的特徴に係る部分の近傍画素を変更する構成とされてなる。
