Summary:PROBLEM TO BE SOLVED: To identify a portion corresponding to the display screen of an image included in another image, by a method less likely to be sensed with human eyes.SOLUTION: A storage unit 111 stores first image information displayed on a display screen. A generation unit 112 generates embedded information which varies timewise. A superimposition unit 113 superimposes the embedded information on at least an image portion corresponding to the end of the display screen out of the first image information and thereby generates second image information having the embedded information superimposed thereon. Then, an output unit 114 outputs the second image information. 【課題】人の目に知覚されにくい方法で、映像に含まれる別の映像の表示画面に対応する部分を特定する。【解決手段】記憶部１１１は、表示画面に表示される第１の映像情報を記憶する。生成部１１２は、時間的に変化する埋め込み情報を生成する。重畳部１１３は、第１の映像情報の中の少なくとも表示画面の端部に対応する映像部分に、埋め込み情報を重畳することで、埋め込み情報が重畳された第２の映像情報を生成する。そして、出力部１１４は、第２の映像情報を出力する。【選択図】図１
