PROBLEM TO BE SOLVED: To track a subject with high accuracy even when an optical tag cannot be recognized.SOLUTION: A light-emitting tag 10 is mounted on the wrist of a user or the like. In the light-emitting tag 10, a CPU 13 emits a visible light including a color pattern corresponding to first identification information 11a from a light-emitting part 14. In an imaging apparatus 20, a CPU 27 receives, by an imaging part 22, the visible light that is emitted from the light-emitting part 14 of the optical tag 10, acquires the first identification information included in the visible light, and registers the acquired first identification information and second identification information 24a that is different from the first identification information 11a and is information for image recognition, while associating them with each other. When photographing a moving picture, a position of a subject is identified based on the first identification information 11a and/or the second identification information 24a, and the moving picture is photographed while tracking the subject.SELECTED DRAWING: Figure 2 【課題】光タグが認識できなくなった場合でも、高精度で被写体を追尾する。【解決手段】発光タグ１０は、ユーザーの手首等に装着される。発光タグ１０において、ＣＰＵ１３は、第１の識別情報１１ａに相当する色パターンを含む可視光を発光部１４から発光する。撮像装置２０において、ＣＰＵ２７は、光タグ１０の発光部１４から発光される可視光を撮像部２２で受光し、当該可視光に含まれる第１の識別情報を取得し、該取得した第１の識別情報と、第１の識別情報１１ａとは異なる画像認識のための情報である第２の識別情報２４ａを関連付けて登録する。動画撮影時には、第１の識別情報１１ａ、及び／又は第２の識別情報１１ａに基づいて被写体の位置を特定し、被写体を追尾しながら動画撮影を行う。【選択図】図２
