Le dispositif d'imagerie d'intervalle 2 comprend : des unités d'imagerie 11, 12 capables de capturer une image selon une pluralité de modes de capture d'image ; des capteurs de mouvement 13, 14 pour détecter le mouvement du dispositif d'imagerie d'intervalle ; une unité de détermination de mouvement 24a pour déterminer la présence d'un mouvement à partir des résultats de détection des capteurs de mouvement ; une unité de génération de synchronisation 24b pour générer à des intervalles prescrits un signal déclencheur pour les unités d'imagerie pour qu'elles capturent une image ; et une unité de commande de capture d'image 24c pour commander les unités d'imagerie et l'unité de génération de synchronisation selon le résultat de détermination de l'unité de détermination de mouvement. Les unités d'imagerie sont pourvues, par exemple, d'un mode standard pour capturer une image sous un angle de vue standard et d'un mode grand angle pour capturer une image sous un grand angle de vue, et l'unité de commande de capture d'image commande les unités d'imagerie afin de capturer une image dans le mode standard lorsqu'il y a un mouvement (état de mouvement) et de capturer une image dans le mode grand angle lorsqu'il n'y a pas de mouvement (état stationnaire).
