Abstract

Le domaine d'application de la présente invention est la détection infrarouge. L'invention concerne un appareil de détermination et un procédé de détermination. Dans l'état de la technique, quand une image thermique infrarouge affichée comprend plusieurs régions à analyser, des ombres apparaissent sur l'image thermique d'un objet photographié, ce qui affecte l'observation et le jugement de l'utilisateur; quand plusieurs régions à analyser sont affichées sans différenciation, l'utilisateur ne peut pas reconnaître visuellement une partie qui est accentuée. L'appareil de détermination comprend : une partie analyse servant à obtenir un résultat de comparaison relatif à des données d'image thermique; une partie comparaison servant à comparer le résultat d'analyse à une valeur spécifiée; et une partie détermination servant à déterminer un état de présentation d'une identification rapide et/ou de la région à analyser qui sont associées aux données d'image thermique. De cette manière, le problème est résolu.
