Abstract

Selon l'invention, une unité centrale de traitement (CPU) de téléphone intelligent (60) recherche au moins un ou deux appareils photographiques numériques pouvant être connectés, et classe le ou les deux appareils photographiques numériques détectés dans au moins un ou deux groupes. Si une opération de sélection de groupe est réalisée, ce par quoi l'un du ou des deux groupes classés est sélectionné, une connexion est établie avec le ou les deux appareils photographiques numériques appartenant au groupe sélectionné. La CPU de téléphone intelligent (60) affiche, sur un dispositif de surveillance à cristaux liquides (LCD) (72) au moins une ou deux images réelles émises à partir de chacun du ou des deux appareils photographiques numériques connectés. La CPU de téléphone intelligent (60) change également le format d'affichage pour les images réelles chaque fois que l'état de connexion avec chaque appareil photographique numérique change, et change également celui-ci en réponse à une opération de sélection d'image qui sélectionne l'une des images réelles affichées.
