Abstract

La présente invention concerne un appareil de fourniture d'image. Un appareil de fourniture d'image selon un mode de réalisation de la présente invention comprend : un haut-parleur interne ; un terminal de sortie de casque d'écoute ; et une unité de commande qui, lorsqu'un signal audio pour une sortie audio vers le haut-parleur interne et le terminal de sortie de casque d'écoute est entrée, commande l'appareil pour traiter le signal audio d'entrée et émettre le signal audio traité vers la haut-parleur interne et le terminal de sortie de casque d'écoute. Lorsqu'un écouteur est connecté au terminal de sortie de casque d'écoute, l'unité de commande commande l'appareil afin de produire un menu de sortie sonore comprenant un article indiquant une sortie audio vers le haut-parleur interne et le terminal de sortie de casque d'écoute. En conséquence, lorsqu'un écouteur est connecté au terminal de sortie de casque d'écoute, une fréquence audio peut être émise vers le haut-parleur interne et le terminal de sortie de casque d'écoute.
