Abstract

Lorsqu'un dispositif d'imagerie fonctionne dans un premier mode de fonctionnement, une unité de commande détermine si le dispositif d'imagerie peut ou non continuer à fonctionner dans le premier mode de fonctionnement, sur la base d'une première capacité résiduelle de batterie. Lorsque l'unité de commande détermine que le dispositif d'imagerie ne peut pas continuer à fonctionner dans le premier mode de fonctionnement, elle fait passer le dispositif d'imagerie du premier mode de fonctionnement à un second mode de fonctionnement. La première capacité résiduelle de batterie est une capacité résiduelle pouvant être utilisée dans le premier mode de fonctionnement, mais ne pouvant pas être utilisée dans le second mode de fonctionnement.
