Abstract

L'appareil comprenant un objectif zoom (11), un moteur (12), un contacteur de téléobjectif (13) qui est actionné pour faire que le moteur (12) entraîne l'objectif de manière à augmenter sa distance focale, un contacteur de grand angle (14) qui est actionné pour faire que le moteur (12) entraîne l'objectif de manière à diminuer sa distance focale, un moyen de commande est prévu pour modifier la vitesse de changement de plan lorsqu'une condition prédéterminée est remplie pendant l'opération de changement de plan lorsque l'un des contacteurs de téléobjectif (13) ou de grand angle (14) est actionné.
