Abstract

　Un dispositif de commande de directivité commande la directivité d'un son détecté par une unité de prise de son comprenant une pluralité de microphones. Une unité de formation de faisceau forme un faisceau dans une direction, de l'unité de prise de son à une source sonore, correspondant à une position désignée sur une image d'une unité d'affichage. Une unité de définition d'agrandissement définit l'agrandissement nécessaire pour agrandir ou rétrécir l'image sur l'unité d'affichage en réponse à une entrée. L'unité de formation de faisceau change également la taille du faisceau formé d'après l'agrandissement défini par l'unité de définition d'agrandissement.
