DIRECTIVITY CONTROL APPARATUS, DIRECTIVITY CONTROL METHOD, STORAGE MEDIUM AND DIRECTIVITY CONTROL SYSTEM

摘要

A directivity control apparatus controls a directivity of a sound collected by a sound collecting unit including a plurality of microphones. A beam forming unit forms a beam in a direction from the sound collecting unit toward a sound source corresponding to a position designated in an image on a display unit. A magnification setting unit sets a magnification for magnifying or demagnifying the image in the display according to an input. The beam forming unit also changes a size of the formed beam in accordance with the magnification set by the magnification setting unit.
