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

摘要

A directivity control apparatus controls the directivity of sounds collected by a first sound collection unit including a plurality of microphones. A directivity formation unit forms the directivity of the sounds in a direction extending from the first sound collection unit toward a monitoring target corresponding to a first designated position on an image displayed on a display unit. An information acquisition unit acquires information related to a second designated position on the image displayed on the display unit, said second designated position being designated in accordance with a movement of the monitoring target. The directivity formation unit changes, by use of the acquired information related to the second designated position, the directivity of the sounds to a direction extending toward the monitoring target corresponding to the second designated position.
