Abstract: A directivity control apparatus controls a directivity of a sound collected by a first sound collecting unit including a plurality of microphones. The directivity control apparatus includes a directivity forming unit, configured to form a directivity of the sound in a direction toward a monitoring target corresponding to a first designated position in an image displayed on a display unit, and an information obtaining unit, configured to obtain information on a second designated position in the image displayed on the display unit, designated in accordance with a movement of the monitoring target. The directivity forming unit is configured to change the directivity of the sound toward the monitoring target corresponding to the second designated position by referring to the information on the second designated position obtained by the information obtaining unit.

Abstract: A recorder receives designation of a video which is desired to be reproduced from a user. If designation of one or more designated locations where sound is emphasized on a screen of a display which displays the video is received by the recorder from the user via an operation unit during reproduction or temporary stopping of the video, a signal processing unit performs an emphasis process on audio data, that is, the signal processing unit emphasizes audio data in directions directed toward positions corresponding to the designated locations from a microphone array by using audio data recorded in the recorder. A reproducing device reproduces the emphasis-processed audio data and video data in synchronization with each other.

Abstract: 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.
