    Abstract: A directivity control system includes: a sound collection unit, configured to collect a sound; a display unit, configured to display a designation screen used to designate a directivity direction oriented from the sound collection unit to a first sound position; a directivity direction calculation unit, configured to calculate a horizontal angle and a vertical angle from the sound collection unit to the first sound position corresponding to the designated directivity direction in accordance with a designation of the directivity direction on the designation screen displayed by the display unit; and a control unit, configured to form directivity of the sound collected by the sound collection unit based on the horizontal angle and the vertical angle calculated by the directivity direction calculation unit.

    Abstract: In a sound source display system, an omnidirectional camera captures an image of a monitoring area. A microphone array collects a voice in the monitoring area. A monitoring monitor displays the image of an imaging area captured by the omnidirectional camera. A sound pressure calculator in a directivity control device calculates a sound pressure indicating a source of a sound in the image of the imaging area using voice data of the voice collected by the microphone array. An output controller in the directivity control device compares the sound pressure and threshold values (first threshold value, second threshold value), and causes sound image information in which the sound pressure is converted into visual information according to the result of comparison, to be displayed on the monitoring monitor so as to be superimposed on the image of the imaging area.
