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.
