Directivity control system, directivity control method, sound collection system and sound collection control method

摘要

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.

1. A directivity control system comprising:
a sound collector, which in operation, collects a sound; a display apparatus, which in operation, displays a setting screen of a directivity direction oriented from the sound collector to a prearranged second sound position in one or more sound collection areas or a designation screen of a directivity direction oriented from the sound collector to a third arbitrary sound position in the one or more sound collection areas; a directivity direction calculation processor, which in operation, calculates a horizontal angle and a vertical angle from the sound collector to the prearranged second sound position corresponding to the directivity direction as set in accordance with a set value of the directivity direction on the setting screen displayed by the display apparatus; memory, which in operation, stores the horizontal angle and the vertical angle calculated for each of the prearranged second sound positions in the sound collection areas in association with each of the prearranged second sound positions in the sound collection areas; and an output controller, which in operation, forms directivity of the sound collected by the sound collector based on the horizontal angle and the vertical angle calculated by the directivity direction calculation processor, wherein the directivity direction calculation processor calculates the horizontal angle and the vertical angle of the directivity direction oriented to the third arbitrary sound position as designated in accordance with designation of the directivity direction oriented to the third arbitrary sound position of the one more sound collection areas on the designation screen displayed by the display apparatus, based on the horizontal angle and the vertical angle corresponding to the prearranged second sound position in the sound collection area stored in the memory.
