PROBLEM TO BE SOLVED: To provide a directivity control system capable of forming sound pickup directivity of voices toward a position corresponding to a position which is specified based on an image of a predetermined range where a camera apparatus picks up an image with respect to a microphone array device as a reference to thereby accurately pick up a piece of voice data, and a directivity control method.SOLUTION: In a directivity control system 10, a signal processing part 33 derives a sound pick-up direction (θ,θ) toward a voice position, which corresponds to a position of a piece of image data specified in a screen, from an installation position of a microphone array unit 2 according to a specification of any position made by a user via a piece of image data displayed on a screen of a display unit 36. The signal processing part 33 forms a sound pickup directivity of the voice data in the derived sound pick-up direction (θ,θ).SELECTED DRAWING: Figure 1 【課題】マイクアレイ装置を基準として、カメラ装置が撮像する所定範囲の映像から指定された位置に対応する場所に向けて音声の収音指向性を形成し、音声データを高精度に収音する指向性制御システム及び指向性制御方法を提供する。【解決手段】指向性制御システム１０では、信号処理部３３は、ディスプレイ装置３６の画面に表示された映像データの中からユーザの任意の位置の指定に応じて、マイクアレイ装置２の設置位置から画面内にて指定された映像データの位置に対応する音声位置に向かう収音方向（θＭＡｈ，θＭＡｖ）を導出する。信号処理部３３は、導出された収音方向（θＭＡｈ，θＭＡｖ）に音声データの収音指向性を形成する。【選択図】図１
