(JA) 収音装置、収音方法、及びプログラム
Abstract:
(EN) This sound pickup device is for picking up a target sound output from an object which is the sound source. The sound pickup device includes a control unit that: generates object location information indicating the location of the object, on the basis of image data from a camera; generates sound-source location information indicating the location of the sound source, on the basis of acoustic signals from a microphone array; sets, for the object location information, a weighting which depends on the image capturing state of the camera; and determines the direction for picking up the target sound, on the basis of the object location information, the object location information weighting, and the sound-source location information.
(FR) L'invention concerne un dispositif de prise de son destiné à capter une sortie sonore cible à partir d'un objet qui est la source sonore. Le dispositif de prise de son comprend une unité de commande qui : génère des informations de localisation d'objet indiquant la localisation de l'objet, en fonction de données d'image provenant d'une caméra ; génère des informations de localisation de source sonore indiquant la localisation de la source sonore, en fonction de signaux acoustiques provenant d'un réseau de microphones ; définit, pour les informations de localisation d'objet, une pondération qui dépend de l'état de capture d'image de la caméra ; et détermine la direction de prise du son cible, en fonction des informations de localisation d'objet, de la pondération d'informations de localisation d'objet et des informations de localisation de source sonore.
(JA) 収音装置は、音源となる物体から出力される目的音を収音するための装置であって、カメラの画像データに基づいて、物体の位置を示す物体位置情報を生成し、マイクアレイの音響信号に基づいて、音源の位置を示す音源位置情報を生成し、物体位置情報に対してカメラの撮影状況に応じた重みを設定し、物体位置情報と物体位置情報の重みと音源位置情報とに基づいて、目的音を収音する方向を決定する制御部を含む。
