Title
(EN) DISPLAY METHOD AND DISPLAY DEVICE
(FR) PROCÉDÉ D'AFFICHAGE ET DISPOSITIF D'AFFICHAGE
(ZH) 一种显示方法及显示设备
Abstract
(EN) Disclosed are a display method and a display device, wherein a camera can rotate within a pre-set angle range, and a controller is configured to: acquire character sound source information collected by a sound collector and perform sound source identification, so as to determine sound source angle information which is used for identifying an azimuth angle of the position of a person; on the basis of the current photographing angle and the sound source angle information of the camera, determine a target rotation direction and a target rotation angle of the camera; and adjust the photographing angle of the camera according to the target rotation direction and the target rotation angle, such that a photographing area of the camera directly faces the position of the person when he/she is speaking.
(FR) Sont divulgués un procédé d'affichage et un dispositif d'affichage. Une caméra peut tourner dans une plage angulaire prédéfinie et un dispositif de commande est configuré pour : acquérir des informations de source sonore de personnage collectées par un collecteur sonore et effectuer une identification de source sonore, de façon à déterminer des informations d'angle de source sonore utilisées pour identifier un angle d'azimut de la position d'une personne ; en fonction de l'angle de prise de vue en cours et des informations d'angle de source sonore de la caméra, déterminer une direction de rotation cible et un angle de rotation cible de la caméra ; et régler l'angle de prise de vue de la caméra en fonction de la direction de rotation cible et de l'angle de rotation cible, de telle sorte qu'une zone de prise de vue de la caméra fasse directement face à la position de la personne lorsqu'elle parle.
(ZH) 本申请公开了一种显示方法及显示设备,其中的摄像头可在预设角度范围内转动,控制器被配置为获取声音采集器采集的人物声源信息并进行声源识别,确定用于标识人物所在位置的方位角度的声源角度信息;基于摄像头的当前拍摄角度和声源角度信息,确定摄像头的目标转动方向和目标转动角度;按照目标转动方向和目标转动角度,调整摄像头的拍摄角度,以使摄像头的拍摄区域正对人物语音时的所处位置。
