Title
(EN) CAMERA CONTROL METHOD AND DISPLAY DEVICE
(FR) PROCÉDÉ DE COMMANDE DE CAMÉRA ET DISPOSITIF D'AFFICHAGE
(ZH) 一种摄像头的控制方法及显示设备
Abstract
(EN) Disclosed in the present application are a camera control method and a display device. The method comprises: a controller performing recognition processing on a designated image acquired by a camera to obtain a portrait area position, and calculating the azimuth distance between the area center of the portrait area position and the image center of the designated image; if the azimuth distance exceeds an azimuth set threshold, calculating, according to the azimuth distance and shooting parameters of the camera, a target adjustment angle of the camera; and on the basis of the target adjustment angle of the camera, adjusting the shooting angle of the camera, so that the portrait of a person is located in the center area of the designated image acquired by the camera.
(FR) La présente demande concerne un procédé de commande de caméra et un dispositif d'affichage. Le procédé comprend les étapes suivantes : un dispositif de commande effectue un traitement de reconnaissance sur une image désignée acquise par une caméra afin d’obtenir une position de zone de portrait, puis calcule la distance d'azimut entre le centre de zone de la position de zone de portrait et le centre d'image de l'image désignée ; si la distance d'azimut dépasse un seuil défini d'azimut, calcule, en fonction de la distance d'azimut et des paramètres de prise de vue de la caméra, un angle d’ajustement de cible de la caméra ; et d’après l'angle d’ajustement cible de la caméra, ajuste l'angle de prise de vue de la caméra afin que le portrait d'une personne se situe dans la zone centrale de l'image désignée acquise par la caméra.
(ZH) 本申请公开了一种摄像头的控制方法及显示设备,控制器对摄像头采集的指定图像进行识别处理,得到人像区域位置,计算人像区域位置的区域中心与指定图像的图像中心的方位距离;如果方位距离超过方位设定阈值,则根据方位距离和摄像头的拍摄参数,计算摄像头的目标调整角度;基于摄像头的目标调整角度,调整摄像头的拍摄角度,以使人物的人像位于摄像头采集的指定图像的中心区域。
