Title
(EN) SCREEN CAPTURE METHOD AND ELECTRONIC DEVICE
(FR) PROCÉDÉ DE CAPTURE D'ÉCRAN ET DISPOSITIF ÉLECTRONIQUE
(ZH) 一种截屏方法及电子设备
Abstract
(EN) A screen capture method and an electronic device. The method comprises: in response to a screen capture operation of a user, an electronic device performing screen capture on a video multiple times within a period of time; intelligently detecting a target to be processed in the multiple instances of screen capture and processing same as a transparent region; and superimposing processed screenshot images, so as to obtain a final screenshot image. During screen capture on a video, a background can be prevented from being shielded by a person, such that a screenshot image displays more information.
(FR) Procédé de capture d'écran et dispositif électronique. Le procédé comprend les étapes suivantes : la réalisation, par un dispositif électronique, en réponse à une opération de capture d'écran d'un utilisateur, d'une capture d'écran sur une vidéo plusieurs fois dans une période de temps ; la détection de manière intelligente d'une cible à traiter dans les multiples instances de capture d'écran et le traitement de celles-ci en tant que région transparente ; et la superposition des images de capture d'écran traitées, de façon à obtenir une image de capture d'écran finale. Pendant la capture d'écran sur une vidéo, un arrière-plan peut être empêché d'être protégé par une personne, de telle sorte qu'une image de capture d'écran affiche plus d'informations.
(ZH) 一种截屏方法和电子设备。在该方法中,响应于用户的截屏操作,电子设备在一个时间段内对视频进行多次截屏,智能检测出该多次截屏中的待处理目标并处理为透明区域,将处理后的截屏图片进行叠加,得到最终截屏图片。在对视频截屏时可以避免人物对背景的遮挡,使得截屏图片显示更多的信息。
