Abstract
(EN)
Provided in the present invention are a method and device for video local zooming. The method comprises: acquiring pressure sensing data detected in a video playback area on a terminal screen; acquiring a first local video in the video playback area and a zoom factor for the first local video on the basis of the pressure sensing data; and zooming the first local video on the basis of the zoom factor. The present invention solves the problem in the prior art that a video conference picture cannot be locally zoomed for display during a video conference.
(FR)
La présente invention concerne un procédé et un dispositif de zoom vidéo local. Le procédé consiste à : acquérir des données de détection de pression détectées dans une zone de lecture vidéo sur un écran terminal; l'acquisition d'une première vidéo locale dans la zone de lecture vidéo et d'un facteur de zoom pour la première vidéo locale sur la base des données de détection de pression; et à effectuer un zoom sur la première vidéo locale sur la base du facteur de zoom. La présente invention résout le problème de l'art antérieur selon lequel une image de vidéoconférence ne peut pas être zoomée localement pour être affichée pendant une vidéoconférence.
