Description

Stereoscopic display method of video conference and video conference system Technical Field The present invention relates to a display method and a conference system, and more particularly, to a stereoscopic display method and a video conference system for a video conference. Background In recent years, stereoscopic images have been increasingly used, and naked-eye stereoscopic displays have been developed from early stereoscopic glasses to date. Particularly when video conferences are in progress, it may be desirable to present a stereoscopic object. At this time, if the object can be presented in a three-dimensional mode, the opposite party can have visual feeling of body calendar, so that the actual situation can be closed in the conference process, and the conference is smoother. Disclosure of Invention The invention relates to a stereoscopic display method of a video conference and a video conference system, which encode images into hidden watermarks, so that stereoscopic imaging can be obtained according to the decoded hidden watermarks when the images are transmitted to other electronic devices.
