Example Embodiment

[0038] The invention discloses a video synthesis method. The difference from traditional video synthesis is that the video is received while synthesizing the video with the existing video. Specifically, the synthesis process takes image frames as the unit , As long as the collected image frame is received, it will be combined with the image frame in the video currently displayed by the display unit, achieving the purpose of combining while shooting. Corresponding to the method, the present invention also discloses a video synthesis device and electronic equipment, which are used to synthesize videos in real time.

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of...

Abstract

The invention provides a video synthesis method which is used for electronic equipment provided with a display unit and at least two image acquisition units. The video synthesis method includes that images acquired by the at least two image acquisition units are received, and an image frame of a first video is produced by the utilization of the images; at least a part of displayed images of the display unit is obtained, an image frame of a second video is produced, the image frame of the first video and the image frame of the second video are synthesized to be as an image frame of a third video; and the steps are repeated sequentially until the image acquisition units stop image acquisition. The invention further provides a corresponding device and electronic equipment of the method, the corresponding device and the electronic equipment of the method comprise a generating unit of the image frame of the first video, a generating unit of the image frame of the second video and a video synthesis unit. The video synthesis method, the device and the electronic equipment achieve the purpose that videos are synthesized with existing videos while the videos are collected, and therefore video synthesis real-time requirements are met.

Description

technical field [0001] The invention relates to the field of multimedia communication, in particular to a video synthesis method, device and electronic equipment. Background technique [0002] Video synthesis is a common technology in video production. For example, for a certain requirement, take a video of a speaker, and then use the existing video as the background to synthesize the two into an image. Because it needs to be considered in the synthesis process The matching between the captured video and the existing video, for example, if the captured video is 3D and the existing 2D video, the matching between 3D and 2D should be taken into account when compositing, so the current common practice is to complete the shooting first and then the video Synthesis, post-production and other processes, this method can only perform video synthesis after the shooting is completed, but cannot achieve synthesizing while shooting, so it cannot meet the real-time requirements.
