360-Degree Panoramic Background for Video Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video call technologies fail to effectively protect user privacy by transmitting personal location and environment information, and provide monotonous background options that do not fully obscure the user's surroundings.
Innovation Solution
A method and apparatus that replace the original background video with a 360-degree panoramic video image during a video call, allowing the panoramic video image to move in response to user motion and be shared with a counterpart terminal, while maintaining the replacement background video based on set time information, thereby enhancing privacy and providing a more engaging experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional background stickers are used to replace the background video, then privacy protection is improved, but the background becomes monotonous and lacks realism
Solution Approach 1:
The patent applies the dynamics principle by replacing static background stickers with dynamic 360-degree panoramic videos that can move and change based on user motion information. The background is no longer fixed but dynamically adjusts to user actions, providing both privacy protection and visual engagement.
Solution Approach 2:
The patent transitions from two-dimensional flat background stickers to three-dimensional immersive 360-degree panoramic videos. This dimensional change allows users to experience a more realistic and engaging virtual background while maintaining privacy protection.
2Adaptability or versatility
If the original background video is transmitted during video call, then realism and shared space are improved, but user privacy is compromised due to exposure of location and surrounding environment
Solution Approach 1:
The patent extracts the harmful element (original background containing personal location and environment information) from the video call transmission. By separating and replacing the background with a 360-degree panoramic video, the system removes the privacy risk while preserving the visual experience.
Solution Approach 2:
The patent creates a copy of the background environment using pre-captured 360-degree panoramic videos. Instead of transmitting the actual background that reveals personal information, the system uses a replicated virtual background that provides the same visual function without the privacy risk.
3Reliability
If 360-degree panoramic video is used as replacement background, then privacy protection and immersive experience are improved, but device complexity and processing requirements increase
Solution Approach 1:
The patent applies preliminary action by pre-capturing and storing 360-degree panoramic videos before the video call. This preparation work is done in advance, reducing the processing burden during the actual call. The system only needs to retrieve and display the pre-prepared panoramic video rather than generating it in real-time.
Data Source
AI summary
Disclosed is a method and apparatus for providing a 360-degree panoramic background during a video call. A non-transitory computer-readable recording medium stores instructions that, when executed by a processor, cause the processor to perform operations for providing a background on an electronic device. The operations include separating an object video and an original background video from video data input to a first video call screen of an electronic device during a video call; generating new video data by synthesizing a panoramic video image and the object video such that the new video data includes the object video and includes the panoramic video image as a replacement background video; and displaying, on the first video call screen, the new video data such that a location of the panoramic video image of the new video data moves in response to motion information of a user.
