3D Video Depth Perception Adjustment for User Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D video call technologies face challenges in providing optimal depth perception due to large data burdens on transmission networks and inconsistent quality, as 3D videos are not adjusted based on the user's position or display settings, leading to suboptimal viewing experiences.
Innovation Solution
A method and device that utilize a depth sensor to detect a user's position and adjust the depth perception of 3D videos by calculating the range of maximum and minimum depths, scaling the depth video according to user input, and optimizing the left and right stereo video generating interval to ensure an optimal 3D effect, while reducing data transmission requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 3D video is provided by obtaining left and right videos, then three-dimensional effect is represented, but data amount increases significantly imposing burden on transmission network
Solution Approach 1:
The patent extracts only the essential depth information from the 3D video data, separating it from the full left-right video pair. By transmitting depth maps or depth-related parameters instead of complete stereo video pairs, the system maintains the three-dimensional effect while significantly reducing the data amount that needs to be transmitted over the network.
Solution Approach 2:
The patent uses depth maps as a simplified representation or copy of the full 3D scene information. Instead of transmitting actual left and right video sequences, the system transmits depth information that can be used to reconstruct or simulate the three-dimensional effect at the receiving end, thereby reducing data transmission requirements while preserving the essential 3D viewing experience.
2Reliability
If 3D video is provided by obtaining left and right videos, then three-dimensional effect is represented, but quality is inconsistent as it does not adjust to user position or display settings
Solution Approach 1:
The patent implements dynamic adjustment of 3D video parameters based on detected user position and display characteristics. The system continuously adapts the depth perception and stereo video generating interval according to the user's viewing distance and angle, ensuring consistent quality across different viewing conditions and user positions rather than providing a fixed 3D effect.
Solution Approach 2:
The patent incorporates feedback mechanisms where the system detects user position information and display settings, then uses this information to adjust the 3D video rendering parameters. This closed-loop approach ensures that the three-dimensional effect adapts to actual viewing conditions, maintaining quality consistency regardless of user position or display variations.
3Ease of operation
If depth perception is adjusted based on user position, then optimal 3D video experience is achieved, but device complexity increases with depth sensor and processing requirements
Solution Approach 1:
The patent introduces a depth sensor as an intermediary device that bridges the gap between the user and the 3D video system. This sensor captures depth information that serves as input for adjusting the stereo video generating interval, enabling automatic adaptation without requiring complex user input or manual configuration, thus improving ease of operation while managing device complexity through a dedicated sensing component.

AI summary
A method and a device for adjusting depth perception, a terminal including a function for adjusting depth perception and a method for operating the terminal are provided. The method for adjusting depth perception includes: obtaining color and depth videos of a user; detecting a user's position based on the obtained depth video of the user; calculating a range of maximum and minimum depths in a 3-dimensional (3D) video according to the detected user's position; and adjusting a left and right stereo video generating interval of the 3D video to be rendered so as to satisfy the calculated range of the maximum and minimum depths. Therefore, during a 3D or multi-view video call, the 3D video having a three-dimensional effect optimized according to the user's position may be provided.
