3D Display Parallax Compensation for Stereoscopic Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional three-dimensional display systems lose the stereoscopic effect when new objects are introduced, relative movement occurs between the virtual camera and objects, or focus shifts within the scene, leading to an uncomfortable viewing experience due to inappropriate parallax settings.
Innovation Solution
A method that determines the distance between a virtual camera and a center of interest, calculates a scaling factor based on this distance, and applies it to compensate for parallax settings when generating the three-dimensional image to maintain the stereoscopic effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed parallax setting is used for a predetermined scale of objects, then the three dimensional stereoscopic effect is maintained for that specific scale, but the stereoscopic effect is lost when new objects are introduced, relative movement occurs, or focus shifts
Solution Approach 1:
The patent applies dynamics by making the parallax setting adjustable and adaptive rather than fixed. The system dynamically modifies parallax parameters based on detected changes in object scale, camera position, or focus points, allowing the stereoscopic effect to be maintained across varying conditions. This resolves the contradiction by enabling the system to adapt to different object scales and scene configurations while preserving the three-dimensional effect.
Solution Approach 2:
The patent implements parameter changes by modifying parallax settings in response to detected changes in scene parameters such as object scale, camera position, or focus. When the system detects that objects have been introduced or removed, or when the camera moves, it adjusts the parallax parameters accordingly to maintain the stereoscopic effect. This allows the system to adapt to varying conditions while preserving the three-dimensional viewing experience.
2Adaptability or versatility
If parallax settings are adjusted to accommodate new objects or movement, then adaptability is improved, but the three dimensional stereoscopic effect may be lost due to inappropriate parallax settings
Solution Approach 1:
The patent implements feedback by continuously monitoring scene parameters such as object positions, camera movement, and focus points, and using this information to adjust parallax settings. The system detects changes in the scene and modifies parallax parameters in response, creating a closed-loop control system that maintains the stereoscopic effect while adapting to new conditions. This feedback mechanism ensures that parallax adjustments are made appropriately to preserve the three-dimensional effect.
3Device complexity
If a conventional fixed parallax system is used, then device complexity is low, but the system becomes unviewable and causes physical discomfort when stereoscopic effect is lost
Solution Approach 1:
The patent applies dynamics by implementing a dynamic parallax adjustment system that responds to scene changes. Rather than using a fixed, simple parallax setting, the system continuously adapts parallax parameters based on detected changes in objects, camera position, or focus. This dynamic approach prevents the loss of stereoscopic effect that would otherwise cause viewer discomfort, while adding only the necessary complexity to maintain viewing comfort.

AI summary
Maintaining a three dimensional stereoscopic effect may include determining a distance between a position of a virtual camera and a first center of interest of a three dimensional image, calculating a scaling factor based on the distance, and compensating for a parallax setting associated with a second center of interest within the three dimensional image by applying the scaling factor when generating the three dimensional image to maintain the three dimensional effect.
