3D Display Image Position and Tilt Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D display devices often fail to maximize the 3D effect due to mismatched viewing angles and distances between the user and the display screen, leading to user discomfort such as dizziness and headaches, as they are optimized for specific camera positions and viewing conditions that are rarely met in actual environments.
Innovation Solution
A method and device that adjust the output positions of 3D image data based on the user's viewing distance and tilt, using a display device equipped with sensors and user input interfaces to calculate and optimize the 3D effect by shifting and tilting the image data to match the user's viewing conditions, ensuring optimal depth perception and reduced visual fatigue.

Engineering Contradiction Analysis
1Manufacturing precision
If 3D image data is outputted with fixed camera positions and viewing angles, then the 3D effect can be maximized under specific conditions, but the user experiences dizziness and headaches when viewing conditions do not match the optimization parameters
Solution Approach 1:
The patent implements dynamic adjustment of 3D image data output positions based on real-time detection of user viewing conditions. The system continuously adapts the left and right image data positions according to the detected viewing distance and angle, transforming the fixed static output into a dynamic adaptive process that maintains optimal 3D effect across varying user positions
Solution Approach 2:
The system employs feedback mechanisms by detecting user viewing conditions (distance and angle) and using this information to adjust the 3D image data output positions. The detected viewing parameters feed back into the image processing unit, which then modifies the left and right image data positions to compensate for deviations from the optimal viewing position, creating a closed-loop control system
2Object-affected harmful factors
If the viewing distance and angle are adjusted to match user position, then visual comfort is improved, but the system complexity increases due to additional sensors and processing requirements
Solution Approach 1:
The patent introduces a viewing condition detection unit as an intermediary component that bridges the user's physical position and the image processing system. This mediator detects viewing distance and angle, converting physical spatial information into actionable data that the image processing unit can use to adjust image positions, thereby simplifying the overall control architecture
Solution Approach 2:
The system changes output parameters (left and right image data positions) based on detected viewing conditions. By adjusting these parameters dynamically, the system maintains optimal 3D effect and reduces visual fatigue without requiring fundamental changes to the display hardware architecture
