Autostereoscopic Display Dynamic View Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autostereoscopic displays face limitations in viewer mobility due to fixed viewing positions, resolution loss, and issues with cone transitions and crosstalk, particularly when multiple viewers or varying distances are involved.
Innovation Solution
An autostereoscopic display system with a viewer tracking system that dynamically adjusts the number and arrangement of views based on viewer position and movement, allowing for flexible switching between two-view and multi-view modes, and optimizing image sharpness by reducing view overlap and cone transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a barrier or lenticular arrangement is used to provide stereoscopic views, then 3D perception is enabled, but horizontal resolution is reduced by a factor of n
Solution Approach 1:
The patent implements a dynamic view allocation system that adjusts the number of views displayed in different viewing areas based on viewer position and content requirements. The processor dynamically controls which views are allocated to which viewing areas, allowing the system to optimize between 3D effect strength and resolution preservation by adjusting view repetition patterns in different spatial zones.
Solution Approach 2:
The patent applies different view allocation strategies to different viewing areas. The processor can assign different numbers of views to different viewing areas based on local requirements - for example, allocating more views to areas where viewers are positioned to maintain resolution, while allocating fewer views to areas where 3D effect is prioritized.
2Adaptability or versatility
If the number of views is increased to accommodate multiple viewers or larger viewing distances, then viewing flexibility is improved, but image sharpness deteriorates due to view overlap
Solution Approach 1:
The patent implements a dynamic view allocation system that adjusts the number of views displayed in different viewing areas based on viewer position and content requirements. The processor dynamically controls which views are allocated to which viewing areas, allowing the system to optimize between 3D effect strength and resolution preservation by adjusting view repetition patterns in different spatial zones.
Solution Approach 2:
The patent changes the parameter of view allocation dynamically based on viewing distance and position. The processor adjusts the number of views allocated to each viewing area according to the detected viewer position, changing system parameters in real-time to maintain optimal image sharpness while accommodating viewing flexibility requirements.
3Reliability
If head tracking is used to avoid cone transitions, then viewing experience is improved, but device complexity increases
Solution Approach 1:
The patent pre-calculates and prepares multiple view configurations that can be quickly switched based on viewer position. Instead of continuous real-time adjustment, the system pre-prepares different view allocation patterns and switches between them based on detected viewer position, reducing the complexity of real-time processing while maintaining smooth viewing experience.

AI summary
The invention provides an autostereoscopic display device in which a viewer tracking system determines a position of a viewer with respect to the display panel. The display panel is controlled to display a number of different views which is dependent on at least the distance of the viewer from the display panel. This enables the number of views to optimised with respect to the position and/or speed of movement of the viewer.
