Glassless 3D Display Image Processing for Viewing Position Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current glassless 3D display systems are costly and limited in accommodating multiple viewers at different positions and viewing distances, as they require adjustable light splitters and external position sensors to ensure optimal viewing experiences.
Innovation Solution
An image processing system that modifies original images by adding identifiers to specific views, allowing viewers to determine their optimal viewing position based on the combination of these identifiers, eliminating the need for adjustable light splitters and external sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an adjustable light splitter is used to ensure continuous viewing region, then viewing quality is improved, but production cost increases remarkably
Solution Approach 1:
The patent uses image data copying and processing to create multiple views with identifiers instead of using physical adjustable light splitters. The system processes original image data to generate target image data with embedded identifiers that guide viewers to correct viewing positions, eliminating the need for expensive adjustable optical components.
Solution Approach 2:
The patent replaces the mechanical/optical adjustable light splitter system with an image processing system. Instead of physically adjusting light paths using controllable light splitters, the system uses digital image processing to embed viewing position information directly in the displayed image, substituting mechanical adjustment with information-based guidance.
2Adaptability or versatility
If an adjustable light splitter is used to adapt to different viewing distances, then viewing adaptability is improved, but device complexity increases
Solution Approach 1:
The system creates multiple copied views with different identifiers embedded in the image data. Each view contains information about its optimal viewing position, allowing the system to adapt to different viewing distances and positions without requiring complex adjustable optical components.
Solution Approach 2:
The patent implements self-service by embedding viewing position information directly in the displayed image. Viewers can independently determine their optimal viewing position by observing the identifiers in the image, without requiring external sensors or active system adjustment, thereby reducing device complexity.
3Measurement precision
If external position sensors are used to determine viewer position, then position detection precision is improved, but production cost increases
Solution Approach 1:
Instead of using external position sensors, the system embeds position information directly in the image data. The identifiers copied into each view serve as internal position markers that viewers can use to determine their location without requiring external detection devices.
Solution Approach 2:
The system performs self-detection by embedding viewing position information within the displayed image itself. Viewers can determine their position by observing the identifiers in the image, eliminating the need for external position sensors and reducing production costs.
4Measurement precision
If image data is processed to add identifiers to multiple views, then viewer guidance accuracy is improved, but image processing complexity increases
Solution Approach 1:
The patent segments the original image into multiple views, each assigned a unique identifier. This segmentation allows precise guidance of different viewers to different viewing positions while maintaining manageable processing complexity through systematic division of the image data.
Solution Approach 2:
The system applies different identifiers to different local regions (views) of the image data. Each view contains localized position information tailored to its specific viewing angle and distance, providing accurate guidance for viewers at different positions without requiring complex global processing.
