Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stereoscopic image technologies struggle to provide optimal three-dimensional effects for both personalized and general-purpose displays, especially when users want to adjust the focus on a specific object in motion.
Innovation Solution
A stereoscopic video generating device that uses plenoptic video data to identify and track a user-designated object, applying rendering techniques based on depth values to create either binary or multiple viewpoint videos depending on the display type, enhancing three-dimensional effects for both personalized and general-purpose displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If initial fixed viewpoint values are used for stereoscopic displays, then device complexity is reduced, but the three-dimensional effect deteriorates when objects move back and forth
Solution Approach 1:
The patent implements dynamic viewpoint adjustment by tracking object movement and automatically modifying the stereoscopic viewpoint parameters in real-time. This allows the system to maintain optimal three-dimensional effects for moving objects without requiring complex manual reconfiguration, resolving the contradiction between system simplicity and rendering reliability.
2Manufacturing precision
If preset fixed focus values are used for general-purpose displays, then manufacturing precision requirements are reduced, but the adaptability deteriorates when users want to adjust focus on specific objects
Solution Approach 1:
The system automatically performs focus adjustment by identifying user-selected objects and dynamically modifying focus parameters based on object depth and position. This self-adjusting mechanism eliminates the need for manual focus calibration while providing adaptive focus control for different objects in the scene, resolving the contradiction between manufacturing precision and user adaptability.
3Speed
If binary viewpoint rendering is used for personalized displays, then processing speed is improved, but the three-dimensional effect deteriorates for objects at varying depths
Solution Approach 1:
The patent applies selective rendering techniques where full multi-viewpoint processing is applied only to identified objects of interest, while other areas use simplified rendering. This partial application of complex processing maintains high rendering speed while improving three-dimensional effects for specific objects, resolving the contradiction between speed and rendering quality.
