1Object-affected harmful factors
If traditional holographic display methods are used, then the display can show images, but visual artifacts appear and depth perception is limited
Solution Approach 1:
The patent implements dynamic adjustment of view parameters (view cone extent, epipolar distance) based on real-time viewer position tracking. The display system continuously adapts the holographic rendering parameters to match the viewer's location, transforming a static display system into a dynamic one that eliminates visual artifacts and enhances depth perception through parameter optimization.
Solution Approach 2:
The system changes key rendering parameters including view cone extent, epipolar distance, and focal plane settings based on detected viewer position. By dynamically modifying these parameters, the system resolves the contradiction between reducing visual artifacts and maintaining reliable depth perception, as each parameter adjustment optimizes the holographic image quality for the specific viewer location.
2Ease of operation
If viewer-specific rendering is implemented, then viewing experience is improved, but computational resources and processing time increase
Solution Approach 1:
The patent applies local quality by rendering holographic views specifically tailored to each viewer's position rather than generating universal views. The system divides the viewing space into distinct regions and generates optimized rendering parameters for each region, providing high-quality viewer-specific experiences while avoiding the need to compute all possible views simultaneously.
Solution Approach 2:
The system performs preliminary tracking of viewer position and pre-computes appropriate view parameters before actual holographic rendering. By determining the viewer's location in advance and preparing the corresponding rendering parameters, the system reduces real-time computational complexity while maintaining high viewing experience quality.
3Adaptability or versatility
If multiple views are rendered for different positions, then coverage of viewing angles increases, but data processing load increases
Solution Approach 1:
The patent implements partial action by rendering only the specific views needed for detected viewer positions rather than generating all possible viewing angles. The system calculates the necessary view cone extent and epipolar distance parameters based on actual viewer location, processing only the subset of views required to achieve adequate viewing angle coverage without the excessive computational burden of rendering all potential views.
