3D Display View Curve Modification for Crosstalk Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with 3D display technologies often produce blurred images due to crosstalk between views, which affects the quality of the 3D visual effect experienced by the viewer.
Innovation Solution
A display device comprising a view generator, a view curve modifier, a 3D image data sampling module, and a display module, which generates and modifies viewing positions using an S curve to adjust pixel image data, reducing the number of views and minimizing image blurring by rearranging viewing positions and adjusting gray levels along ray vectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple views are provided to different viewing positions, then the 3D visual effect is enhanced, but image blurring and crosstalk occur between views
Solution Approach 1:
The patent extracts and removes extra view information that causes crosstalk and blurring. The view curve modifier selectively eliminates certain views from the multiple generated views, keeping only the essential views that provide 3D effect without causing image degradation. This extraction of harmful view information resolves the contradiction between providing multiple views for 3D effect and maintaining image quality.
Solution Approach 2:
The patent changes the parameter of viewing positions by modifying the view curve using an S-curve function. This transformation maps original viewing positions to modified viewing positions, effectively redistributing the views to reduce overlap and crosstalk between adjacent views. The parameter change in viewing position distribution resolves the image blurring issue while preserving the 3D visual effect.
2Manufacturing precision
If viewing positions are modified to reduce views, then crosstalk is minimized, but the number of available views decreases
Solution Approach 1:
The view curve modifier transforms the distribution of viewing positions using an S-curve function, which compresses or expands certain regions of the viewing angle spectrum. This parameter transformation allows the system to provide adequate 3D coverage with fewer actual views, as the modified viewing positions are optimally distributed to maximize 3D effect while minimizing the total number of views required.
3Adaptability or versatility
If image data is adjusted for multiple views, then 3D depth perception is improved, but processing complexity increases
Solution Approach 1:
By removing extra views through the view curve modifier, the patent reduces the number of image data sets that need to be processed and managed. This extraction of redundant view information simplifies the overall processing pipeline while maintaining the essential 3D depth perception capability, thus resolving the contradiction between 3D depth perception and processing complexity.
