Multi-view Stereoscopic Display Inversion Region Brightness Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-view stereoscopic displays, viewers experience discomfort due to sharp differences in viewpoint images when moving horizontally, leading to an inversion region where the left and right eye viewpoints are in adjacent areas, causing strong inversion sight stimulation and reduced comfort.
Innovation Solution
An image display method and device that periodically arranges viewing areas along a horizontal direction, with each area containing the same number of viewpoints, where the method determines if the viewer is in an inversion region and adjusts the brightness contrast of left and right eye viewpoint images by averaging their serial numbers and applying a preset brightness compensation ratio between 1% to 20% to reduce discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple viewing areas are periodically disposed along horizontal direction with multiple viewpoints in each area, then viewer freedom to watch from multiple viewpoints is improved, but brightness contrast between left and right eye images increases sharply in inversion regions causing viewer discomfort
Solution Approach 1:
The patent applies local quality by implementing different processing strategies for different spatial regions. Specifically, the system identifies inversion regions where left and right eye viewpoints are in adjacent viewing areas, and applies brightness adjustment processing only to images in these specific regions, while leaving other regions unchanged. This localized approach resolves the contradiction by maintaining multiple viewpoint freedom overall while selectively reducing harmful brightness contrast only where it occurs.
Solution Approach 2:
The patent changes the brightness parameter of viewpoint images dynamically based on the viewer's position and the identified inversion region. By adjusting the brightness parameter of left and right eye images in inversion regions, the system reduces the sharp brightness contrast that causes discomfort, while preserving the multi-view functionality in non-inversion regions.
2Adaptability or versatility
If left and right eye viewpoints are located in adjacent viewing areas in inversion region, then multi-view functionality is maintained, but stereoscopic image comfort deteriorates due to strong inversion sight stimulation
Solution Approach 1:
The patent implements preliminary action by pre-identifying inversion regions and pre-adjusting brightness parameters before the viewer actually experiences discomfort. The system determines which viewing areas constitute inversion regions in advance, and applies brightness adjustment processing to left and right eye images in these regions beforehand, preventing the strong inversion sight stimulation from occurring in the first place.
Solution Approach 2:
The patent converts the harmful inversion region effect into a beneficial outcome by using the identified inversion region information to apply targeted brightness adjustment. The system takes the previously problematic inversion region (where left and right eyes view adjacent areas causing discomfort) and transforms it into a controlled scenario where brightness adjustment processing is applied, thereby converting the harmful inversion effect into a benefit where multi-view functionality is preserved while comfort is improved.

AI summary
A multi-view stereoscopic display includes multiple viewing areas periodically disposed along a horizontal direction, and each of the multiple viewing areas includes multiple viewpoints. The method comprises obtaining a position of a viewer, determining that if the viewer is located in an inversion region, and if the position of the viewer is located in the inversion region, executing a preset process for left and right eye viewpoint images of the viewpoints respectively corresponding to the viewer's left eye and right eyes so as to decrease the brightness contrast of the left eye and the right eye viewpoint images in order to reduce the discomfort of the viewer for watching in the inversion region and adding the comfort of watching the stereoscopic image.
