Multi-Viewpoint Image Display with Resolution Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-viewpoint video distribution systems face challenges in efficiently transmitting and displaying videos from various viewpoints to multiple users, requiring significant bandwidth and complicating system configuration, especially when users need to switch viewpoints in real-time.
Innovation Solution
The system generates and transmits an integrated image with low-resolution images from different viewpoints, allowing users to select and switch to high-resolution images from the same viewpoint, reducing data transmission and enabling seamless viewpoint changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple high-resolution video streams are transmitted for multi-viewpoint switching, then viewpoint switching capability is improved, but bandwidth consumption increases significantly
Solution Approach 1:
The video content is segmented into two resolution levels: low-resolution streams for all viewpoints and high-resolution streams for selected viewpoints. This segmentation allows the system to provide multi-viewpoint capability while controlling bandwidth by only transmitting high-resolution data for viewpoints that are currently selected or frequently accessed.
Solution Approach 2:
Different quality levels are applied to different viewpoints based on their importance and selection frequency. High-resolution video is transmitted only for selected viewpoints, while low-resolution video is transmitted for all viewpoints. This local quality differentiation optimizes bandwidth usage while maintaining viewing quality for important angles.
2Measurement precision
If high-resolution images are displayed immediately upon selection, then image quality is improved, but display continuity is degraded due to switching time
Solution Approach 1:
Low-resolution preview images of all viewpoints are displayed in advance within the integrated image. When a user selects a viewpoint, the corresponding high-resolution image is already prepared and can be switched to immediately, eliminating display continuity loss while maintaining the ability to provide high-quality images upon selection.
Solution Approach 2:
The low-resolution images are nested within the integrated image structure, with each low-resolution image serving as a thumbnail or preview. When a user selects a low-resolution image, the corresponding high-resolution image is activated. This nested structure allows seamless transitions between preview and full-quality display without interruption.
3Loss of time
If low-resolution images are displayed in larger size during transition, then display continuity is improved, but temporary image quality deteriorates
Solution Approach 1:
The display transitions follow a periodic pattern: low-resolution images are displayed at normal size during browsing, then enlarged during transition, and finally replaced by high-resolution images. This periodic size adjustment maintains display continuity while temporarily accepting reduced quality only during the brief transition phase, after which full quality is restored.

AI summary
An image display method includes receiving an integrated image in which low-resolution images of a scene from different viewpoints are arranged, displaying the integrated image such that a low-resolution image among the low-resolution images is displayed in a first size, receiving a high-resolution image having a same viewpoint as the low-resolution image, the high-resolution image having a higher resolution than the low-resolution image, displaying the high-resolution image in a second size larger than the first size, and displaying the low-resolution image in a third size larger than the first size after the integrated image is displayed and before the high-resolution image is displayed in the second size.
