Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current videoconference systems face challenges in efficiently managing and displaying spherical panoramic images across communication terminals, particularly in determining and displaying specific areas of interest within these images, and in seamlessly integrating different types of image data during video communication.
Innovation Solution
The system includes communication terminals equipped with circuitry to transmit and receive image data along with layer display order information, allowing for the display of multiple images in a specific order and enabling the conversion of spherical panoramic images into predetermined-area images, which can be displayed planarly and integrated with other image types like document images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If spherical panoramic images are transmitted and displayed in full resolution, then image quality is improved, but transmission bandwidth and processing complexity increase
Solution Approach 1:
The spherical panoramic image is divided into multiple predetermined-area images representing different viewing angles. Each area image can be independently processed, transmitted, and displayed, reducing the complexity of handling the entire spherical image while maintaining high quality where needed.
Solution Approach 2:
Different areas of the spherical panoramic image can be processed and transmitted with different quality levels based on their importance. High-priority areas (such as those containing speakers or key visual elements) are transmitted in higher resolution, while less critical areas use lower resolution, optimizing bandwidth usage while preserving image quality for important regions.
2Loss of information
If multiple types of image data are integrated during video communication, then information completeness is improved, but display management complexity increases
Solution Approach 1:
The system introduces a layer dimension to manage multiple image types. Spherical panoramic images, predetermined-area images, and document images are displayed on different layers with assigned display orders. This layered approach allows comprehensive information presentation while simplifying display management through hierarchical control rather than complex spatial arrangement.
3Ease of operation
If spherical panoramic images are converted to predetermined-area images, then ease of display is improved, but image detail loss increases
Solution Approach 1:
The spherical panoramic image is segmented into multiple predetermined-area images that can be independently displayed. This segmentation allows the system to manage display complexity by showing only relevant areas rather than the entire spherical image, while preserving detailed information in each segmented area for high-quality display.
Solution Approach 2:
The system dynamically selects and displays different predetermined-area images based on viewing direction, user interaction, and importance. This dynamic approach allows the display to show detailed views of important areas while maintaining ease of operation through automated selection, reducing the need for manual navigation while preserving image details.
