Wide-Field Image Navigation on Multi-Viewer Display Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies struggle to facilitate the identification of where each viewer is viewing within a wide visual field image, such as a fully spherical image, making it difficult to display and navigate such images effectively.
Innovation Solution
A display terminal equipped with circuitry and memory to receive area information, display a wide visual field image, and designate and display a predetermined area image based on received information, using software like Open GL ES to create a planar representation of a fully spherical image, allowing users to identify and navigate specific areas within the image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a wide visual field image (fully spherical image) is displayed in its entirety, then the complete 360-degree visual field is shown, but the image becomes curved and difficult to view
Solution Approach 1:
The wide visual field image is divided into multiple predetermined area images, each showing a specific region of interest. Instead of displaying the entire 360-degree curved image at once, the system segments it into manageable portions that can be viewed comfortably on the display terminal.
Solution Approach 2:
The patent transforms the three-dimensional spherical image into a two-dimensional planar representation by extracting and displaying specific predetermined areas. This dimensionality change converts the curved spherical perspective into a flat, easily viewable format while preserving the essential visual information.
2Adaptability or versatility
If multiple viewers connect to view the fully spherical image simultaneously, then live streaming enables remote viewing, but it becomes difficult to identify where each viewer is viewing
Solution Approach 1:
The patent uses different colors to represent different viewers and their respective viewing areas. Each viewer's predetermined area image is displayed with a unique color code, enabling easy identification of which area each viewer is observing. This visual encoding system allows multiple users to be tracked simultaneously without confusion.
Solution Approach 2:
The system introduces an intermediary display element (the colored predetermined area images on the map) that mediates between the actual viewers and the fully spherical image. This intermediary representation allows each viewer to see where others are looking without directly observing the curved spherical image itself.
3Ease of operation
If a predetermined area image is displayed to make viewing easier, then the image becomes planar and easier to view, but navigation and identification of specific areas becomes difficult
Solution Approach 1:
The patent pre-processes the wide visual field image by identifying and marking predetermined areas of interest before display. These areas are预先 designated and stored with their spatial information, allowing the system to quickly retrieve and display relevant regions without requiring real-time navigation through the entire spherical image.
Solution Approach 2:
The system introduces an intermediary map display that shows the relationship between different predetermined areas and their locations within the fully spherical image. This intermediary representation helps users understand the spatial context and navigate between different areas without directly manipulating the curved spherical image.

AI summary
A display terminal is configured to display, on a display, a first predetermined area image of a first predetermined area as a predetermined area image of a predetermined area in a wide visual field image shared with another display terminal. The display terminal includes circuitry; and a memory storing computer-executable instructions that cause the circuitry to execute receiving area information for identifying a second predetermined area in the wide visual field image; displaying the wide visual field image and displaying, on the wide visual field image, a display area relating to the other display terminal based on the received area information; receiving a designation of the display area relating to the other display terminal; and displaying a second predetermined area image of the second predetermined area identified by the area information corresponding to the display area relating to the other display terminal, based on the received designation.
