Wide-Field Image Display With Planar Viewpoint Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies struggle to facilitate the identification of where each viewer is viewing in a wide visual field image, such as a fully spherical image, making it difficult to navigate and view specific areas within the image.
Innovation Solution
A display terminal and communication system that processes fully spherical images using software like Open GL ES to convert them into planar images, allowing for the display of predetermined areas with minimal curvature, and incorporates virtual cameras to adjust the viewpoint and angle of view, enabling precise identification of viewing directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the entirety of a wide visual field image is displayed by a display terminal, then the complete 360-degree image is shown, but the image becomes curved and difficult to view
Solution Approach 1:
The wide visual field image is divided into a predetermined area (first predetermined area) and other areas. The display terminal displays only the predetermined area as a planar image, separating it from the rest of the spherical image. This segmentation allows the displayed portion to be flat and easy to view while the complete spherical image remains intact in the background.
2Loss of information
If points of interest and display direction marks are added to indicate viewer positions, then viewer location information is provided, but the display becomes more complex
Solution Approach 1:
A map image serving as an intermediary is generated and displayed alongside the predetermined area image. This map image visually represents the positions of multiple viewers and their respective predetermined areas without requiring complex markers or indicators on the main image. The intermediary map provides clear spatial information in a simplified manner.

AI summary
A display terminal is configured to display a predetermined area image of a predetermined area in a wide visual field image. The display terminal includes circuitry; and a memory storing computer-executable instructions that cause the circuitry to execute displaying, on a display, a first predetermined area image of a first predetermined area in the wide visual field image, and the wide visual field image. The displaying includes displaying a display area corresponding to the first predetermined area on the wide visual field image displayed on the display.
