Wide-View Image Display Control with Viewpoint and Scroll Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in distinguishing between operations for changing the virtual viewpoint and scrolling in wide-view images, leading to conflicts when using a single operation like dragging, especially in displaying wide-view images such as spherical images.
Innovation Solution
A system and method that differentiate between first and second operations on a predetermined-area image within a wide-view image, where the first operation changes the virtual viewpoint and the second operation scrolls the image, ensuring distinct actions for each.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single operation (dragging) is used to both change virtual viewpoint and scroll the image, then the ease of operation is improved, but the reliability of operation distinction deteriorates causing conflict
Solution Approach 1:
The patent segments the operation types into distinct categories: first operations (e.g., clicking, tapping) are assigned to change virtual viewpoint, while second operations (e.g., dragging, swiping) are assigned to scroll the image. This segmentation resolves the conflict by ensuring each operation type has a dedicated function, eliminating ambiguity and improving reliability while maintaining ease of use through clear operational guidelines.
2Manufacturing precision
If a predetermined-area image is displayed from a wide-view image, then the manufacturing precision of display content is improved, but the device complexity increases
Solution Approach 1:
The patent implements a dynamic display system where the predetermined-area image can be interactively adjusted based on user operations. The system dynamically switches between displaying the predetermined-area image and the full wide-view image, and allows real-time modification of the predetermined area through user interactions. This dynamic approach maintains display precision while managing complexity through flexible, user-driven control rather than rigid fixed configurations.

AI summary
A system of controlling display includes a display, and circuitry that controls the display to display a screen including a predetermined-area image representing a viewable area of a wide-view image. In response to detection of a first operation on the predetermined-area image, the circuitry performs first processing of displaying another predetermined-area image representing another viewable area of the wide-view image, said another viewable area reflecting a change in virtual viewpoint to the wide-view image. In response to detection of a second operation on the predetermined-area image, the second operation being different than the first operation, the circuitry performs second processing of scrolling the predetermined-area image in the screen.
