360-Degree Image Splitting for Seamless Multi-Screen Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for displaying 360-degree content on multiple screens fail to seamlessly manage viewpoint and view angle changes, leading to overlapping or lost regions when users control the panoramic image.
Innovation Solution
A display apparatus and server system that processes 360-degree images into split images arranged along a sphere's great circle, allowing for seamless connection and control across multiple screens through user input, including view angle and rotation adjustments, ensuring continuous and overlapping-free image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a 360-degree image is displayed on multiple screens using existing methods, then the panoramic view can be shown across multiple devices, but overlapping regions appear when viewpoint movement or zoom is applied
Solution Approach 1:
The 360-degree image is divided into multiple split images, each corresponding to a specific screen. The server segments the panoramic image data and transmits appropriate split images to each display apparatus, enabling precise control of image content on each screen without overlapping
Solution Approach 2:
The patent introduces a spherical coordinate system with longitude and latitude to map the 360-degree image onto multiple screens arranged in three-dimensional space. This dimensional transformation allows the system to calculate precise projection positions for each screen based on its spatial location, eliminating overlapping regions
2Ease of operation
If viewpoint movement is controlled on each screen independently, then user interaction flexibility increases, but seamless connection between screen regions is lost
Solution Approach 1:
The system establishes a main screen that receives user input and transmits control information to other screens. When a user interacts with the main screen, the server calculates the corresponding viewpoint changes for all other screens and transmits updated control information, ensuring all screens move their images in coordination to maintain seamless connections
Solution Approach 2:
The patent merges the control of multiple screens under a unified system where all screens share a common reference point and coordinate system. The main screen acts as the central control node, and all other screens are synchronized to it, creating a unified multi-screen experience rather than independent displays
3Adaptability or versatility
If the view angle is changed to accommodate different screen configurations, then adaptability to various display arrangements improves, but overlapping or lost regions may occur
Solution Approach 1:
The system dynamically adjusts the view angle and image projection parameters based on the specific configuration of screens. The server receives information about screen positions and arrangements, then calculates optimal projection parameters for each screen to prevent overlapping while ensuring complete coverage of the 360-degree image without lost regions

AI summary
A display apparatus is provided. The display apparatus includes: an image processor configured to process an image signal; a display; and a processor configured to control the image processor to produce, from a 360-degree image, a plurality of split images to be arranged along a circumference within a predetermined region that includes a great circle of a sphere shape being mapped, based on a viewpoint corresponding to a user input, the plurality of split images corresponding to a plurality of screens, and to produce a projection image to be displayed on the display based on the viewpoint from the split image of the screen that corresponds to the display apparatus from among the plurality of split images.
