Panoramic Image Display Control With Predetermined Viewing Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods struggle to accurately display a predetermined area of a spherical panoramic image on communication terminals according to the demands of the distributor or viewer, limiting the flexibility in controlling the display direction.
Innovation Solution
The communication terminal and system include circuitry to receive and store predetermined-area information, allowing it to control the display to show the specified area of the image based on this information, enabling synchronized display directions when needed and flexible viewer control otherwise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If viewers are allowed to change display directions as desired, then ease of operation is improved, but manufacturing precision (display accuracy according to distributor demand) deteriorates
Solution Approach 1:
The system dynamically switches between two display modes: in the first mode, the display direction is fixed according to distributor demand for precise control; in the second mode, the display direction can be freely changed by viewers for enhanced flexibility. This dynamic adaptability allows the system to resolve the contradiction by providing both precision and flexibility depending on the operational context.
Solution Approach 2:
The system changes the display direction parameter based on different operational requirements. When precise control is needed, the parameter is set to match distributor demand; when flexibility is needed, the parameter allows viewer-controlled changes. This parameter adaptability enables the system to satisfy both precision and ease of operation requirements.
2Manufacturing precision
If predetermined-area information is stored and displayed, then manufacturing precision (display accuracy) is improved, but device complexity increases
Solution Approach 1:
The system extracts and stores only the necessary predetermined-area information (such as display direction and area parameters) separately from the main video stream. This extracted information can be stored in memory and applied during playback without increasing overall system complexity, as it operates as an independent control layer.
Solution Approach 2:
The system performs preliminary action by storing predetermined-area information before actual display is needed. This allows the information to be prepared in advance and retrieved during playback, reducing the computational burden during display and minimizing real-time processing complexity while maintaining high display accuracy.

AI summary
A communication terminal including circuitry to: receive video data including a captured image, from a communication management server that manages the captured image of video data distributed from another communication terminal different from the communication terminal; determine whether any predetermined-area information indicating a predetermined area of the captured image to be displayed during a reproduction time of the video data is stored in a memory; and control a display to display an image representing the predetermined area indicated by the predetermined-area information, based on a determination that the predetermined-area information is stored in the memory.
