Display Region Control for Omnidirectional Video Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When viewing omnidirectional moving images, users face difficulties in modifying the display region without missing important events, as existing methods require rewinding the playback position upon changing the display area, disrupting the viewing experience.
Innovation Solution
A display control apparatus and method that allows users to modify the display region during playback by detecting attitude variations and user operations, enabling seamless adjustment of the displayed area without stopping playback, and automatically updating the display region based on attitude changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display region is modified by user operation during playback, then the user can check peripheral landscape or conditions, but playback must be stopped and the user may miss events occurring outside the display region
Solution Approach 1:
The system performs preliminary action by detecting attitude variation and proactively modifying the display region before the user manually operates, thereby preventing missed events without requiring user intervention that would stop playback
Solution Approach 2:
The system uses feedback from attitude detection to automatically adjust the display region, creating a closed-loop system that responds to user viewing behavior and environmental changes without interrupting the playback flow
2Adaptability or versatility
If the display region is modified during playback, then the user can view different areas of the omnidirectional image, but the playback position must be rewound, causing loss of time
Solution Approach 1:
The system maintains continuity of useful action by keeping playback running while automatically adjusting the display region based on attitude detection, eliminating the need to stop and rewind playback
Solution Approach 2:
The system applies dynamics by making the display region adaptable and responsive to real-time attitude changes during playback, allowing seamless transitions between different viewing areas without interrupting the continuous playback flow

AI summary
A display control apparatus includes: a playback unit to play back a moving image; a display control unit to display a display region; an first acquisition unit to acquire information relating to an attitude of a display unit; a reception unit to receive an operation to modify the display region of the moving image displayed; and a control unit (1) to stop playback of the moving image and modify the display region, in a case where the reception unit receives a first predetermined operation during playback of the moving image, and (2) to modify the display region in accordance with the attitude without stopping playback of the moving image, in a case where variation in the attitude is detected on the basis of the information acquired by the first acquisition unit during playback of the moving image.
