Dynamic Display Range Control for Wide-Range Video Posture Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for displaying wide-range video images limit user visibility by consistently showing only the viewing direction with the most users, preventing the user from seeing other portions, even when they are interested in them, and failing to highlight important information when it is not displayed.
Innovation Solution
An electronic apparatus with a detection unit to sense the posture of a display unit, a reproduction unit to adjust the display range based on the detected posture, and a control unit to ensure the main object is displayed regardless of posture, allowing the display range to change when switching between frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display range is automatically switched to the viewing direction in which more users are looking, then the highlight of the moving image is displayed, but the user cannot see other portions of the wide-range image
Solution Approach 1:
The patent applies dynamics by making the display range adjustable and changeable based on user interaction. The system transitions from a static automatic switching mode to a dynamic mode where the display range can be modified according to user needs, allowing both highlight visibility and user-controlled exploration of different portions.
Solution Approach 2:
The patent uses partial action by displaying only a portion of the wide-range image at a time, specifically focusing on the highlight area when automatically switched. This selective display emphasizes important content while allowing users to request additional portions when needed.
2Loss of information
If the display range is fixed to show the viewing direction with the most users, then the highlight is always visible, but the user may not notice the highlight when viewing other portions
Solution Approach 1:
The patent implements feedback by detecting user operations and responding by changing the display range accordingly. When a user interacts with the interface to view a different portion, the system receives this feedback and adjusts the display range to accommodate the user's request while maintaining highlight visibility when appropriate.
Solution Approach 2:
The system provides self-service functionality by allowing users to control the display range according to their own needs. Users can independently adjust what they want to see without being forced into a predetermined automatic switching mode, empowering them to manage their own viewing experience.
3Adaptability or versatility
If the display range changes according to user operations, then the user can view different portions, but the highlight may not be displayed consistently
Solution Approach 1:
The patent applies local quality by treating the highlight area differently from other portions of the image. The highlight receives special handling in the display logic, ensuring it maintains visibility consistency through techniques such as prioritized positioning or visual emphasis, while other portions are displayed based on user requests.

AI summary
An electronic apparatus includes: a detection unit configured to detect a posture of a display unit; a reproduction unit configured to reproduce a moving image; a change unit configured to change a display range according to the posture of the display unit; and a control unit configured to perform control so that in a case where a first frame of the moving image is reproduced, a main object is displayed on the display unit regardless of whether the posture is a first posture or a second posture, and perform control so that in a case where a second frame, which is different from the first frame, of the moving image is reproduced, the display range differs between a case where the detected posture is the first posture and a case where the detected posture is the second posture.
