Multi-Camera Rotatable Display Control for Centered User Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rotatable display apparatuses face challenges in accurately photographing users as the camera's photographing direction changes with the display's orientation, leading to inconvenience for users who need to adjust their position to be captured correctly.
Innovation Solution
A display apparatus with multiple cameras, including at least one with a wider angle of view, that automatically adjusts its photographing direction based on the display's orientation, using a processor to control camera rotation and ensure the user remains centered in the frame regardless of the display's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera is disposed on top of the rotatable display apparatus, then the photographing direction of the camera changes with the display orientation, but this causes the user to be photographed incorrectly when the camera faces upward
Solution Approach 1:
The camera system is divided into multiple independent cameras (first camera and second camera) that can be selectively activated based on display orientation. This segmentation allows the system to maintain reliable photographing by switching between cameras rather than relying on a single camera that must adapt to all orientations.
Solution Approach 2:
The system dynamically switches between different cameras based on the real-time orientation of the display. When the display is in a first orientation, the first camera is used; when rotated to a second orientation, the second camera is activated. This dynamic adaptation ensures photographing accuracy is maintained across different display configurations.
2Device complexity
If a single camera is used on the rotatable display apparatus, then the device complexity is reduced, but the user must adjust their position to be captured correctly when the display orientation changes
Solution Approach 1:
Instead of using a single camera that requires user adjustment, the system segments the camera function into multiple cameras positioned at different orientations. This allows the system to maintain ease of operation by automatically selecting the appropriate camera based on display orientation, eliminating the need for users to reposition themselves.
Solution Approach 2:
The processor acts as an intermediary that monitors display orientation and automatically switches between cameras. This intermediary function bridges the gap between display orientation changes and camera selection, maintaining ease of operation without requiring direct user intervention or repositioning.
3Measurement precision
If multiple cameras with different angles of view are used, then photographing accuracy is maintained across display orientations, but the device complexity increases
Solution Approach 1:
The camera system is segmented into multiple cameras, each optimized for specific orientations. The first camera has a first angle of view suitable for the first display orientation, while the second camera has a second angle of view suitable for the second display orientation. This segmentation ensures photographing precision is maintained while managing complexity through functional specialization.
Solution Approach 2:
Each camera is designed with specific local qualities (angle of view, positioning) optimized for its intended orientation. The first camera is configured with properties suitable for capturing images when the display is in the first orientation, while the second camera has properties optimized for the second orientation. This local optimization ensures high photographing precision for each specific use case.

AI summary
A display apparatus and a control method thereof are provided. The display apparatus includes a display configured to be rotatable; a plurality of cameras; and a processor configured to: based on the display being oriented in a vertical direction, control one camera of the plurality of cameras to perform photographing; and based on a user command being received while the one camera is performing photographing, rotate the display to be oriented in a horizontal direction and control the one camera to stop photographing.
