Rotatable Display Camera Switching for Accurate User Framing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rotatable display apparatuses face challenges in accurately photographing users when the display orientation changes, as the camera's photographing direction adjusts, requiring users to reposition themselves, which is inconvenient.
Innovation Solution
A display apparatus with multiple cameras and a processor that controls camera angles based on display orientation, using a first camera for vertical orientation and a second camera with a wider angle for horizontal orientation, and adjusts camera angles using sensor data to maintain accurate user photography.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display is rotated to change orientation, then the display can provide images at various angles, but the camera's photographing direction changes accordingly causing users to be photographed incorrectly
Solution Approach 1:
The system segments the camera system into multiple cameras (first camera and second camera) with different photographing directions. The first camera is positioned to photograph when the display is in vertical orientation, while the second camera is positioned to photograph when the display is in horizontal orientation. This segmentation allows the system to maintain photographing accuracy across different display orientations without requiring users to reposition themselves.
Solution Approach 2:
The system dynamically switches between different cameras based on the display orientation. When the display rotates from vertical to horizontal orientation, the processor detects this change and switches from using the first camera to using the second camera. This dynamic adaptation ensures that the photographing direction always matches the display orientation, maintaining photographing accuracy throughout the rotation.
2Device complexity
If a single camera is used for both vertical and horizontal orientations, then the device structure is simple, but the user must reposition themselves when the display rotates
Solution Approach 1:
Instead of using a single camera that would require users to reposition, the system segments the camera function into multiple cameras positioned at different angles. The first camera is positioned for vertical display orientation, and the second camera is positioned for horizontal display orientation. This segmentation eliminates the need for users to reposition themselves when the display rotates, as the appropriate camera is automatically selected based on the display orientation.
Solution Approach 2:
The camera system achieves multi-functionality by having multiple cameras that can serve different orientation requirements. The processor universally manages both cameras and automatically selects the appropriate one based on display orientation, making the system adaptable to both vertical and horizontal orientations without requiring user intervention or repositioning.
3Device complexity
If the camera photographing direction is fixed, then the camera structure is simple, but it cannot accurately photograph users when the display orientation changes
Solution Approach 1:
The system segments the camera function into multiple fixed cameras positioned at different orientations. The first camera has a fixed photographing direction suitable for vertical display orientation, while the second camera has a fixed photographing direction suitable for horizontal display orientation. By segmenting the camera system in this way, each camera maintains a simple fixed structure while the overall system achieves the capability to accurately photograph users regardless of display orientation through automatic camera selection.

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.
