Flexible Display Camera Preview Range Control for Screen Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The physical movement of cameras in flexible electronic devices due to changes in display area size can deteriorate camera usability and user experience, leading to discontinuous switches in preview screens.
Innovation Solution
An electronic device with a flexible display and a camera that includes a lens assembly moving with the display, equipped with a processor to detect the display's movement and adjust the preview range in captured images accordingly, ensuring continuous preview screen display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the flexible display changes size (extends or contracts), then the display area is increased or reduced, but the camera position changes causing discontinuous preview screens
Solution Approach 1:
The camera lens assembly is configured to move in connection with the flexible display, dynamically adjusting its position as the display extends or contracts. This dynamic positioning maintains the camera's relative position throughout the transformation, preventing discontinuous preview screen switches while allowing the display area to change size.
2Adaptability or versatility
If the camera moves with the flexible display, then the display area can change size, but camera usability deteriorates due to view angle changes
Solution Approach 1:
The processor detects the movement of the flexible display through sensors and uses this feedback information to adjust the preview range in the captured image. By monitoring the display's extension or contraction state, the system dynamically compensates for camera position changes, maintaining consistent camera usability across different display sizes.
Solution Approach 2:
The system changes the preview range parameter in the captured image based on the flexible display's movement state. When the display extends or contracts, the processor adjusts the preview range to compensate for the resulting view angle changes, maintaining consistent camera operation across different display configurations.
3Adaptability or versatility
If the camera position changes with display movement, then the display can be flexible, but the preview screen switches discontinuously
Solution Approach 1:
The processor continuously monitors the flexible display's movement through sensors and uses this real-time feedback to adjust the preview range. This closed-loop control ensures that the preview screen remains continuous and stable throughout the display's extension or contraction, preventing discontinuous switches while maintaining flexible display capability.

AI summary
An electronic device and a preview control method thereof are provided. The electronic device includes a flexible display, a camera including a lens assembly that moves in conjunction with the movement of the flexible display, and a processor. The processor can detect the movement of the flexible display through a sensor and can adjust a preset preview range on the basis of the detected movement of the flexible display. The processor can adjust a preview range in consideration of the movement of the flexible display, the preview range being a preview range in a captured image acquired through the camera or a preview range in a region captured by an image sensor. A preview image corresponding to the adjusted preview range can be displayed through the flexible display.
