Foldable Display Panoramic Imaging via Dual Camera Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with foldable displays face challenges in generating panoramic images efficiently due to the need for multiple images to be obtained while the device is being carried, often resulting in blurred images due to user hand movement.
Innovation Solution
An electronic device with a foldable display incorporating multiple cameras and a hinge unit, where a processor coordinates image capture and stitching across the cameras, detects rotation, and adjusts settings to minimize blurring and optimize image overlap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple images are obtained sequentially using one camera while the device is being carried, then a panoramic image can be generated, but the images may be blurred due to user hand movement
Solution Approach 1:
The patent divides the panoramic image capture task into multiple simultaneous image acquisitions using separate cameras positioned at different locations within the foldable device. Each camera captures a portion of the panoramic scene concurrently, eliminating the need for sequential capture and reducing motion blur from hand movement during the capture process.
Solution Approach 2:
The patent combines multiple cameras within a single foldable device to achieve panoramic capture capabilities. By merging the functionality of multiple cameras and coordinating their simultaneous operation, the system achieves high-quality panoramic images without the time loss associated with sequential single-camera capture.
2Productivity
If multiple cameras are used to capture images simultaneously, then image quality improves and capture time is reduced, but device complexity increases
Solution Approach 1:
The patent implements a foldable display device that serves multiple functions: it operates as a regular display device when closed and transforms into a panoramic camera system when unfolded. This multi-functionality allows the same physical device to provide both standard display capabilities and advanced panoramic imaging without requiring entirely separate dedicated equipment.
Solution Approach 2:
The patent utilizes the dynamic folding and unfolding motion of the display device to change the spatial relationship between cameras and capture different panoramic views. The hinge mechanism enables dynamic reconfiguration of the camera array, allowing the system to adapt its geometry for optimal panoramic capture while maintaining a compact form when not in use.
