Rotating Dual-Camera Terminal for Wide-Angle Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic terminals with wide-angle lenses struggle to capture images of large objects or distant scenery effectively, as they are limited by the hardware's field of view and cannot always meet user expectations for wide-angle photography.
Innovation Solution
An electronic terminal with a rotating shaft allowing two camera bodies to change their angle, enabling the first and second cameras to obtain images that are then spliced to create a target image with a wider field of view, utilizing acceleration sensors or other angle detection methods to determine the optimal angle for image combination.

Engineering Contradiction Analysis
1Adaptability or versatility
If an independent wide-angle lens is used to achieve wide-angle mode, then the terminal apparatus supports a wider range of photography, but there are still situations where users wish to acquire an image that the wide-angle lens is not capable of capturing
Solution Approach 1:
The terminal apparatus is divided into a first body and a second body, each containing separate camera modules. The first camera captures a first image while the second camera captures a second image. By segmenting the imaging system into multiple independent camera units with different fields of view, the system can capture both wide-angle and telephoto perspectives simultaneously, resolving the limitation of a single wide-angle lens.
Solution Approach 2:
The patent introduces a new dimension of imaging capability by adding a second camera body that can be rotated relative to the first body. This creates a three-dimensional imaging architecture where cameras at different angles and positions contribute to the final composite image, enabling capture of scenes that exceed the capabilities of any single lens in the traditional two-dimensional imaging plane.
2Area of stationary object
If the angle between the first body and the second body is changed through rotation, then the field of view coverage is improved, but the device structure becomes more complex
Solution Approach 1:
The patent implements a rotating shaft mechanism that allows the second body to rotate dynamically relative to the first body, enabling the angle between them to be adjusted during operation. This dynamic adjustment capability allows the system to optimize the field of view coverage by changing the relative orientation of the two camera bodies, capturing scenes at various angles and creating composite images with extended coverage areas.
Solution Approach 2:
A rotating shaft is introduced as an intermediary mechanism between the first body and the second body. This intermediary component enables controlled relative rotation while maintaining the structural integrity of the terminal apparatus. The rotating shaft acts as a mechanical mediator that translates rotational motion into angular adjustment of the second camera body, achieving field of view expansion without requiring a completely complex reconfigurable structure.

AI summary
A terminal such as a folding-screen smartphone includes a first body and a second body; a rotating shaft coupled to the first body and the second body, and configured to change an angle between the first body and the second body through rotation of the rotating shaft. The terminal also includes a first camera in the first body configured to photograph a target object and obtain a first image in response to a photographing instruction and a second camera in the second body configured to photograph the target object and obtain a second image in response to the photographing instruction. A processing component coupled to the first body and the second body is configured to determine the angle between the first body and the second body and obtain a target image by splicing the first image and the second image according to the angle.
