Dual-Camera Video Capture With Pre-Switch Layout Preview
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices can only switch to dual-lens recording mode before recording, limiting flexibility and making it difficult for users to accurately predict the recording effect, as real-time preview is only shown after switching.
Innovation Solution
A method allowing flexible switching between recording modes during video recording, with options to preview the layout effects before switching, enabling accurate mode selection through interfaces displaying multiple camera combinations and layouts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic device switches to dual-lens recording mode before recording starts, then the recording mode can be changed, but the flexibility is limited and users cannot preview the layout effect before switching
Solution Approach 1:
The patent applies preliminary action by displaying the layout effect of the target recording mode on the current view-finding interface before the user completes the switching operation. This allows users to preview how the dual-lens recording will appear in the current scene before actually switching modes, enabling informed decision-making about mode selection.
Solution Approach 2:
The patent implements feedback by showing real-time layout preview of the target recording mode on the current interface. As users move or adjust the interface, the preview updates to show how the recording will look, providing continuous visual feedback that helps users accurately predict the recording effect before switching.
2Measurement precision
If the electronic device displays real-time preview after switching to dual-lens recording mode, then the recording effect can be shown to the user, but it is difficult for users to prejudge the recording effects before switching
Solution Approach 1:
The patent performs the preview action preliminarily by displaying the layout effect of the target mode on the current interface before switching is completed. This eliminates the need to wait until after switching to see the preview, allowing users to make accurate mode selections in advance and reducing unnecessary switching operations.
Solution Approach 2:
The patent skips the traditional sequential process of switching first then previewing. By showing the preview on the current interface during the switching process, it rushes through the information provision step, allowing users to see the effect immediately without the delay of completing the switch first.
3Adaptability or versatility
If the electronic device allows switching during video recording, then the flexibility is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by making the view-finding interface serve multiple functions: it acts as both the current mode display and the target mode preview simultaneously. This multi-functionality allows mode switching during recording without requiring separate preview interfaces or complex control systems, as the same interface adapts to show different information based on user interaction.
Solution Approach 2:
The patent implements dynamics by making the interface content dynamic - it can switch between showing the current mode and showing the target mode preview based on user operations. This dynamic behavior allows the system to adapt its display content in real-time, enabling flexible mode switching during recording while maintaining a relatively simple interface structure.

AI summary
Disclosed are a video capturing method and an electronic device, through which the recording mode can be flexibly switched before or during video recording, and the layout after switching can be determined before switching, thereby facilitating accurate switching. The electronic device displays a first interface (2512), where a first preview image on the first interface (2512) is displayed in a full screen layout. In response to a first operation by a user on the first interface (2512), the electronic device displays, on the first interface (2512), a first option (2513) for indicating a first layout of a second preview image and a third preview image on a view-finding interface. In response to a selection operation by the user on the first option (2513), the electronic device displays a second interface, where the second interface includes the second preview image acquired by a second camera and the third preview image acquired by a third camera; the second preview image and the third preview image are displayed in the first layout. The second camera is a front camera, and the third camera is a rear camera; or the second camera is a rear camera, and the third camera is a front camera.
