Dual-Camera Video Recording with Drag-Based Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dual-scene video recording functions in electronic devices, such as mobile phones, lack the ability to conveniently switch between photographing modes, failing to meet diverse user requirements in complex scenes.
Innovation Solution
A video recording method that allows users to flexibly switch between single-scene and dual-scene modes through intuitive drag-and-drop operations on a viewfinder interface, enabling seamless transitions between split-screen and picture-in-picture modes using multiple cameras.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional dual-scene video recording function is used, then multiple photographed objects can be captured at once, but photographing mode cannot be conveniently switched
Solution Approach 1:
The patent implements dynamic mode switching by allowing users to drag the divider between camera views in real-time to transition between single-scene and dual-scene modes. The interface dynamically adjusts the layout and activates different camera combinations based on the user's drag operation, enabling flexible and convenient mode changes without requiring separate control menus or buttons.
2Adaptability or versatility
If multiple controls are added for mode switching, then photographing mode can be switched, but interface elements become complex
Solution Approach 1:
The patent merges the mode switching function with the existing viewfinder interface by making the divider between camera views serve dual purposes: both separating camera feeds and acting as a draggable control for mode switching. This integration eliminates the need for separate mode selection buttons or menus, reducing interface element complexity while maintaining full mode switching capability.
Solution Approach 2:
The divider element in the viewfinder interface is designed with multi-functionality, serving both as a visual separator between camera feeds and as an interactive control for mode switching. This universal design allows a single interface element to perform multiple functions, avoiding the addition of separate controls and maintaining interface simplicity.
3Adaptability or versatility
If drag-and-drop operation is implemented, then mode switching becomes flexible, but user operation becomes more complex
Solution Approach 1:
The patent segments the viewfinder interface into multiple draggable regions, including the divider between camera views and potentially the camera feeds themselves. This segmentation allows users to interact with specific portions of the interface to trigger mode changes, making the drag operation more intuitive and easier to perform while maintaining flexible mode switching capability.

AI summary
A video recording method, which comprises: displaying a first interface, where the first interface includes a first image captured by a first camera, and the first image is displayed in a full-screen mode on the first interface; displaying a first control on the first interface in response to a first operation performed by a user on a first edge of the first interface; displaying a second interface in response to a first drag-and-drop operation performed by the user on the first control, where on the second interface, a first location of the first control and a size of the first window change with a real-time touch location of the first drag-and-drop operation; displaying a third interface in response to an end of the first drag-and-drop operation, where the third interface includes a second image captured by the first camera and a third image captured by a second camera.
