Focus-Tracking Video Recording With Floating Multi-Window Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual editing of videos recorded by terminal devices with multiple cameras is complex and requires specific technical skills, leading to a poor user experience.
Innovation Solution
A recording method and apparatus that utilizes a terminal device with a first and second window interface, where the second window floats on top of the first, allowing for focus tracking of an object and automatic adjustments in video recording based on object presence, reducing manual editing needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual editing processing is used to obtain video of target character, then video editing can be performed, but the operations become complex and require specific video editing techniques
Solution Approach 1:
The terminal device automatically performs video editing functions including focus tracking, automatic cropping, and multi-window composition without requiring user intervention. The system detects target objects in real-time and autonomously generates edited video content, making the device serve itself rather than requiring manual user editing operations.
Solution Approach 2:
The system performs preliminary video processing during the recording phase by pre-identifying target objects, pre-cropping relevant frames, and pre-composing multi-window layouts. This preliminary action ensures that when video playback or sharing is needed, the edited content is already prepared, eliminating the need for post-recording manual editing.
2Productivity
If focus tracking is implemented to automatically capture target object, then editing operations are reduced, but the system complexity increases
Solution Approach 1:
The video processing system is segmented into independent functional modules including object detection module, focus tracking module, automatic cropping module, and multi-window composition module. Each module handles a specific task independently, which simplifies the overall system architecture while maintaining high automation capabilities for focus tracking and reduced editing operations.
3Adaptability or versatility
If multiple windows are used to display different pictures, then more subjects can be captured, but the interface complexity increases
Solution Approach 1:
The interface employs a nested window structure where a second window (showing focused target object) is positioned over a first window (showing overall scene). This nesting arrangement allows multiple viewing perspectives simultaneously while maintaining a clean, organized interface layout that doesn't overwhelm the user despite the increased functionality.

AI summary
Embodiments of this application provide a recording method and apparatus, and a storage medium, which are applied to a terminal device. The method includes: displaying a first interface of a camera application; at a first moment, when detecting that a first position of a first picture includes a first object, including the first object in a second picture; at a second moment, when detecting that a second position of the first picture includes the first object, including the first object in the second picture; at a third moment, when detecting that the first picture does not include the first object, skipping including the first object in the second picture as well; at a first moment, when detecting that a third position of the first picture includes the first object, including the first object in the second picture; and at a fifth moment, when detecting that a fourth position of the first picture includes the first object, including the first object in the second picture. In this way, by setting a focus tracking object, the terminal device can additionally obtain one or more focus tracking videos corresponding to the focus tracking object during video recording, thereby improving the recording experience of a user.
