Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual clipping processing for selecting a target person in video recordings is cumbersome, requiring user skills and leading to poor user experience.
Innovation Solution
A SOLO CUT mode in terminal devices that automatically generates a protagonist-centered close-up video alongside an original video, allowing users to select and switch protagonists seamlessly without manual clipping, using object identification algorithms to enhance user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual clipping processing is used to select target persons in video recordings, then the user can obtain videos of specific persons, but the operation becomes cumbersome and requires video clipping skills
Solution Approach 1:
The system automatically identifies and clips videos of target persons without requiring user intervention. The processor autonomously performs face recognition, video clipping, and thumbnail generation, allowing the system to serve itself rather than requiring the user to manually clip videos
Solution Approach 2:
The patent replaces manual mechanical clipping operations with automated computer vision algorithms. Face recognition technology and automated video processing algorithms substitute for the manual mechanical process of selecting and clipping video segments, eliminating the need for user skills in video editing
2Adaptability or versatility
If multiple cameras are configured in terminal devices to provide various shooting modes, then the shooting functionality is enhanced, but the device complexity increases
Solution Approach 1:
The processor serves multiple functions by integrating face recognition, video clipping, thumbnail generation, and video encoding capabilities into a single processing unit. This multi-functional approach allows the system to provide diverse shooting modes and post-processing capabilities without proportionally increasing device complexity
Solution Approach 2:
The patent combines face recognition, video analysis, and video clipping functions into an integrated processing pipeline. By merging these previously separate functions into a unified automated system, the device achieves enhanced versatility while managing complexity through functional integration

AI summary
This application provides a shooting method. By implementing the method, a terminal device such as a mobile phone or a tablet computer can determine a shot protagonist based on a user operation when starting shooting or in a shooting process. In the shooting process, the terminal device may display, in a preview window, an image stream collected by a camera, and the terminal device may further generate a small window that specially displays the protagonist. After recording ends, a user may obtain two videos: an original video generated based on the image stream in the preview window, and a close-up video generated based on a protagonist image stream in the small window. In this way, the user can choose to use the original video and/or the close-up video to meet personalized requirements in different scenarios at different moments of the user.
