Action-Based Video Frame Processing for Slow-Motion Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ordinary users find it difficult to control slow-motion or fast-motion shooting technologies, resulting in suboptimal video quality due to the inability to use advanced capabilities like DCG and PDAF at high frame rates.
Innovation Solution
An electronic device automatically generates slow-motion or fast-motion videos by processing video frames to match shooting and playing frame rates, enabling frame interpolation or extraction based on detected specified actions, while maintaining audio synchronization and quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the shooting frame rate is set to be greater than the playing frame rate to achieve slow-motion effect, then the viewing feeling is improved, but the device complexity increases and advanced capabilities like DCG and PDAF cannot be utilized
Solution Approach 1:
The patent segments the video into multiple parts based on action detection, applying different frame rate processing strategies to different segments. The video is divided into first video part (with specified action) and second video part (without specified action), allowing selective slow-motion or fast-motion processing only where needed, while maintaining normal frame rate processing elsewhere.
Solution Approach 2:
The patent performs preliminary action by detecting specified actions in the video before applying frame rate processing. The system first identifies which parts of the video contain specified actions, then applies appropriate processing (slow-motion or fast-motion) to those identified segments, avoiding unnecessary processing in other segments.
2Measurement precision
If manual operation is required to control slow-motion or fast-motion shooting, then the control precision is improved, but the ease of operation deteriorates for ordinary users
Solution Approach 1:
The patent implements self-service by having the system automatically detect specified actions and apply appropriate frame rate processing without requiring manual user input. The system autonomously identifies which video segments need slow-motion or fast-motion processing based on action detection, eliminating the need for users to manually control the process while maintaining accurate action identification.
3Manufacturing precision
If the shooting frame rate is set to match the playing frame rate, then the video quality is improved through advanced capabilities, but the slow-motion or fast-motion effect is lost
Solution Approach 1:
The patent applies dynamics by adjusting the frame rate processing dynamically based on the detected actions in different video segments. The system changes the processing approach (slow-motion, fast-motion, or normal speed) according to the content of each segment, allowing the video to adapt its playback characteristics to express different emotions and maintain both quality and effect.
Solution Approach 2:
The patent applies local quality by applying different frame rate processing strategies to different local segments of the video. The first video part (with specified action) receives different processing than the second video part (without specified action), allowing each segment to have optimized processing that matches its content and emotional expression needs.
4Ease of operation
If frame interpolation or extraction is performed to achieve slow-motion or fast-motion effect, then the viewing feeling is improved, but the processing time increases
Solution Approach 1:
The patent applies partial action by performing frame interpolation or extraction only on the necessary segments (first video part with specified actions) rather than processing the entire video uniformly. This selective processing reduces the overall processing time while still achieving the desired slow-motion or fast-motion effects in the critical segments that need emotional expression.

AI summary
Embodiments of this application provide a video processing method and an electronic device, and relate to the field of terminal technologies. When recording a video, the electronic device collects image frames based on a first frame rate, and generates an original video file; automatically performs frame interpolation or frame extraction processing on image frames in the original video file that include a specified action; and plays a processed video file based on the first frame rate.
