Dynamic Time-Lapse Frame Rate Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing time-lapse video generation methods often result in inconsistent playback speeds, with certain segments being sped up too much or too little, leading to an uneven viewing experience.
Innovation Solution
A system that dynamically adjusts the time-lapse video frame rate in response to triggers, such as user interactions or changes in image capture device motion, allowing for seamless transitions between different playback speeds within a single video without interrupting the generation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single fixed frame rate is used for generating time-lapse video frames, then the generation process is simple and consistent, but the playback speed becomes uneven with some segments sped up too much or too little
Solution Approach 1:
The patent applies dynamics by transitioning from a fixed frame rate to a dynamic frame rate system that can adjust the time-lapse video frame rate during generation. The system detects trigger events (such as user input or motion thresholds) and modifies the frame rate accordingly, allowing different segments of the video to have different playback speeds while maintaining overall consistency and quality.
2Manufacturing precision
If the time-lapse video frame rate is changed during generation to improve playback consistency, then the video quality improves, but the generation process may be interrupted
Solution Approach 1:
The patent applies preliminary action by detecting trigger events before they occur or at the moment they occur, and proactively adjusting the frame rate in anticipation of or in response to these events. This allows the system to maintain generation continuity while still achieving the desired playback speed consistency, as the frame rate changes are triggered by predetermined conditions rather than arbitrary interruptions.
3Adaptability or versatility
If dynamic frame rate adjustment is implemented, then the time-lapse video becomes more engaging and visually stable, but the system complexity increases
Solution Approach 1:
The patent applies local quality by implementing frame rate adjustments in specific local segments of the video based on trigger events, rather than uniformly across the entire video. This allows the system to maintain simplicity in non-triggered segments while providing enhanced adaptability and visual stability only where needed, optimizing the balance between complexity and performance.

AI summary
An image capture device continuously generates time-lapse video frames to be included within a time-lapse video using a dynamic time-lapse video frame rate, with the value of the dynamic time-lapse video frame rate changing based on activation of a trigger to change the dynamic time-lapse video frame rate. The dynamic time-lapse video frame rate alternates between different values.
