Dynamic Sensor Configuration Switching for Video Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Capturing high-quality video at high frame rates and resolutions is resource-intensive, and users may forget to activate high frame rate capturing or activate it too late, leading to missed fast movements in scenes.
Innovation Solution
A method and device that dynamically adapt video capturing by switching between image sensor configurations, capturing video data at different frame rates and resolutions, with a lower resolution and higher frame rate used for motion detection, and switching to a higher resolution and frame rate when fast motion is detected, allowing for efficient generation of slow motion videos.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If video is captured at high frame rates and high resolutions, then video quality is improved, but resource usage (energy consumption and memory) increases
Solution Approach 1:
The system dynamically switches between different image sensor configurations based on detected motion levels. When fast motion is detected, the system activates a first configuration optimized for high frame rate capture; when motion is slow, it switches to a second configuration optimized for energy efficiency. This dynamic adaptation resolves the contradiction by adjusting resource usage according to actual capture needs rather than operating at maximum capacity continuously.
Solution Approach 2:
The patent changes operational parameters (frame rate, resolution, sensor configuration) based on motion detection results. The system monitors motion in captured video and adjusts the image sensor configuration parameters accordingly - increasing frame rate when motion is detected and reducing it when motion is minimal. This parameter adaptation allows the system to maintain video quality when needed while minimizing energy consumption during normal conditions.
2Ease of operation
If manual activation of high frame rate capturing is implemented, then user control is improved, but reliability decreases due to user error or delayed activation
Solution Approach 1:
The system incorporates automatic motion detection feedback that monitors captured video for fast motion events. When motion exceeding a threshold is detected, the system automatically triggers high frame rate capture without requiring user intervention. This feedback mechanism ensures reliable capture of unexpected events while allowing users to maintain manual control when desired, thus resolving the contradiction between ease of operation and reliability.
Solution Approach 2:
The system performs self-monitoring and self-adjustment by automatically detecting motion events and switching sensor configurations without user input. The motion detection algorithm autonomously determines when high frame rate capture is necessary and activates the appropriate sensor configuration, making the system self-sufficient for capturing critical moments while preserving user control capabilities.
3Reliability
If high frame rate capturing is activated continuously, then capture reliability is improved, but resource usage increases
Solution Approach 1:
Instead of continuous high frame rate operation, the system employs periodic motion detection checks at lower frame rates and only activates high frame rate capture when motion events are detected. This periodic monitoring approach maintains capture reliability by ensuring fast motion events are detected and captured while significantly reducing average resource usage compared to continuous high frame rate operation.

AI summary
On the basis of a first configuration of one or more image sensors (110, 110'; 112), first video data is captured at a first frame rate and a first resolution and second video data is captured at a second frame rate and a second resolution. The second frame rate is higher than the first frame rate and the second resolution is lower than the first resolution. Further, an amount of motion is detected in the captured second video data. On the basis of the detected amount of motion, the at least one image sensor (110, 110'; 112) is switched to a second configuration. On the basis of the second configuration, third video data is captured at a third frame rate and a third resolution. The third frame rate is higher than the first frame rate and the third resolution is higher than the second resolution.
