Camera Assembly Dynamic Frame Rate Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems installed on glass curtain walls face storage space limitations due to the large size of video signal files, which restricts the duration of data storage and efficiency of file management.
Innovation Solution
A camera assembly that adjusts frame rates based on shooting necessity, using a standard frame shooting component at M frames/s and a jump frame shooting component at N frames/s, where N<M, to record and store video data efficiently, with a memory system that stores new data and deletes outdated data, and a dynamic environment monitoring system to adjust frame rates according to environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If video data is recorded at a high frame rate (M frames/s) to ensure smooth video quality, then video quality is improved, but storage space is consumed faster and storage duration is reduced
Solution Approach 1:
The patent applies dynamic frame rate adjustment by switching between standard frame shooting component (M frames/s) and jump frame shooting component (N frames/s) based on environmental conditions. The system dynamically changes recording parameters to balance video quality and storage duration, using high frame rates only when necessary and low frame rates during normal conditions.
Solution Approach 2:
The patent changes the frame rate parameter based on shooting necessity. The standard frame shooting component records at M frames/s for high quality, while the jump frame shooting component records at N frames/s (where N<M) for extended storage duration. The system adjusts this parameter dynamically based on environmental monitoring data.
2Reliability
If video data is recorded continuously at a constant high frame rate to ensure complete coverage, then monitoring completeness is improved, but storage space is wasted during low-activity periods
Solution Approach 1:
The patent implements periodic action by dividing the recording cycle into standard frame shooting periods and jump frame shooting periods. The system periodically switches between high frame rate (M frames/s) and low frame rate (N frames/s) modes based on environmental conditions, ensuring complete monitoring coverage while reducing storage waste during low-activity periods.
Solution Approach 2:
The patent uses environmental monitoring components to provide feedback on current conditions, which then feeds back to the frame rate selection logic. Based on this feedback, the system determines whether to use standard frame shooting or jump frame shooting, optimizing storage usage while maintaining monitoring reliability.
3Device complexity
If a single frame rate mode is used for all situations, then device complexity is reduced, but adaptability to different environmental conditions deteriorates
Solution Approach 1:
The patent segments the recording function into two independent components: standard frame shooting component and jump frame shooting component. Each component is optimized for specific conditions, and the system selects the appropriate component based on environmental adaptability requirements, maintaining relatively simple device architecture while achieving high versatility.
Solution Approach 2:
The patent makes the camera system multi-functional by enabling it to operate in both standard frame mode and jump frame mode depending on environmental conditions. This universality allows a single system to adapt to various monitoring scenarios, from high-activity periods requiring smooth video to low-activity periods requiring extended storage duration.

AI summary
A camera assemble and a shooting device conveniently installed on a glass curtain wall are provided. The camera assemble includes a standard frame shooting component that is configured to record real pictures in a part of an unit time in a preset time period, a jump frame shooting component that is configured to extract a number of frames, and record real pictures at a frame rate of N frames/s for a rest of the unit time, and a frame connecting component configured to coincide a frame picture at an end of the unit of time in the preset time period with a frame picture at an initial moment of a next adjacent unit time. The present disclosure is aimed to save storage space and extend data storage duration by recording real pictures at different frame rates in different situations.
