Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In video surveillance scenarios, monitoring multiple videos from different cameras requires a significant workload for surveillants, making it challenging to recognize abnormalities in a timely and efficient manner.
Innovation Solution
An information processing apparatus that includes a summarizing unit to generate summary information from videos captured by multiple cameras and a display control unit to display this summary information based on predetermined conditions related to the display state of the videos.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a surveillant views all videos from multiple cameras to recognize abnormalities, then the reliability of abnormality detection is improved, but the workload and time consumption increase significantly
Solution Approach 1:
The patent extracts key information from video data through automatic analysis, generating summary screens that highlight only the most important segments. This extraction principle allows surveillants to view condensed information rather than complete videos, significantly reducing monitoring time while maintaining abnormality detection reliability.
Solution Approach 2:
The system performs preliminary automatic analysis of video content before the surveillant views it, pre-identifying important scenes and generating summary information. This preliminary processing reduces the time the surveillant needs to spend reviewing videos while ensuring abnormalities are not missed.
2Reliability
If a surveillant views all videos from multiple cameras to recognize abnormalities, then the reliability of abnormality detection is improved, but the operational complexity increases
Solution Approach 1:
The system extracts and presents only the most relevant information from multiple video streams through automatically generated summary screens. This reduces the operational complexity by filtering out unnecessary details while preserving critical abnormality information for the surveillant.
Solution Approach 2:
The patent introduces an automatic analysis system as an intermediary between the multiple video cameras and the surveillant. This intermediary processes video data, identifies important segments, and presents condensed summaries, making the monitoring operation simpler while maintaining detection reliability.
3Loss of information
If complete video information is displayed to ensure no important scenes are missed, then the information completeness is improved, but the ease of viewing multiple videos deteriorates
Solution Approach 1:
The system extracts and preserves only the most important video segments through automatic analysis, discarding redundant information. This extraction approach maintains information completeness regarding abnormalities while significantly improving the ease of viewing by reducing the total volume of video content the surveillant must review.
Solution Approach 2:
The patent applies different quality levels to different parts of the video content, providing detailed information only for important segments identified through automatic analysis, while summarizing or omitting less critical portions. This local quality differentiation maintains essential information completeness while improving overall viewing ease.
