Video Sharing System with Subject Identification for Event Photography
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video sharing systems are inconvenient for users to browse through videos shot by multiple photographers within the same facility, as users need to replay each video to identify content, and are not suitable for specific photography scenarios like capturing a specific subject at events.
Innovation Solution
A video sharing system that includes cameras, a video collection unit, photographic subject identification, and accumulation units, along with position identification and transmission units, to collect, identify, and accumulate videos, allowing users to easily access and edit videos of specific subjects, and provide photography support by indicating the location of subjects within the camera's range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If videos are collected from multiple cameras without subject identification, then the quantity of videos increases, but the ease of operation deteriorates as users must replay each video to identify content
Solution Approach 1:
The system performs preliminary identification of photographic subjects in videos before users access them. The photographic subject identification unit automatically detects and identifies subjects in advance, storing this information for later retrieval. This eliminates the need for users to replay videos to identify content, resolving the contradiction between having multiple videos and easy browsing.
Solution Approach 2:
The patent introduces photographic subject information as an intermediary between the video content and users. Instead of directly interacting with raw video files, users query the system through subject identifiers (names, positions, attributes). This intermediary layer enables efficient access to specific videos without manual browsing, solving the ease of operation problem while maintaining video quantity.
2Productivity
If automatic photography systems detect subjects automatically, then productivity increases, but adaptability deteriorates for specific photography scenarios like capturing a specific child at a sports meeting
Solution Approach 1:
The system dynamically adjusts between automatic and manual photography modes based on user needs. Photographers can register specific photographic subjects (e.g., their own children) and the system adapts by prioritizing detection and notification for these registered subjects. This dynamic adaptability maintains automatic photography productivity while enabling customization for specific scenarios.
Solution Approach 2:
The patent applies local quality by allowing different photography behaviors for different subjects. Registered subjects receive special treatment with targeted notifications and priority capture, while other subjects follow general automatic detection rules. This localized customization enables the system to handle specific photography scenarios (like capturing a particular child) without sacrificing overall automatic photography productivity.
3Measurement precision
If position identification is implemented to identify subject locations, then measurement precision improves, but device complexity increases due to additional transmission units and reception units
Solution Approach 1:
The transmission units and reception units serve multiple functions: they identify positions of photographic subjects, track camera locations, and provide spatial context for video organization. This multi-functionality justifies the added device complexity by delivering comprehensive position information that enhances video sharing capabilities beyond simple location tracking.
