Picture Processing Apparatus Subject-Based Scene Clustering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in efficiently searching and editing moving pictures recorded on digital video cameras, as they cannot easily extract specific scenes from the chronological recording, leading to a tedious viewing experience.
Innovation Solution
A picture processing apparatus and method that acquires and clusters pictures based on identification information from devices worn by subjects, allowing users to link and reproduce scenes corresponding to specific subjects, enabling easy selection and display of desired scenes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If moving pictures are recorded chronologically on DV tape, then the recording process is simple and continuous, but users cannot easily extract and view specific scenes without watching unnecessary content
Solution Approach 1:
The system performs preliminary actions by detecting subjects and generating identification information during the picture-taking process. This allows scenes to be pre-categorized and linked to specific subjects before reproduction, enabling users to directly access desired scenes without chronological playback of unwanted content.
Solution Approach 2:
The patent introduces identification information as an intermediary element that links pictures to specific subjects. This mediator enables indirect access to scenes through subject identification rather than chronological sequence, allowing users to efficiently locate and view only relevant scenes.
2Loss of information
If diverse meta data is added to picked-up pictures, then more information is available for picture handling, but it remains difficult for general users to search for particular scenes
Solution Approach 1:
The system applies local quality by providing different types of information access for different user needs. While comprehensive meta data is maintained for information completeness, the interface presents simplified subject-based identification information for easy searching, allowing users to efficiently locate scenes without being overwhelmed by diverse meta data.
Solution Approach 2:
The patent creates a simplified copy or representation of the comprehensive meta data system. Instead of requiring users to navigate complex meta data structures, the system generates and presents identification information that copies the essential subject-linking function in an easily accessible format.
3Adaptability or versatility
If nonlinear editing is performed on personal computer, then desired scenes can be edited and written to DVD, but the procedures to capture and edit recorded moving pictures are tortuous and complicated
Solution Approach 1:
The system performs preliminary subject detection and scene linking during the picture-taking phase, before editing is needed. This preliminary organization of scenes by subject identification simplifies subsequent editing operations, allowing users to directly select and edit desired scenes without navigating complex chronological structures.
Solution Approach 2:
The patent uses identification information as an intermediary that bridges the gap between comprehensive scene data and simple user selection. This mediator enables straightforward scene selection and editing operations while maintaining the flexibility of nonlinear editing capabilities.
Data Source
AI summary
A picture processing apparatus is disclosed which processes pictures showing subjects wearing devices each assigned identification information. The picture processing apparatus includes: an acquiring mechanism acquiring a first picture sequence formed by the pictures showing the subjects wearing the devices, and a time series of the identification information assigned to the devices; and a clustering mechanism which, based on how the time series acquired by the acquiring mechanism is linked according to the identification information, links together scenes constituting the first picture sequence, the scenes having been picked up at corresponding points in time.
