Video Chapter Playback Using VIP Face Recognition Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording and reproducing apparatus, such as video cameras, face challenges in efficiently managing and quickly locating target scenes due to large capacities and numerous chapters, making it difficult for users to find specific scenes or chapters without extensive cueing operations, especially when scenes are long or have many chapters.
Innovation Solution
A recording and reproducing apparatus that utilizes face recognition to set importance levels for chapters based on the presence of VIPs, allowing selective reproduction of chapters with higher importance levels, thereby facilitating quick access to desired scenes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the recording medium capacity is increased to store more scenes, then the storage capability is improved, but the time required to find a target scene increases
Solution Approach 1:
The system performs preliminary face recognition and VIP detection during the recording phase, automatically tagging scenes and chapters with VIP presence information. This preliminary classification enables rapid retrieval during reproduction without requiring manual scanning of all scenes, thus resolving the contradiction between storing more scenes and quickly finding them.
Solution Approach 2:
The patent introduces face recognition technology and VIP detection as intermediary mechanisms between the raw video data and the user's search query. By detecting faces and identifying VIPs during recording, the system creates an intermediate index that mediates the search process, allowing users to quickly locate scenes containing specific people without reviewing entire scenes.
2Measurement precision
If the number of chapters in a scene is increased to provide finer granularity, then the chapter selection precision is improved, but the operation time to review all chapters increases
Solution Approach 1:
The system applies local quality by differentiating chapters based on VIP presence. Chapters containing VIPs are marked with higher priority or special indicators, allowing users to focus their review on locally significant portions rather than uniformly examining all chapters. This maintains chapter granularity while reducing review time by highlighting relevant sections.
Solution Approach 2:
The chapter management system performs self-service by automatically detecting VIPs within chapters during recording and assigning importance levels without user intervention. This automatic classification serves the user's need for rapid chapter review by pre-organizing chapters based on their content, eliminating the need for manual scanning of all chapters.
3Device complexity
If only one thumbnail image is displayed per scene, then the display simplicity is improved, but the information completeness about scene contents is reduced
Solution Approach 1:
The patent segments the scene information by detecting multiple faces/VIPs within a scene and creating separate visual indicators or metadata entries for each detected VIP. Instead of a single generic thumbnail, the system segments the scene representation to include multiple elements that convey information about different people present, thereby maintaining simplicity while improving information completeness.
Solution Approach 2:
The system adds another dimension to the thumbnail display by incorporating face detection results and VIP identification information alongside the traditional video frame thumbnail. This dimensional expansion allows the interface to present both visual content and metadata about detected persons simultaneously, enriching the information without significantly increasing complexity.

AI summary
In a recording and reproducing apparatus and a recording and reproducing method for the recording and reproducing apparatus for recording and reproducing image information on a scene obtained through photographing, relative to a predetermined first recording medium and being capable of setting one or more chapters to each scene, a face recognizing process is executed for a photographed image based on the image information, an importance level of each chapter is set in accordance with a result of the face recognizing process for a very important person (VIP) set by a user, and each chapter having a relevant importance level among importance levels of respective chapters is selectively reproduced. A user can therefore find an object chapter and scene quickly and easily.
