Face Image Extraction for Video File Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in recognizing and managing video data files with related content, as existing systems require time-consuming playback or fast-forward operations to identify content, especially when multiple files are created intermittently during video recording.
Innovation Solution
An electronic apparatus with a face image extraction module, display control module, and file processing module that extracts and displays face images from video data files, allowing users to select and merge relevant files based on face image thumbnails and timestamps, facilitating content recognition and editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video data files are created intermittently during recording, then recording flexibility is improved, but difficulty in recognizing content increases
Solution Approach 1:
The patent extracts face images from video data files as representative indices. Instead of requiring users to playback entire videos to recognize content, the system extracts and displays only the face image thumbnails that represent each video file's content, enabling quick identification without playing the full video.
Solution Approach 2:
The patent creates a visual copy of video content through face image thumbnails. These thumbnails serve as representatives or copies of the actual video content, allowing users to recognize and identify video files based on these simplified visual representations rather than viewing the complete video data.
2Measurement precision
If face image extraction is performed for all video data files, then content recognition accuracy is improved, but processing time increases
Solution Approach 1:
The system extracts only the most relevant visual information (face images) from each video file rather than processing every frame or requiring full playback. This selective extraction maintains recognition accuracy while significantly reducing processing time and computational resources required.
Solution Approach 2:
The patent performs face image extraction and thumbnail generation as preliminary processing steps before user interaction. By pre-processing and indexing the video files with representative face images, the system enables fast search and identification operations without requiring time-consuming full video analysis during user queries.
3Adaptability or versatility
If multiple video data files with related content are created, then recording flexibility is improved, but time required for playback increases
Solution Approach 1:
The patent extracts face image thumbnails as representative indices from multiple video files. Users can quickly identify and select specific video files or groups of related files by viewing these thumbnails, enabling rapid navigation and selection without requiring sequential playback through all files.
Solution Approach 2:
The face image thumbnails serve as an intermediary between the user and the actual video files. Instead of directly interacting with multiple video files through lengthy playback operations, users interact with the simplified thumbnail interface, which mediates the selection process and enables quick access to desired content.
Data Source
AI summary
According to one embodiment, an electronic apparatus includes an image extraction module, a display control module, and a file processing module. The image extraction module extracts face images including a plurality of face images of persons in a video obtained by playing back a video data file from each of video data files. The display control module displays a selection screen which allows a user to select one or more video data files from the video data files, and displays the extracted face images on the selection screen to lay out the face images in correspondence with the video data files. The file processing module executes a process for the one or more video data files selected on the selection screen.
