Video Thumbnail Indexing with Face Recognition and Playback Position Highlighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in recognizing the content of video content data based on title names alone, and existing preview functions struggle to clearly link thumbnail images to the corresponding playback position, making it time-consuming to navigate long video content.
Innovation Solution
An electronic apparatus with an indexing module that extracts face images and time stamps from video content, displaying them in a list alongside a playback module that emphasizes the current playback position on the thumbnail display, allowing users to easily identify corresponding content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a list of thumbnail images is displayed to present an overview of video content, then the user can recognize video content better, but it is difficult to recognize which thumbnail corresponds to the current playback position
Solution Approach 1:
The patent applies color changes by highlighting the thumbnail image corresponding to the current playback position with a distinct color or visual emphasis. This allows users to quickly identify which thumbnail corresponds to the current playback state without confusion, resolving the contradiction between content recognition and position correspondence.
Solution Approach 2:
The patent introduces an intermediary visual indicator (such as a playback position marker or highlighted thumbnail) that mediates between the playback function and the thumbnail display. This intermediary element clearly links the current playback position to its corresponding thumbnail, solving the correspondence problem while maintaining effective content overview.
2Loss of information
If preview playback is performed to recognize video content, then content understanding is improved, but much time is required for long video content even with fast-forwarding
Solution Approach 1:
The patent segments the video content into multiple thumbnail images representing different time points or scenes. Users can scan through these segmented thumbnails to quickly understand video content without watching the entire video, significantly reducing navigation time while maintaining content comprehension.
Solution Approach 2:
The patent performs preliminary extraction and display of thumbnail images before full preview playback. Users can first review the thumbnail overview to identify interesting segments, then perform targeted preview playback only on selected portions, reducing overall time investment while improving content understanding efficiency.
3Ease of operation
If title names are appended to video content data, then content identification is simplified, but it is still difficult for users to recognize the actual content
Solution Approach 1:
The patent merges title names with thumbnail images to create a combined content identification system. Each thumbnail is associated with its corresponding title or metadata, providing both visual content preview and textual identification simultaneously. This combination overcomes the limitation of title-only identification by adding visual context while maintaining textual searchability.

AI summary
According to one embodiment, an electronic apparatus includes an indexing module, an image display processing module, a playback processing module, and a emphasizing processing module. The indexing module extracts face images which appear in a sequence of moving image data, and outputs time stamp information indicating a timing of appearance of each of the extracted face images. The image display processing module displays the extracted face images on a first display area. The playback processing module plays back the moving image data and displays the moving image data on a second display area. The emphasizing processing module emphasizes, when the moving image data is played back, a face image on the first display area, which appears within a predetermined period corresponding to a present playback position of the moving image data, based on the time stamp information corresponding to each face image which belongs to the extracted face images.
