Face Image Thumbnail Menu for Video Dubbing Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information recording and reproducing systems lack convenience when users need to select and manage multiple characters or individuals in video content during dubbing processes.
Innovation Solution
A method that recognizes face images from video information, displays them on a screen, allows user selection, and registers these images as thumbnail images for easy navigation and dubbing between recording media, enhancing user convenience by using face information for dubbing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a menu screen is created to display characters and their positions in video content, then users can select and manage multiple individuals during dubbing, but the operation complexity and time required increase
Solution Approach 1:
The patent creates thumbnail images that are copies or representations of the original video frames containing face images. These thumbnails serve as simplified proxies for the full video content, allowing users to select characters and scenes without navigating through the entire video. The thumbnail copying mechanism enables efficient character selection while maintaining ease of operation.
Solution Approach 2:
The patent segments the video content by extracting and displaying individual face images and their corresponding thumbnail images in a menu screen. This segmentation allows users to view and select specific characters and scenes separately rather than navigating through the complete video sequence, thereby improving operational efficiency while maintaining versatility.
2Productivity
If face images are extracted and displayed in a menu screen for dubbing selection, then character management becomes more efficient, but the processing time and computational resources increase
Solution Approach 1:
The patent performs preliminary action by extracting and storing face images and their corresponding thumbnail images before the actual dubbing process. The menu screen is pre-populated with these extracted images, so when users need to select characters for dubbing, the work has already been done. This preliminary extraction and organization of face images significantly reduces the time required during the actual dubbing operation.
Solution Approach 2:
The patent creates thumbnail copies of video frames containing face images and stores them for quick access. These pre-generated thumbnail images serve as ready-to-use representations that eliminate the need for real-time image processing during dubbing selection, thereby improving productivity while minimizing additional processing time.
3Ease of operation
If thumbnail images are created from registered face images, then navigation and selection become easier, but the memory requirements and data storage increase
Solution Approach 1:
The patent applies local quality by creating thumbnail images with reduced resolution and size compared to the original video frames. The thumbnails retain the essential visual information needed for character identification and scene recognition but use significantly less storage space. This local quality adjustment optimizes the balance between navigation convenience and data storage requirements.
Data Source
AI summary
A signal processing portion successively accepts frames of images from video information recorded on a recording medium acting as a dubbing source. The medium is one of a hard disc drive and a disc medium. Then, the processing portion recognizes face images from the frames of image, displays the recognized face images on the screen of an LCD, registers face images selected from the displayed face images in response to a manipulation of control buttons, creates thumbnail images from images which are included in the registered face images and which have appeared at ratios in excess of 70%, extracts images including the thumbnail images from the recording medium acting as the dubbing source, and dubs the extracted images onto the recording medium acting as a dubbing destination.
