Dual Thumbnail Array Scene Navigation for Moving Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for selecting and accessing specific scenes in moving images are inefficient, as they require playing the entire video to find a desired scene, and thumbnail images lack sufficient information to accurately represent the content.
Innovation Solution
An information processor and method that extracts frame data from moving images based on predetermined rules, decodes it, and displays multiple thumbnail arrays aligned in chronological order, allowing users to easily comprehend the content and access desired scenes efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a single thumbnail array is displayed, then the device complexity is low, but the information quantity provided to the user is insufficient
Solution Approach 1:
The patent divides the moving image into multiple segments by extracting frames according to different rules (e.g., different time intervals, different scene types). Each rule generates a separate thumbnail array, allowing users to view the same moving image content through multiple organizational perspectives simultaneously, thereby increasing information quantity without requiring a single complex display system
Solution Approach 2:
The patent adds a new dimension to the thumbnail display by organizing frames according to multiple different rules simultaneously. Instead of a single linear sequence, multiple thumbnail arrays are displayed in parallel, each representing a different dimension of organization (time-based, scene-based, etc.), enabling users to comprehend the moving image content more comprehensively
2Loss of information
If the entire moving image is played to understand the content, then complete information is obtained, but the time consumption is excessive
Solution Approach 1:
The patent performs preliminary action by extracting and displaying key frames as thumbnails before the user watches the entire moving image. Multiple thumbnail arrays provide advance information about different aspects of the content (overall progression, scene changes, etc.), allowing users to form a preliminary understanding and selectively watch only relevant portions, thereby reducing time consumption while maintaining content comprehension
Solution Approach 2:
Instead of requiring users to view the entire moving image (excessive action), the patent provides multiple partial views through different thumbnail arrays. Each array shows a partial but informative representation of the content from a different organizational perspective, allowing users to obtain sufficient understanding through selective sampling rather than complete viewing
3Ease of operation
If frame data is extracted according to multiple rules and displayed as multiple thumbnail arrays, then the user can easily comprehend the moving image content and accurately select desired scenes, but the processing complexity and time required increase
Solution Approach 1:
The system performs frame extraction according to multiple rules in advance, before the user needs to select a scene. Multiple thumbnail arrays are prepared and displayed ready for interaction, allowing users to immediately comprehend the content structure and select desired scenes without waiting for processing during interaction, thereby improving ease of operation while managing processing time through advance preparation
Data Source
AI summary
A thumbnail display screen is displayed. The thumbnail display screen contains a first thumbnail array and a second thumbnail array, in which the images of two groups of frames extracted from a moving image file according to different rules are aligned in the order of appearance in the moving image. The first thumbnail array can be shifted forward or backward via an input apparatus, and the second thumbnail array is shifted in conjunction with a shift of the first thumbnail array. When one of the frames on the thumbnail display screen is selected, the moving image is played from the selected frame or the nearest scene switching point from the frame.
