Thumbnail-Based Moving Picture Editing Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for setting edit points in moving picture data are cumbersome and difficult to use, requiring repeated operations with play, search, and pause buttons to accurately position desired edit points, leading to impractical and undesired results.
Innovation Solution
A moving picture data editing device with a command input unit, storage unit, decoder, thumbnail generator, and display image generation/output unit that allows users to easily set IN and OUT points by displaying thumbnails of the moving picture data, enabling precise selection of edit points through intuitive operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional play/search/pause button operations are used to set edit points, then the system can function with basic controls, but the ease of operation deteriorates and editing precision is insufficient
Solution Approach 1:
The video timeline is segmented into discrete thumbnail images that can be individually selected. Instead of continuously scrolling through video content, the system divides the video into manageable visual segments (thumbnails) that represent specific time points, allowing users to precisely locate and select edit points by clicking on desired thumbnail images.
Solution Approach 2:
The system generates thumbnail copies of the video content at regular intervals. These thumbnails serve as visual representations that can be displayed and selected without requiring the user to watch the entire video continuously. The thumbnails act as simplified copies that preserve the essential visual information needed for edit point selection.
2Measurement precision
If repeated play/search/pause operations are performed to locate exact edit points, then the system can achieve precise positioning, but the time required for editing increases significantly
Solution Approach 1:
The system performs preliminary action by automatically generating and displaying thumbnail images representing various time points in the video before the user needs to set edit points. This pre-computed visual index allows users to immediately locate desired edit points without performing repeated play/search/pause operations, significantly reducing the time required for editing while maintaining precision.
3Loss of information
If the entire video content is displayed continuously, then the user can view all content, but the user interface complexity and difficulty of locating specific portions increases
Solution Approach 1:
The system adds a spatial dimension to video navigation by displaying thumbnails in a scrollable list or grid layout alongside or instead of continuous video playback. This transforms the one-dimensional time-based navigation into a two-dimensional interface where users can visually scan and jump to specific time points, making the interface more manageable and easier to navigate despite the increased information density.
Data Source
AI summary
When a predetermined operation is made of a remote commander while moving picture data read from a storage unit and decoded is being displayed on a display screen, a thumbnail of a reproduced image being displayed on the display screen and a plurality of thumbnails near the reproduced image displayed on the display screen are displayed being superposed on the reproduced image. Information on edit points indicating the position of image data corresponding to ones, designated by the remote commander, of the plurality of thumbnails displayed on the display screen is added to the moving picture data, and the data is stored into the storage unit. Thus, it is possible to set IN and OUT points as edit points elaborately and easily for edition of moving picture data.
