Spherical Thumbnail Display for Moving Image Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems struggle to effectively navigate and display large amounts of images captured during movement, such as those from vehicle cameras, making it difficult for viewers to identify specific scenes within the data.
Innovation Solution
A display control device and method that acquires and arranges thumbnails of images in a predetermined direction based on image-capturing time-series order, while displaying them side by side in a direction different from the predetermined direction, and maps 360-degree images onto the outer surfaces of spherical display areas in a virtual three-dimensional space, allowing rotation to change the angle of display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If thumbnail images are displayed side by side in a matrix form, then the display density is improved, but the distinguishability of individual thumbnails deteriorates
Solution Approach 1:
The patent transitions from a two-dimensional matrix arrangement to a three-dimensional spherical arrangement of thumbnails. By mapping thumbnails onto the surface of a sphere in virtual 3D space, the system maintains high display density while providing natural depth-based separation and spatial organization that enhances distinguishability. The spherical geometry allows thumbnails to be distributed across multiple curved surfaces rather than competing in a flat grid.
2Duration of action of moving object
If images are captured for a long period of time, then the completeness of recorded scenes is improved, but the data management difficulty increases
Solution Approach 1:
The patent segments the large volume of captured images by organizing them into distinct temporal groups (morning, afternoon, evening sessions) and spatial locations. Each session's thumbnails are separately arranged on different spherical display areas, breaking down the management of long-duration capture data into manageable, independently navigable units rather than a single overwhelming dataset.
Solution Approach 2:
By arranging thumbnails in a three-dimensional spherical space rather than a flat structure, the patent adds spatial and depth dimensions to data organization. This 3D arrangement allows intuitive navigation through time-series data by rotating and zooming the spherical display, making long-duration captured data more manageable and searchable without increasing system complexity.

AI summary
From captured images, a scene desired by a viewer is appropriately detected. A display control device includes: an image information acquisition unit 60 that acquires information on a plurality of images captured during movement; a set time designation unit 66 that designates a plurality of set times based on the information on images; a thumbnail acquisition unit 68 that acquires the images captured at the set times as thumbnails; and a display image generation unit 70 that generates a display image to be displayed on a display unit so that the plurality of acquired thumbnails are arrayed in a predetermined direction in image-capturing time-series order while being displayed side by side in a direction different from the predetermined direction based on position information indicating positions at which the images are captured.
