Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for displaying thumbnails of wide-angle panorama images struggle with image distortion and tilt deviation, making it difficult to visually recognize the images effectively.
Innovation Solution
An information processing apparatus is designed with an image correction unit that generates correction information to address distortion and tilt in wide-angle panorama images, allowing for improved visibility through scrolling and display of corrected thumbnail images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a thumbnail of a wide-angle panorama image is displayed in a standard aspect ratio area (3:4 or 9:16), then the thumbnail can be displayed in the designated display area, but the image becomes difficult to visually recognize due to high reduction ratio and distortion
Solution Approach 1:
The patent transforms the 2D thumbnail display problem into a 3D solution by generating a three-dimensional thumbnail image from the wide-angle panorama image. This 3D thumbnail can be rotated and viewed from multiple angles, allowing the entire panorama content to be displayed without being constrained by the limited 2D display area aspect ratio, thereby maintaining image visibility while adapting to standard display areas
Solution Approach 2:
The patent segments the wide-angle panorama image into multiple regions and processes each region separately to correct distortion and tilt deviation. By dividing the image into manageable segments and applying correction algorithms to each, the system maintains image quality and visibility while adapting to the constrained thumbnail display area
2Ease of operation
If a panoramic image is scrolled and displayed in a display area, then the image can be viewed, but image distortion in peripheral portions is not corrected making it difficult to discriminate what is photographed
Solution Approach 1:
The patent applies distortion correction and tilt deviation correction algorithms to the panoramic image before it is displayed or scrolled. By pre-processing the image to correct geometric distortions in peripheral regions, the system ensures that the corrected image maintains accurate spatial relationships and visual clarity throughout the entire image area, enabling easy viewing and accurate discrimination of photographed content
Solution Approach 2:
The patent replaces manual image manipulation with automated image processing algorithms that detect and correct distortion and tilt deviations. The system uses computational methods to analyze the panoramic image structure, identify distortion patterns, and apply mathematical transformations to correct geometric inaccuracies, substituting mechanical viewing adjustments with intelligent automated correction
3Measurement precision
If a cut-out image obtained by correcting distortion of a thumbnail is displayed, then specific photographic subjects become clearer, but the whole wide-angle image cannot be visually recognized in every corner
Solution Approach 1:
The patent creates a 3D thumbnail that encapsulates the entire wide-angle panorama, allowing users to view the complete image area by rotating the three-dimensional representation. This approach maintains all corners of the original wide-angle image accessible while providing corrected views of specific regions, solving the contradiction between showing the whole image and providing distortion-corrected detail

AI summary
When thumbnails of a wide-angle panorama image are displayed, by scrolling and displaying a thumbnail image in which distortion and tilt deviation are reduced, visibility is improved. An information processing apparatus includes an image correction information generating unit, a control unit, and a display unit. The image correction information generating unit is composed of an image distortion determination processing unit and a horizontal/vertical direction determination processing unit, and generate correction information for correcting a partial image composed of an arbitrary image area of the wide-angle panorama image. The control unit corrects the partial image on a basis of the correction information generated by the image correction information generating unit. The display unit 108 displays an image. Then, the control unit causes the display unit to display the corrected partial image as the thumbnail image.
