Wide-View Display Segmentation for Comparing Same Locations Over Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wide-view images displayed on communication terminals often appear curved, causing confusion and making it difficult for users to compare current and previous images of the same location, especially when different predetermined areas are displayed.
Innovation Solution
A display terminal and communication system that includes circuitry to display first and second predetermined-area images representing the same location captured at different times, allowing for accurate comparison and understanding of changes over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wide-view images are displayed to provide comprehensive viewing coverage, then the viewing angle and imaging range are improved, but the images appear curved and cause user confusion
Solution Approach 1:
The patent divides the wide-view image into a normal-angle-of-view image (first image) and a peripheral-angle-of-view image (second image). This segmentation allows the central important area to be displayed in a familiar rectangular format while the peripheral areas are shown in a curved format, resolving the contradiction between wide viewing coverage and user comprehension.
2Area of stationary object
If different predetermined-area images are displayed for current and previous images captured at the same location, then the imaging range is expanded, but the images become difficult to compare
Solution Approach 1:
The patent applies different display qualities to different parts of the image. The first image (normal angle of view) is displayed with rectangular geometry suitable for comparison, while the second image (peripheral angle of view) maintains the curved wide-view characteristics. This local quality differentiation enables accurate comparison of the same location while preserving the benefits of wide imaging range.

AI summary
A display terminal comprising circuitry that displays a first predetermined-area image on a display screen, the first predetermined-area image representing a predetermined area in a first wide-view image having been captured at a given location on a first date and time; and displays a second predetermined-area image on the display screen, the second predetermined-area image being related to the predetermined area in a second wide-view image, the second wide-view image having captured at the given location on a second date and time different from the first date and time.
