Display Terminal Wide-View Image Alignment for Time-Based Comparison
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 main display area showing a first predetermined area and a sub-display area showing a second predetermined area. This segmentation allows the curved wide-view image to be broken into manageable portions, with the main area providing the comprehensive view and the sub-area providing a corrected reference view for comparison, thereby resolving the contradiction between wide viewing angle and user comprehension.
Solution Approach 2:
The patent introduces a predetermined-area image as an intermediary element that represents a specific area of the wide-view image in a corrected, non-curved format. This intermediary serves as a reference that helps users understand and compare specific locations within the curved wide-view image, bridging the gap between the comprehensive but distorted wide-view display and the user's need for accurate spatial understanding.
2Reliability
If different predetermined areas are displayed for current and previous images, then each image shows its captured area, but comparison between images becomes difficult
Solution Approach 1:
The patent creates a common reference frame by displaying the second predetermined area (from the previous wide-view image) in the sub-display area alongside the first predetermined area (from the current wide-view image) in the main display area. This equipotential approach ensures both images are represented in the same standardized format, allowing users to easily compare changes over time while maintaining the accuracy of each image's captured area.
3Area of stationary object
If curved wide-view images are displayed to capture entire locations, then comprehensive coverage is achieved, but user understanding and coordination become difficult
Solution Approach 1:
The patent segments the curved wide-view image into a main display area showing the first predetermined area and a sub-display area showing the second predetermined area. This segmentation preserves the comprehensive imaging range of the wide-view image while preventing spatial confusion by providing a corrected reference view that maintains proper spatial relationships and orientation for user understanding.

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.
