Image Viewpoint Matching for Subject Visibility

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing techniques fail to display a second image related to a first image on a display such that a subject displayed by the first image is easily visible, requiring time-consuming scrolling operations and increasing processing loads.

Innovation Solution

The method involves displaying a first image obtained by photographing a predetermined space on a specific date and time, and upon detecting an instruction to select a different date and time, displaying a second image while changing the default viewpoint to match the viewpoint of the first image, thereby ensuring the subject from the first image is visible in the second image without needing to scroll.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the second image is displayed with the default viewpoint, then the display operation is simple, but the subject from the first image cannot be seen in the second image

Engineering Contradiction:

Improvedisplay operationVSAvoidsubject visibility

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The system performs preliminary action by automatically adjusting the viewpoint of the second image to match the viewpoint of the first image before display. This pre-adjustment ensures that the subject is visible in the second image without requiring manual scrolling operations from the user, thus resolving the contradiction between simple display operation and subject visibility.

Inventive Principle:

Principle #10Preliminary action

2Loss of information

If the viewpoint of the second image is adjusted to match the first image, then the subject is visible, but the processing load increases

Engineering Contradiction:

Improvesubject visibilityVSAvoidprocessing load

Core Design Contradiction:

Loss of informationVSPower

Solution Approach 1:

The system uses copying by directly adopting the viewpoint parameters from the first image and applying them to the second image. Instead of performing complex calculations to determine the appropriate viewpoint, the system copies the viewpoint settings, which significantly reduces the processing load while ensuring the subject remains visible in both images.

Inventive Principle:

Principle #26Copying

3Measurement precision

If manual scrolling is required to see the subject in the second image, then the viewpoint can be adjusted precisely, but the operation becomes time-consuming

Engineering Contradiction:

Improveviewpoint adjustment precisionVSAvoidoperation time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system implements self-service by automatically performing the viewpoint adjustment task that would otherwise require manual user intervention. The system itself adjusts the second image's viewpoint to match the first image, eliminating the need for users to perform time-consuming manual scrolling operations while maintaining precise viewpoint alignment.

Inventive Principle:

Principle #25Self-service

AI summary

An information processing device displays, on a display of an information terminal, a first image obtained by photographing a predetermined space on first date and time; and when detecting an instruction to select second date and time different from the first date and time, displays, on the display, a second image obtained by photographing the predetermined space on the second date and time, in which the second image is displayed on the display while having a default viewpoint being changed so as to match a viewpoint of the first image.
