Solution Overview

Problem

Users visiting the shooting location of an image often fail to replicate the experience depicted in the image due to differences in time of day, as the actual scene appears differently from the captured image, even if they visit the location at a different time.

Innovation Solution

A route search system that associates image data with location and time information, allowing users to select a location and time for visiting, thereby enabling the system to search and display routes that match the original shooting conditions, ensuring the user experiences the scene as intended.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If users visit the shooting location of an image, then they can see the actual scene, but the scene appears differently from the image due to time differences

Engineering Contradiction:
Improveaccuracy of experience replicationVSAvoidtime difference between image capture and visit
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary actions by storing the time information when the image was captured, and then uses this stored information to determine the optimal visiting time. This allows users to plan their visit in advance at the same time of day as the original photograph, ensuring the scene appears as it did in the image.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system provides feedback to users by displaying the time information associated with the image and recommending specific visiting times. This feedback loop enables users to adjust their visit plans based on the original shooting conditions, thereby replicating the visual experience accurately.

Inventive Principle:
Principle #23Feedback

2Measurement precision

If the system stores detailed time information for each image, then it can recommend accurate visiting times, but the system complexity increases

Engineering Contradiction:
Improveprecision of visiting time recommendationVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system extracts only the essential time information (time of day) from the complete timestamp data, storing and utilizing only the portion necessary for determining optimal visiting times. This extraction approach maintains recommendation precision while avoiding the complexity of managing and processing entire timestamp data for each image.

Inventive Principle:
Principle #2Taking out (Extraction)

3Measurement precision

If the system searches for routes considering both location and time, then it can provide accurate visiting routes, but the searching complexity increases

Engineering Contradiction:
Improveaccuracy of route recommendationVSAvoidsearching complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The route search function is segmented into two independent components: location-based routing and time-based optimization. The system first determines the optimal visiting time based on stored time information, then searches for routes considering this specific time constraint. This segmentation reduces searching complexity by breaking down the combined problem into manageable separate tasks.

Inventive Principle:
Principle #1Segmentation

AI summary

A user is induced to have the same experience as displayed in an image. Means that obtains content stored in a route search system obtains content stored in storing means for storing a plurality of items of image data, location information, and time information in association with one another. Display controlling means displays some of the items of image data on display means. Receiving means receives a selection of a location to visit from the displayed items of image data. Searching means determines a visiting location based on location information of the image data of the selected location, determines a visiting time based on time information of the image data, and searches a route for visiting the visiting location on the visiting time.
