Solution Overview

Problem

Mobile devices with cameras face challenges in analyzing changes in objects over time due to variations in capture distance and angle, leading to potential misinterpretation of actual changes.

Innovation Solution

A mobile device system that displays a reference image alongside preview images, uses a distance detection mechanism to indicate if the current distance matches the reference image's capture distance, and acquires metadata to ensure consistent camera settings, allowing users to capture images at the same distance and angle as the reference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple images of the same object are captured over time without controlling capture conditions, then image acquisition is simple and quick, but the accuracy of analyzing changes in the objects deteriorates due to variations in distance and angle

Engineering Contradiction:
Improveaccuracy of analyzing changesVSAvoidcomplexity of capture condition control
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system captures a reference image first, storing its metadata including distance and angle information. This preliminary action establishes a baseline against which subsequent images are compared, allowing the system to guide future captures to match the reference conditions without requiring complex real-time control mechanisms.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system provides feedback to the user by comparing the capture conditions of subsequent images with the reference image metadata. It indicates whether the distance and angle match the reference, enabling the user to adjust positioning to achieve consistent imaging conditions for accurate change analysis.

Inventive Principle:
Principle #23Feedback

2Measurement precision

If the system provides detailed guidance and control for maintaining consistent capture conditions, then the accuracy of change analysis improves, but the ease of operation deteriorates

Engineering Contradiction:
Improveconsistency of imaging conditionsVSAvoidease of capturing images
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system performs automatic comparison of capture conditions between the reference image and subsequent images. It calculates whether distance and angle parameters match within acceptable tolerances and provides guidance without requiring manual measurement or complex user intervention, making the process self-guiding and easy to operate.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system monitors and compares key parameters (distance, angle) between reference and subsequent captures. By focusing on these critical parameters and providing feedback when they deviate from the reference values, the system maintains imaging consistency through simple parameter matching rather than complex control procedures.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If the system displays both reference image and preview image simultaneously, then the user can easily compare and maintain consistent positioning, but the device complexity increases

Engineering Contradiction:
Improveease of positioningVSAvoidcomplexity of display system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system merges the display of the reference image and the live preview image from the camera into a single unified interface. This allows users to see both images simultaneously on the same display, easily comparing their alignment and positioning without requiring multiple separate displays or complex switching mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The reference image is displayed as a static copy or overlay alongside the live preview. This copying approach allows direct visual comparison of the reference positioning with the current camera view, helping users align their capture conditions without adding complex real-time processing or multiple display systems.

Inventive Principle:
Principle #26Copying

AI summary

A reference image of one or more objects is displayed on the display of a mobile device in a manner that allows a user of the mobile device to simultaneously view the reference image and a preview image of the one or more objects currently in a field of view of a camera of the mobile device. An indication is provided to the user of the mobile device whether the camera of the mobile device is currently located within a specified amount of a distance at which the reference image was acquired. In response to a user request, the camera acquires a second image of the one or more objects and optionally a distance between the camera and the one or more objects at the time the second image was acquired is recorded. An image management application provides various functionalities for accessing and managing image sequences.
