Solution Overview

Problem

Existing technologies face challenges in accurately determining information related to devices displayed in images, particularly due to the influence of external light, leading to incorrect device identification and misinterpretation of information.

Innovation Solution

An information display device that includes an actual image obtaining unit, a device information specifying unit, and an information display unit, which determines the influence of external light on the image and uses a trained model to accurately identify the device, generating an unevenness emphasized image to enhance recognition and providing notifications for improved accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If image capture is performed in environments with external light, then the device can be identified, but the accuracy of device information determination deteriorates due to light reflection and halation

Engineering Contradiction:

Improveimage capture capabilityVSAvoiddevice information determination accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent converts the harmful effect of external light (reflection and halation) into a beneficial diagnostic feature. By detecting specific light patterns characteristic of reflection and halation, the system identifies these artifacts and applies appropriate corrections or flags, thereby transforming what was previously a source of error into a detectable and correctable condition that improves overall measurement precision

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent introduces an intermediary analysis layer between image capture and device identification. This intermediary component analyzes the captured image for light artifacts, determines their presence and severity, and applies corrective measures before final device information is extracted, thereby mediating between the raw image data and the final identification result to maintain accuracy

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of information

If the system attempts to identify device information from images with light influence, then information can be obtained, but incorrect device determination occurs

Engineering Contradiction:

Improveinformation retrievalVSAvoiddevice determination accuracy

Core Design Contradiction:

Loss of informationVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the system analyzes the captured image for light artifacts, uses this analysis feedback to determine whether the image is suitable for accurate device identification, and either requests a new image or applies corrections based on the feedback, thereby improving reliability before final device determination

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent performs preliminary analysis of the captured image to detect light artifacts before proceeding with device identification. This preliminary action of detecting and flagging light influence ensures that device determination is only performed when image quality is sufficient, preventing incorrect identification from occurring in the first place

Inventive Principle:

Principle #10Preliminary action

3Strength

If the device has a transparent cover, then the display is protected, but light reflection on the cover surface inhibits information identification

Engineering Contradiction:

Improvedisplay protectionVSAvoidinformation identification accuracy

Core Design Contradiction:

StrengthVSMeasurement precision

Solution Approach 1:

The patent converts the harmful light reflection on the transparent cover into a detectable pattern. By specifically identifying reflection patterns that originate from the cover surface versus the display content, the system can distinguish between actual device information and artifact-induced false patterns, thereby maintaining identification accuracy despite the protective cover's reflective properties

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

A user terminal includes an actual image obtaining unit that obtains an actual image in which an electronic timepiece is displayed, a model determining unit that specifying information about the electronic timepiece based on the actual image, an information display unit that displays information about the electronic timepiece. The model determining unit determines whether the actual image is influenced by external light based on the actual image, where the influence of the external light occurs when the actual image is obtained and inhibits identification of the information about the electronic timepiece.
