Solution Overview

Problem

Users of glasses-type display devices experience a sense of incongruity when trying to visually recognize display images as virtual images overlaid on real spaces due to inconsistent image processing that does not account for individual visual characteristics.

Innovation Solution

A processor in the glasses-type display device performs image processing based on the user's visual characteristics, such as visual acuity, to simulate and adjust the image quality of display images, ensuring they align with the user's perception of real-space objects, thereby reducing blurriness and enhancing the immersive experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If image processing is performed on the display image regardless of the user, then the processing can be simplified and performed uniformly, but the user experiences a sense of incongruity when visually recognizing the display image as a virtual image together with the real space

Engineering Contradiction:
Improveimage processing simplicityVSAvoidvisual recognition coherence
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent applies parameter changes by adjusting image processing parameters (such as blur degree, contrast, brightness) based on individual user visual characteristics. The processing unit changes these parameters dynamically according to each user's visual acuity and other visual attributes, transforming the uniform processing approach into a personalized one that maintains visual coherence without requiring complete redesign of the processing system

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements dynamics by making the image processing adaptive and variable rather than static. The processing unit dynamically adjusts processing intensity and type based on detected user visual characteristics, allowing the system to respond to different users and even different viewing conditions for the same user, thereby achieving visual coherence through flexible adaptation

Inventive Principle:
Principle #15Dynamics

2Reliability

If image processing is performed to simulate visual characteristics, then the visual coherence is improved, but the processing complexity and computational load increase

Engineering Contradiction:
Improvevisual coherenceVSAvoidprocessing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-detecting and storing user visual characteristics before actual image processing occurs. The processing unit acquires visual characteristic information in advance and uses this pre-acquired data to guide subsequent processing operations, avoiding the need for complex real-time analysis during image rendering and reducing overall processing complexity

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent applies local quality by applying different processing intensities and types to different regions or aspects of the display image based on user visual characteristics. Rather than uniformly processing the entire image with high complexity, the system selectively applies processing where most needed, optimizing the balance between visual coherence and processing complexity

Inventive Principle:
Principle #3Local quality

AI summary

A processor is included in a glasses-type display device that is capable of allowing a user to visually recognize a display image displayed on a display unit as a virtual image together with a real space, and the processor performs image processing based on a visual characteristic of the user on the display image, and displays the display image after the image processing on the display unit.
