Solution Overview

Problem

Existing image analysis methods struggle to effectively distinguish deformation objects from their background when their colors are similar, making it difficult for users to visually recognize and differentiate various types of deformations in structures.

Innovation Solution

An image processing apparatus and method that superimposes deformation objects on images, adjusting their colors based on the background colors to enhance visibility, using a combination of hue, saturation, and brightness changes to differentiate between deformation types.

1Reliability

If deformation objects are displayed with fixed colors on the image, then the display process is simple, but the deformation objects cannot be distinguished from their background when colors are similar

Engineering Contradiction:

Improvedistinguishability of deformation objectsVSAvoidcolor adjustment control complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies color changes by automatically adjusting the color of deformation objects based on the background color at their position. The display control unit changes the hue, saturation, or brightness of the deformation object's color to ensure it differs from the background color, making the deformation object distinguishable while maintaining a relatively simple display process.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The patent implements parameter changes by modifying color parameters (hue, saturation, brightness) of the deformation objects. The system determines the background color at the deformation object's position and adjusts the object's color parameters to create sufficient contrast, resolving the contradiction between simple display and reliable distinguishability.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If the color of deformation objects is changed to match any background, then visibility is improved, but the ability to differentiate between different deformation types is reduced

Engineering Contradiction:

Improvevisibility of deformation objectsVSAvoiddeformation type information

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent applies local quality by making different parts of the display have different color characteristics. Each deformation object's color is locally adjusted based on its specific background while maintaining consistent color coding for different deformation types. This allows the system to differentiate deformation types through color while ensuring each object is visible against its specific background.
