Color Recognition Aid for Color-Blind Users
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Color-blind individuals face difficulties in grasping colors, especially when only color names are provided, and presenting color values does not help them intuitively understand the colors.
Innovation Solution
An image processing system that obtains color information from a target image, compares it to stored color information, and provides similarity notifications to users, including reference images and color group information, to aid in color recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If color names are presented to color-blind persons, then color identification is simplified, but color distinction accuracy deteriorates because color names cannot capture hue variants
Solution Approach 1:
The patent segments color information into multiple dimensions: color name (for simplicity) and color value (for precision). By dividing the color representation into these separate components, the system allows color-blind users to access both simplified names and detailed numerical data that capture hue variants, resolving the contradiction between simplicity and accuracy.
Solution Approach 2:
The patent introduces an intermediary layer by presenting color values (RGB, HSV, etc.) as a bridge between color names and actual color perception. This intermediary provides quantitative data that color-blind users can interpret to distinguish between color variants while maintaining the simplicity of color names for general identification.
2Measurement precision
If color values (RGB) are presented to color-blind persons, then color distinction accuracy is improved, but ease of understanding deteriorates because intuitive color perception is lost
Solution Approach 1:
The patent merges multiple types of color information (color names, color values, and reference images) into a comprehensive presentation system. This combination allows color-blind users to benefit from both the precision of numerical values and the intuitive understanding provided by visual references and descriptive names, eliminating the trade-off between accuracy and ease of understanding.
Solution Approach 2:
The patent uses reference images as copies or representations of actual colors. These visual copies provide intuitive color perception for color-blind users while the system simultaneously provides the corresponding numerical color values for precise distinction. The reference images serve as a bridge that maintains both accuracy and intuitiveness.
3Device complexity
If only color names are provided, then information simplicity is maintained, but color information completeness deteriorates due to loss of hue variant details
Solution Approach 1:
The patent adds another dimension to color information presentation by incorporating color values (RGB, HSV, etc.) alongside color names. This dimensional expansion allows the system to maintain simplicity through names while capturing complete color information including hue variants through the additional numerical dimension.
Solution Approach 2:
The patent prepares multiple types of color information (names, values, and reference images) in advance and presents them together. This preliminary preparation ensures that when users need color information, both simple names and complete details with hue variants are immediately available, preventing information loss while maintaining simplicity.
4Loss of information
If color information is presented in multiple formats, then color information completeness is improved, but system complexity increases
Solution Approach 1:
The patent creates a universal color information presentation system that handles multiple formats (names, values, images) through a single integrated structure. This multi-functional approach allows the system to provide complete color information without increasing complexity, as all formats are managed within one unified framework rather than separate systems.
Data Source
AI summary
A color information obtaining unit obtains color information of an attention point or an attention area within a target image. A similarity information obtaining unit obtains similarity information related to a level of similarity between color information of an image that is stored in a storage in advance and the color information obtained by the color information obtaining unit. A notification unit causes an output unit to output a notification based on the similarity information.
