Image Processing Device Color Weakness Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with color weakness face difficulties in recognizing certain colors, leading to ineffective communication of intended color usage in documents with multiple colors, as existing technologies fail to accurately convey color information.
Innovation Solution
An image-processing device that extracts areas within a specific color range and applies effects to these areas, allowing users to select and apply alternative effects, thereby enhancing color recognition and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple colors are used in a document to convey different information, then the information communication capability is improved, but individuals with color weakness cannot recognize certain colors, leading to loss of information
Solution Approach 1:
The patent introduces an effect application as an intermediary mechanism between the original color information and the final displayed image. When the system detects that an area has a color difficult to recognize for color-weak individuals, it applies additional visual effects (such as patterns, borders, or texture modifications) to that area. This intermediary effect serves as a backup communication channel that conveys the same information without relying solely on color perception, thereby resolving the contradiction between using multiple colors for information encoding and ensuring accessibility for color-weak individuals.
2Ease of operation
If effects are applied to areas with difficult-to-recognize colors, then color recognition is improved, but the device complexity increases due to multiple processing units required
Solution Approach 1:
The patent designs the image processing device with multi-functional processing units that can perform both color space conversion and effect application functions. The color space conversion unit and effect application unit are integrated such that they can work independently or in combination depending on the situation. This universal design allows the system to maintain enhanced color recognition capabilities while avoiding the need for separate dedicated hardware for each function, thereby reducing overall device complexity while preserving the beneficial effects.
3Loss of information
If effect data is obtained and applied to specific color ranges, then the conveyance of intended color usage is improved, but the processing time and complexity increase
Solution Approach 1:
The patent implements preliminary action by pre-defining color ranges and their associated effects in a database or configuration files before actual image processing occurs. When processing an image, the system quickly references these pre-established mappings rather than calculating appropriate effects from scratch. This approach significantly reduces processing time while still maintaining the ability to accurately convey the intended color usage information to color-weak individuals, as the effect application logic has already been prepared in advance.

AI summary
An image-processing device includes: an obtaining unit that obtains image data; an area extraction unit that extracts an area having a color falling within a predetermined range of a color within a color space, in an image represented by the obtained image data; an effect extraction unit that extracts an effect applied to the image represented by the obtained image data; an effect data obtaining unit that if a type of the extracted effect is included in predetermined plural types of effect, obtains effect data representing a type of effect selected from among the predetermined plural types of effect, excluding a type of the extracted effect; and a generating unit that generates image data representing an image in which an effect of the type represented by the obtained effect data is applied to the area extracted by the area extraction unit.
