Display Color Adjustment for Vision Deficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users with color vision deficiencies face difficulties in recognizing images displayed on electronic devices due to their inability to differentiate between certain colors, which can impact their ability to perceive and appreciate color-dependent information.
Innovation Solution
A display device and method that adjust the color of images in real-time based on user input, using a color adjustment interface to modify RGB values and display both color vision deficiency test images and natural images, allowing users to assess and correct color perception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If color adjustment is applied to help users with color vision deficiencies, then color discrimination ability is improved, but the natural appearance of images is degraded
Solution Approach 1:
The system dynamically adjusts color parameters based on real-time user input and selection. Users can interactively modify color values for different color vision deficiency types (deuteranopia, protanopia, tritanopia, achromatopsia) and the display adapts accordingly, allowing optimization between color discrimination and natural appearance without fixed predetermined settings
Solution Approach 2:
The invention changes color parameters (RGB values) of displayed images based on detected color vision deficiency type and user preferences. The system modifies color values to enhance distinguishability for users with color vision deficiencies while providing controls to maintain natural appearance when desired, thus resolving the contradiction between improved discrimination and natural appearance
2Adaptability or versatility
If real-time color adjustment is implemented, then user customization is improved, but device complexity increases
Solution Approach 1:
The system provides universal color adjustment functionality that handles multiple color vision deficiency types (deuteranopia, protanopia, tritanopia, achromatopsia) through a single integrated interface. The same device components (display, processor, input interface) serve multiple functions: displaying content, detecting user input, calculating adjusted color values, and rendering the corrected output, thus achieving high adaptability without proportionally increasing complexity
Solution Approach 2:
The system allows users to self-configure their color adjustment preferences by selecting their specific color vision deficiency type and adjusting color parameters interactively. The device automatically applies the selected adjustments without requiring complex external configuration or manual calibration by technicians, enabling high user customization through simple self-service operations

AI summary
A method of driving a display device includes displaying both a natural image and a color vision test image on the display unit. The color vision test image is an image used to determine whether a person has a color vision impairment. A color adjustment user interface for adjusting color of the display unit is displayed on the display unit. A color adjustment instruction that instructs to adjust color of the display unit is received via an input unit. Supply image data supplied to the display unit is adjusted based on the color adjustment instruction by using a controller.
