Solution Overview

Problem

Color blind individuals face difficulties in perceiving certain colors, leading to inefficient battery consumption in display devices, as existing solutions often result in distorted images or neglect power consumption considerations.

Innovation Solution

A system and method that detects a user's color deficiency spectrum and dynamically modifies images using lower RGB values to reduce power consumption, allowing color blind users to distinguish colors while minimizing battery drain, employing a color blindness detector, analyzer, and image modifier to replace non-perceived colors with darker shades.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If bright colors are displayed to provide vivid color-coded information, then visual information quality is improved, but battery consumption increases

Engineering Contradiction:
Improvedisplay brightnessVSAvoidbattery consumption
Core Design Contradiction:
Illumination intensityVSUse of energy by moving object

Solution Approach 1:

The patent applies local quality by selectively modifying only the color components that are invisible to color-blind users while preserving other color information. The system identifies specific color ranges (e.g., red-green or blue-yellow spectra) that the user cannot perceive and replaces only those with darker shades, rather than uniformly darkening the entire display. This localized approach maintains visual information quality for perceivable colors while reducing power consumption for non-perceivable color ranges.

Inventive Principle:
Principle #3Local quality

2Ease of operation

If color information is remapped to black and white to assist color blind users, then color perception is improved, but image quality deteriorates

Engineering Contradiction:
Improvecolor perceptionVSAvoidimage quality
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent preserves image quality by applying color modification locally only to the specific color spectrum that the color-blind user cannot perceive. Instead of converting the entire image to black and white, the system selectively adjusts only the problematic color ranges (e.g., replacing red-green distinctions with luminance-based variations) while leaving other color information intact. This selective local modification maintains overall image richness and detail while providing necessary color differentiation assistance.

Inventive Principle:
Principle #3Local quality

3Loss of information

If bright colors are displayed for color blind users, then color information is provided, but power consumption increases without benefit

Engineering Contradiction:
Improvecolor information deliveryVSAvoidpower consumption
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

The patent converts the harmful waste of energy into a benefit by identifying colors that color-blind users cannot perceive and replacing them with darker shades. The 'harm' of displaying colors that provide no informational value to color-blind users is transformed into energy savings. The system detects which color spectrum the user lacks (e.g., red-green deficiency) and systematically replaces those specific color ranges with darker alternatives, thereby converting wasted energy expenditure into useful battery conservation while maintaining complete color information delivery for perceivable ranges.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

A system and method for detecting spectrum of colors that is indistinguishable to a color blind individual and modifying the colors to fade in or out to the shade of same color, is provided. While the partial color blind user is enabled to view and better distinguish colors that were problematic earlier, the present invention achieves a significant reduction in power consumption of the display device with this modified color set.
