Six-Primary Color System for Gamut Expansion and Metameric Error Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current RGB color systems are limited in their color gamut and suffer from viewer metameric errors due to the use of narrow emissive spectra, leading to increased power consumption and operational costs, and existing multi-primary display systems do not effectively manage additional color primaries outside of the display.
Innovation Solution
A six-primary color system is implemented, incorporating cyan, yellow, and magenta primaries, with a system for acquiring, transporting, and displaying image data using a set of image data converters, digital interfaces, and modified Session Description Protocol parameters to ensure consistent color perception across viewers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a three-primary RGB color system is used, then the system complexity is low, but the color gamut is limited and viewer metameric errors occur
Solution Approach 1:
The color system is segmented into three distinct primary color channels (cyan, yellow, magenta) that can be independently controlled and processed. Each primary color is handled as a separate component through the imaging pipeline, allowing for precise manipulation of each color channel while maintaining overall system manageability
Solution Approach 2:
The six-primary color system is designed to be universally compatible with existing imaging infrastructure. The system can process both traditional three-primary image data and six-primary image data, and can adapt to different display devices regardless of their specific primary color implementation, making it a multi-functional solution that addresses both color gamut expansion and system compatibility
2Use of energy by moving object
If narrow emissive spectra are used in RGB systems, then the power consumption is high, but the color gamut coverage is insufficient
Solution Approach 1:
The system changes the spectral parameters of the light emission by using wide bandwidth spectral outputs instead of narrow spectra. This parameter change allows the six-primary color system to achieve broader color gamut coverage while reducing the power consumption required to produce the same perceived brightness, as the wider spectral distribution more efficiently stimulates the human eye's color receptors
3Adaptability or versatility
If additional color primaries are added outside the display, then the color gamut is expanded, but the management of additional primaries becomes complex
Solution Approach 1:
The image data converter serves as an intermediary component that mediates between the additional color primaries and the display system. It performs the necessary color space transformations and data formatting, converting six-primary image data into a format that can be processed by standard display interfaces while preserving the expanded color gamut information
Solution Approach 2:
The system adds color primaries in another dimension by incorporating cyan, yellow, and magenta channels alongside the traditional red, green, and blue channels. This dimensional expansion of the color space is managed through extended Session Description Protocol parameters that provide a structured framework for handling the additional color dimensions without overwhelming the system's operational complexity
