Color Correction System for Wide Gamut Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wide color gamut image output devices display unnatural colors for specific colors like skin and green grass due to color attribute differences, and fail to demonstrate vivid colors for high saturation non-memory colors, as they are not optimized for conventional sRGB or EBU specifications.
Innovation Solution
A color correction system comprising an identification unit, correction unit, and adjustment module that classifies and corrects specific and non-specific color data, using analysis of the output device's color characteristics to minimize color differences and enhance visual effects by extending or mapping color data within or outside the device's gamut.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wide color gamut image output devices display colors according to conventional sRGB or EBU specifications, then the device capabilities for displaying vivid colors are not fully demonstrated, but the displayed colors appear strange or unnatural for memory colors like skin, green grass or blue sky
Solution Approach 1:
The patent segments color data into two categories: specific color data (memory colors like skin, green grass, blue sky) and non-specific color data (high saturation non-memory colors). Different processing methods are applied to each category to simultaneously achieve color accuracy for memory colors and vividness for non-memory colors, resolving the contradiction between color gamut capability and color accuracy.
Solution Approach 2:
The patent applies different quality adjustments to different color regions. For specific memory colors, color correction is applied to minimize color differences and achieve natural appearance. For non-specific high saturation colors, color extension and enhancement are applied to demonstrate the device's vivid color capabilities. This local differentiation resolves the contradiction by optimizing each color type according to its specific requirements.
2Manufacturing precision
If color data is corrected to minimize color differences for specific colors, then color accuracy for memory colors is improved, but the vivid color display capability for non-specific colors may be reduced
Solution Approach 1:
The patent divides color data processing into two distinct paths: one for specific color data that emphasizes accuracy and natural appearance, and another for non-specific color data that emphasizes vividness and saturation. This segmentation allows both color accuracy and vivid color display capability to be optimized simultaneously without compromise.
Solution Approach 2:
The patent changes processing parameters based on color type: for specific colors, correction parameters are applied to minimize color differences; for non-specific colors, extension and enhancement parameters are applied to maximize vividness. This dynamic parameter adjustment resolves the contradiction by adapting the processing approach to the specific color category.

AI summary
A color correction system and a method thereof are disclosed. A correction system according to the present invention includes an identification unit, a correction unit, and an adjustment module. The way of correction includes following steps: firstly the identification unit receives an image color data and identifies whether the image color data is a specific or a non-specific color data. Then the correction unit corrects the specific color data for display while the non-specific color data is adjusted by the adjustment module according to the color characteristics of the image output device. Therefore, the image data to be displayed is corrected and display quality of the image output device is improved.
