Color Adjustment Device Isolating White Color Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display devices face challenges in achieving desirable image quality due to color shifts during signal transmission and processing, particularly in adjusting the white color, which affects other color parameters, making precise adjustments difficult.
Innovation Solution
A color adjustment device and method that generates a weight and color shift value based on the image's first color value, using a weight generating unit, color shift value generating unit, and adjustment unit to produce a second color value, primarily focusing on grey level transformation to isolate white color adjustments with minimal impact on other colors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional color adjustment methods are used to adjust one color parameter, then that specific color can be modified, but other color parameters and true colors are affected by the adjustment
Solution Approach 1:
The patent segments the color adjustment process by introducing a weight generating unit that calculates different weights for different color components (R, G, B) based on their saturation levels. This allows independent adjustment of each color component's contribution to the overall color correction, preventing adjustments to one parameter from adversely affecting others.
Solution Approach 2:
The patent applies local quality by calculating saturation values for each color component and using these saturation values to determine specific weights for each component. This ensures that color adjustment is applied selectively and appropriately to each color channel based on its individual properties, rather than applying a uniform adjustment to all colors.
2Measurement precision
If white color adjustment is performed using traditional methods, then white color can be corrected, but the adjustment impacts other color parameters and true colors
Solution Approach 1:
The patent segments the white color correction process by calculating individual saturation values for R, G, and B components and using these to determine specific weights for each component. This segmented approach allows precise white color correction while minimizing interference with other color parameters through controlled, component-specific adjustment.
Solution Approach 2:
The patent changes the adjustment parameters by introducing saturation-based weights as new control parameters. Instead of directly adjusting color values, the system adjusts the weights that control how much each color component contributes to the correction, providing more precise control over white color correction while reducing harmful effects on other parameters.

AI summary
Device and method for color adjustment for adjusting white color of an image including a weight generating unit, a color shift value generating unit, and an adjustment unit. The weight generating unit receives a first color value of the image and generates a weight according to the first color value. The color shift value generating unit receives the first color value and the weight and generates a color shift value according to the first color value and the weight. The adjustment unit receives the first color value and the color shift value and generates a second color value according to the first color value and the color shift value.
