Color Adjustment Apparatus Segmentation for Vividness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video-display systems struggle to present vivid colors in natural images due to complex backgrounds, as manual adjustments in RGB, YCbCr, or HIS formats often distort color coordinates, failing to meet user visual demands.
Innovation Solution
A color adjustment apparatus with a calculation unit that divides input color signals into groups and generates calculation signals to adjust contrast and complementary colors, using predetermined color values to enhance vividness without affecting other color presentations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If manual adjustment methods are used in RGB, YCbCr, or HIS formats to enhance color vividness, then color presentation can be improved, but color coordinates become distorted and other colors are affected
Solution Approach 1:
The patent segments the color adjustment process by dividing color signals into different color groups (first color group and second color group with contrast or complementary relationships). By processing each color group separately with targeted adjustment parameters, the system enhances vividness without causing cross-color distortion, thereby resolving the contradiction between color vividness and color coordinate accuracy.
2Ease of operation
If color adjustment is performed on natural images with complex backgrounds, then visual perception can be enhanced, but color distortion occurs due to interdependence of color coordinates
Solution Approach 1:
The patent applies local quality by using judgment units to identify specific regions or color ranges within the image that require adjustment. Instead of uniformly adjusting all colors, the system selectively applies enhancement to specific color groups based on their contrast or complementary relationships, thereby improving visual perception while maintaining accuracy in other color regions.
3Measurement precision
If single color adjustment is performed to meet user visual demands, then one color can be optimized, but other colors are affected and overall color balance is compromised
Solution Approach 1:
The patent implements feedback mechanisms through judgment units that continuously monitor color signal characteristics and adjustment effects. Based on this feedback, the system dynamically adjusts enhancement parameters for different color groups, ensuring that optimization of one color does not compromise the stability of other colors. The feedback loop maintains overall color balance while achieving precise optimization of target colors.
