Primary Color Adjustment Using Hue-Weighted Interference Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for adjusting primary color components in images fail to consider color interference between primary colors, leading to discontinuation of color representation across different display devices with varying color representation characteristics.
Innovation Solution
An apparatus and method that determine a weight based on hue differences between object hue components and adjustment primary colors, adjusting hue and saturation components to account for color interference, using a weight determiner and component adjuster to refine the color representation, particularly in regions where color interference occurs between primary colors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional techniques adjust hue and saturation components only for a primary color without considering color interference, then the adjustment process is simple, but color representation discontinuation occurs
Solution Approach 1:
The patent segments the color adjustment process by identifying specific adjustment ranges in the color space where color interference occurs between primary colors. Instead of uniformly adjusting all colors, the system divides the color space into regions requiring different adjustment strategies, thereby maintaining color representation continuity without overly complicating the overall adjustment process.
Solution Approach 2:
The patent applies local quality by determining adjustment ranges specifically in regions of the color space where color interference occurs between primary colors. Different hue and saturation adjustment amounts are applied locally to these specific regions rather than uniformly across the entire color space, ensuring color continuity where it matters most while keeping the adjustment process manageable.
2Reliability
If adjustment ranges cover regions where color interference occurs between primary colors, then color representation consistency is improved, but the calculation complexity increases
Solution Approach 1:
The patent performs preliminary action by pre-determining adjustment ranges in the color space where color interference between primary colors occurs. By identifying and marking these regions in advance, the system prepares the necessary adjustment parameters before actual color adjustment is needed, reducing real-time calculation complexity while ensuring color representation consistency in critical regions.
Solution Approach 2:
The patent introduces an intermediary mechanism through the weight determination process. A weight corresponding to hue difference is calculated as an intermediary parameter between the object hue component and the adjustment primary color. This weight mediates the adjustment process, allowing the system to handle complex color interference relationships through a structured intermediate calculation step.
3Measurement precision
If weight is determined based on hue difference between object hue components and adjustment primary color, then color interference is accounted for, but the adjustment algorithm becomes more complex
Solution Approach 1:
The patent applies parameter changes by determining a weight parameter based on the hue difference between object hue components and adjustment primary colors. This weight parameter dynamically changes according to the hue difference, allowing the adjustment algorithm to account for color interference with a single additional parameter calculation rather than complex multi-dimensional adjustments.

AI summary
An apparatus for and a method of adjusting a primary color component of an image and a computer-readable recording medium for storing a computer program for controlling the apparatus. The apparatus includes: a weight determiner which determines a weight corresponding to a hue difference between a hue of each of plural object hue components and a hue of adjustment primary color; and a component adjuster which adjusts at least one of object hue and saturation components using at least one of saturation and hue adjustment amounts of the adjustment primary color and the weight. The object hue and saturation components are components of hue and saturation components of an input image belonging to an adjustment range, the adjustment range belongs to a region of a color space in which color interference between the adjustment primary color and a neighboring primary color occurs, the adjustment primary color corresponds to a primary color to be adjusted, and the neighboring primary color corresponds to a primary color neighboring the adjustment primary color.
