Vector Image Color Grouping Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current graphics design applications face difficulties in intuitively editing vector images due to the inability to distinguish between colors with slightly different RGB values, limiting the degree of freedom in color changes and requiring complex processing for color clustering.
Innovation Solution
A user interface that extracts colors from vector images, groups similar colors using representative colors, and allows users to select a color from a palette to replace colors within a group, simplifying the editing process by displaying representative colors and allowing intuitive color changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If colors with slightly different RGB values are handled as different colors, then color precision is improved, but ease of operation deteriorates because users cannot intuitively distinguish and select colors
Solution Approach 1:
The patent merges colors with slightly different RGB values into the same color group by introducing a color group management mechanism. This combines visually similar colors into unified groups, allowing users to select representative colors that apply to multiple similar colors simultaneously, thereby improving ease of operation while maintaining adequate color distinction.
Solution Approach 2:
The patent introduces a color group manager as an intermediary between the raw color data and the user interface. This intermediary processes and organizes colors into groups, presenting simplified color selection options to users while maintaining the underlying precision of individual color values.
2Adaptability or versatility
If all colors are listed individually for editing, then degree of freedom in editing is improved, but device complexity increases due to large number of color options
Solution Approach 1:
The patent combines multiple similar colors into color groups, reducing the number of individual color options presented to users. This merging approach maintains editing flexibility within groups while significantly reducing interface complexity by presenting consolidated color groups instead of individual colors.
Solution Approach 2:
The patent segments colors into meaningful groups based on visual similarity, creating a hierarchical structure where color groups contain individual colors. This segmentation allows users to navigate and select colors more efficiently by working with groups rather than individual colors, reducing interface complexity while preserving editing freedom.
3Measurement precision
If complex clustering methods are used to group colors, then color grouping accuracy is improved, but processing time increases
Solution Approach 1:
The patent changes the approach from complex clustering algorithms to a simpler parameter-based grouping method. Instead of using computationally intensive clustering, the system uses RGB value thresholds and visual similarity metrics to group colors, achieving adequate accuracy with significantly reduced processing time.
Solution Approach 2:
The patent employs simple, lightweight color grouping criteria rather than complex, computationally expensive clustering algorithms. This uses basic RGB value comparisons and threshold-based grouping, which are faster and more efficient for the task at hand, sacrificing some theoretical optimality for practical performance.

AI summary
An information processing apparatus extracts colors used for an image, links each color to one of color groups including a first color group and a second color group, displays, in a first region of a UI, a representative color associated with a group, of the color groups, to which extracted color is linked, displays a color palette including one color in a second region of the UI, and replaces a color included in the image and belonging to the color group associated with the selected representative color with a color selected from the color palette. If the color groups include groups to which at least one extracted color is linked, representative colors respectively associated with the groups to which at least one of the extracted colors is linked are displayed in the first region.
