Color Conversion Lookup Table Generation for User Preference Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing color printing technologies often mismatch ink combinations determined by designers with user preferences, particularly for specific colors like red, green, or blue, and face challenges in downsizing, cost reduction, resource saving, and usability improvement.
Innovation Solution
A method and apparatus for generating a color conversion lookup table that acquires parameter values representing a specific color, evaluates ink amount set candidates based on printing results, allows user input of preference characteristics, and applies a color conversion lookup table to determine ink amounts matching user preferences, enabling the generation of a lookup table that outputs ink combinations aligned with user preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ink amount combinations are determined by a designer, then the color conversion lookup table can be generated with simple process, but the output ink combination may not match user preferences
Solution Approach 1:
The patent makes the color conversion lookup table dynamic and adaptable to user preferences. Instead of using fixed designer-determined ink combinations, the system allows users to input their preferences and automatically generates customized lookup tables that adapt to individual needs, resolving the contradiction between simplicity and user preference matching.
Solution Approach 2:
The patent changes the parameters of the lookup table generation process by incorporating user preference inputs as variable parameters. The system adjusts ink amount combinations based on user-specified preferences for different colors, transforming the static designer-determined approach into a dynamic parameter-driven approach that matches user expectations.
2Ease of operation
If multiple ink amount set candidates are evaluated and user selection is enabled, then user preference matching is improved, but the generation process becomes more complex
Solution Approach 1:
The patent performs preliminary actions by pre-calculating and storing multiple ink amount set candidates with their evaluated values before user selection. This allows the system to quickly present options to users without requiring time-consuming real-time calculations, thus reducing the perceived time loss while maintaining user preference matching capability.
Solution Approach 2:
The patent implements feedback mechanisms where users can select from pre-evaluated ink amount candidates based on their preferences. The system uses this user feedback to generate the final customized lookup table, creating an efficient iterative process that balances user involvement with time efficiency.
3Measurement precision
If color patches are output for user selection, then user input accuracy is improved, but additional printing resources are consumed
Solution Approach 1:
The patent creates visual copies of color patches representing different ink amount candidates for user selection. Instead of requiring users to directly specify complex ink parameters, the system generates visual color representations that users can select, improving input accuracy while using minimal ink for the patch generation process.

AI summary
A color conversion lookup table generation method includes the processes of (i) acquiring a set of parameter values which represents a specific color; (ii) acquiring a plurality of ink value set candidates which corresponds to the set of parameter values, and evaluated values each associated with a result of printing based on a corresponding one of the plurality of ink amount set candidates; (iii) allowing a user to input a preference characteristic of the user; and (iv) applying a color conversion lookup table which converts the set of parameters into a set of ink amounts which is determined on the basis the preference characteristic and the evaluated values.
