Color Conversion Table Adjustment Cancellation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional color adjustment systems erroneously change colors similar to the first color when canceling the adjustment result of a subsequent color, leading to unintended changes in the color conversion table.
Innovation Solution
An image processing apparatus with a first adjustment unit for updating the color conversion table based on a selected target color, a storage unit for storing first and second color conversion tables, a cancellation unit for deleting adjustment results, and a second adjustment unit for re-adjusting the second color conversion table after deletion, ensuring accurate cancellation without affecting similar colors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single color conversion table is adjusted multiple times for different colors, then color adjustment flexibility is improved, but cancellation of a specific adjustment result causes unintended changes to similar colors
Solution Approach 1:
The patent segments the single color conversion table into multiple independent adjustment histories, each corresponding to a specific color adjustment operation. By storing each adjustment as a separate record with identification information, the system can selectively cancel individual adjustments without affecting others, thus resolving the contradiction between adjustment flexibility and result accuracy.
Solution Approach 2:
The patent implements a feedback mechanism where the system tracks the state of each color adjustment and automatically identifies and compensates for unintended changes. When a cancellation operation is performed, the system provides feedback about which adjustments are affected and performs corrective adjustments to maintain the intended color conversion accuracy.
2Reliability
If all adjustment results are canceled and re-applied when one adjustment needs to be removed, then adjustment result integrity is improved, but processing time and complexity increase
Solution Approach 1:
The patent extracts the specific adjustment result that needs to be canceled from the sequence of adjustments. By identifying and removing only the targeted adjustment record while preserving others, the system avoids the time-consuming process of canceling and re-applying all adjustments, thus resolving the contradiction between result integrity and processing efficiency.
Solution Approach 2:
The patent performs preliminary organization of adjustment results into separate, identifiable records before any cancellation operation. This preliminary structuring allows for efficient selective cancellation without requiring complete re-processing, reducing the time loss while maintaining adjustment integrity.
3Ease of operation
If adjustment histories are stored for multiple colors, then ability to revert specific adjustments is improved, but system complexity increases
Solution Approach 1:
The patent creates a universal adjustment history storage structure that handles multiple colors through a single standardized mechanism. Each adjustment record follows the same format with color-specific identification, allowing the system to manage diverse color adjustments uniformly without requiring separate complex structures for each color, thus resolving the contradiction between operational ease and system complexity.

AI summary
An image processing apparatus includes a first adjustment unit for adjusting a color conversion table, used for converting a color to be printed by a printer, by adjusting a selected adjustment color using the selected adjustment color and a target color, a storage unit for storing, in a storage apparatus, a first color conversion table generated by causing the first adjustment unit to adjust the color conversion table for a first adjustment color and a second color conversion table generated by the first adjustment unit to adjust a second adjustment color different from the first adjustment color after generation of the first color conversion table, a cancellation unit for deleting an adjustment result of the first adjustment color, and a second adjustment unit for adjusting the second color conversion table in response to the deletion of the adjustment result of the first adjustment color.
