Print Image Gamma Control for User-Selected Target Colors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming technologies lack the ability to select a target color that aligns with a user's desired output, leading to color correction that may not match the intended color.
Innovation Solution
An image processing apparatus and system that allows users to select a color reference mode (proof, fixed, or initial) to determine a target color, enabling dynamic color stability control based on user preferences and use cases, with the system incorporating a color stabilization processing unit to adjust gradation and gamma values accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a pre-stored output color is used as the target color in color stabilization control, then the color correction process is simplified and can be performed automatically, but the target color cannot be selected in accordance with the user's desired use case, leading to color correction that may not match the intended output
Solution Approach 1:
The system dynamically switches between different color reference modes (proof reference mode, fixed reference mode, initial reference mode) based on user selection. This allows the target color determination method to adapt to different use cases while maintaining automated color correction processing.
Solution Approach 2:
The system changes the parameter of color reference source by providing multiple selectable modes. In proof reference mode, the target color is determined from proof print results; in fixed reference mode, a predetermined color is used; in initial reference mode, the first print result is used. This parameter change enables both automation and adaptability.
2Adaptability or versatility
If multiple color reference modes are provided to accommodate different use cases, then adaptability and user preference alignment are improved, but the device complexity and operation interface requirements increase
Solution Approach 1:
The color reference functionality is segmented into three distinct modes (proof reference, fixed reference, initial reference), each serving a specific use case. This segmentation allows the complex functionality to be organized into manageable, clearly-defined options that can be presented to users in a structured manner.
Solution Approach 2:
The system provides self-service through automatic color correction based on the selected reference mode. Once a mode is selected, the system automatically determines the target color and performs gradation correction without requiring manual color calibration or complex user intervention.
