Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrophotographic apparatuses face challenges in color variation due to process instability, requiring multiple calibration techniques and target values for different paper types, leading to increased user intervention and workload during calibration processes.
Innovation Solution
An image processing apparatus that integrates monochromatic and multi-color calibration capabilities, allowing for the selection of a common paper type for both calibrations, reducing the need for multiple target value registrations and simplifying the calibration process by using a single paper type for both monochromatic and multi-color corrections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple calibration techniques are employed for different paper types, then color reproduction accuracy is improved, but user workload and intervention requirements increase
Solution Approach 1:
The patent combines multiple calibration techniques (monochromatic calibration and multi-color calibration) into a single integrated calibration process. The control unit automatically executes both calibration types in sequence using the same paper type, merging what were previously separate operations into one unified workflow. This reduces user workload while maintaining color reproduction accuracy across different paper types.
Solution Approach 2:
The patent makes a single paper type serve multiple calibration functions simultaneously. The same paper type is used for both monochromatic calibration (correcting individual color channels) and multi-color calibration (correcting color combinations), eliminating the need for separate paper types for each calibration technique. This universal approach simplifies operation while achieving comprehensive color correction.
2Manufacturing precision
If separate target values are registered for different paper types, then calibration accuracy for each paper type is improved, but the calibration process complexity increases
Solution Approach 1:
The patent merges the registration of target values for different calibration techniques into a single registration process. The control unit manages one set of target values that serves both monochromatic and multi-color calibrations, eliminating the need for separate target value registrations. This reduces process complexity while maintaining calibration accuracy through the systematic execution of both calibration types.
Solution Approach 2:
The patent performs preliminary registration of target values that will be used for both calibration techniques. By establishing the target values in advance for the integrated calibration process, the system avoids the need for separate registration steps during actual calibration execution. This preliminary action simplifies the overall process while ensuring accurate calibration results.
3Manufacturing precision
If multiple paper types are used for different calibrations, then color correction effectiveness is improved, but the number of required paper selections increases
Solution Approach 1:
The patent merges the paper selection step into a single action that serves both calibration techniques. The user selects one paper type, and the control unit automatically uses this same paper type for both monochromatic and multi-color calibrations. This eliminates the need for multiple separate paper selections while maintaining the effectiveness of color correction through systematic calibration execution.
Solution Approach 2:
The patent makes a single selected paper type perform multiple calibration functions. The chosen paper type is used universally for both monochromatic calibration (correcting individual color channels) and multi-color calibration (correcting color combinations). This universal usage reduces the number of paper selection steps while achieving comprehensive color correction effectiveness.

AI summary
An image processing apparatus includes a control unit configured to control execution of monochromatic calibration and multi-color calibration, and a registration unit configured to register paper types of paper to be used at time of execution of the monochromatic calibration, a monochromatic target value set for each of the paper types used for the monochromatic calibration, paper types of paper to be used at time of execution of multi-color calibration, and a multi-color target value set for each of the paper types used for the multi-color calibration. The image processing apparatus executes the multi-color calibration, after executing the monochromatic calibration, via the control unit by using paper of a paper type selected from common paper types out of the registered paper types and the monochromatic target value and the multi-color target value set for the selected paper type.
