Image Processing Apparatus Color Vividness Threshold Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing color matching methods, such as Vivid Photo, may not effectively enhance the vividness of images, especially when colors are mapped near the boundary of a printer's color reproduction range, as the perceived vividness improvement is limited even when changing from Perceptual (photographic) to Vivid Photo.
Innovation Solution
An image processing apparatus that includes an input unit for color conversion instructions, a color conversion unit using a first color matching profile, and a display unit showing a message indicating a small effect on vividness if the color difference between images converted using different profiles is below a threshold, allowing users to adjust settings accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the color matching method is changed to Vivid Photo to make the image vivid, then the vividness of the image is improved, but the color difference between profiles becomes small when colors are near the boundary of printer color reproduction range
Solution Approach 1:
The system performs color conversion using multiple color matching profiles (first profile and second profile) and calculates the color difference between the converted images. This feedback mechanism allows the system to determine whether the vividness improvement is significant enough based on the actual color difference, enabling informed decision-making for users.
Solution Approach 2:
The invention changes the parameter of color matching method by providing multiple profiles (Perceptual, Vivid Photo, Saturation, etc.) and allowing selection based on the image content and desired outcome. The system dynamically adjusts which profile is applied by evaluating the color difference threshold, thereby optimizing the vividness effect while avoiding unnecessary changes when the difference is minimal.
2Adaptability or versatility
If multiple color matching profiles are provided to enable vividness adjustment, then the adaptability of the system is improved, but the complexity of the system increases
Solution Approach 1:
The system pre-calculates and stores multiple color matching profiles (Perceptual, Vivid Photo, Saturation, Match Color with Monitor Color) in advance. This preliminary preparation allows the system to quickly evaluate and switch between profiles without complex real-time calculations, reducing operational complexity while maintaining high adaptability.
Solution Approach 2:
The system automatically evaluates the color difference between profiles and determines whether to apply a specific profile based on the color difference threshold. This self-service mechanism reduces the need for manual intervention and simplifies the user interface, making the complex multi-profile system easier to use while maintaining versatility.

AI summary
An image processing apparatus includes an input unit configured to input an instruction to perform color conversion, a color conversion unit to perform color conversion based on the instruction by using a first color matching profile, and a display unit configured to display a message which indicates that an effect of color conversion on the vividness of an image is small, in a case where a color difference between the image on which color conversion has been performed by using the first color matching profile and the image on which color conversion has been performed by using a second color matching profile is less than a color matching threshold value.
