INFORMATION PROCESSING APPARATUS, METHOD, AND STORAGE MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18625038 titled 'INFORMATION PROCESSING APPARATUS, METHOD, AND STORAGE MEDIUM
Simplified Explanation: The patent application describes a system that generates color profiles based on the color degeneracy of an input image, allowing for accurate color conversion and mapping.
- The system synthesizes an absolute colorimetric mapping table and a perceptual mapping table based on the input image's color degeneracy.
- It acquires first and second color profiles for color conversion and a parameter for adjusting color distances through gamut mapping.
- Using the acquired profiles and parameter, the system generates a third color profile for accurate color mapping.
Key Features and Innovation:
- Synthesizes color mapping tables based on color degeneracy.
- Acquires color profiles for accurate color conversion.
- Adjusts color distances through gamut mapping for improved mapping accuracy.
Potential Applications:
- Printing industry for accurate color reproduction.
- Graphic design for precise color matching.
- Photography for faithful color representation.
Problems Solved:
- Inaccurate color conversion due to color degeneracy.
- Lack of precise color mapping in digital images.
- Difficulty in achieving consistent color reproduction.
Benefits:
- Improved color accuracy in image processing.

- Consistent color reproduction across different devices.
Commercial Applications: Color management systems for printing companies, graphic design studios, and photography studios to ensure accurate color reproduction and matching.
Prior Art: Prior art related to this technology can be found in color management systems, color conversion algorithms, and color mapping techniques used in various industries.
Frequently Updated Research: Stay updated on advancements in color management systems, color conversion algorithms, and color mapping techniques to enhance the accuracy and efficiency of color processing.
Questions about Color Mapping: 1. How does color degeneracy affect color conversion accuracy? 2. What are the key differences between absolute colorimetric mapping and perceptual mapping in color profiles?
Original Abstract Submitted
Depending on a degree of color degeneracy of colors of an input image after absolute colorimetric mapping, an information processing apparatus synthesizes an absolute colorimetric mapping table and a perceptual mapping table. The information processing system can acquire a first color profile for performing colorimetric color conversion, a second color profile for performing perceptual color conversion, and a parameter for increasing a distance between colors mapped through gamut mapping, and generate, based on the first color profile and the second color profile and the parameter, a third color profile.
