Virtual Device Color Profile Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital devices struggle with managing colors in image files due to the lack of embedded device color profiles, which are often cumbersome to use and rarely employed by non-professionals, leading to inadequate color correction and storage efficiency issues.
Innovation Solution
A color management system that extracts metadata from image files to create color profiles, allowing multiple profiles to be associated with a single physical device through virtual devices, integrated into the operating system for centralized management and user-friendly interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ICC color profiles are embedded in image files, then color accuracy is improved, but file size increases significantly
Solution Approach 1:
The patent extracts the color profile data from separate ICC profile files and embeds only the essential color correction information within the image file itself. This selective extraction allows the image to carry its own color profile without requiring external profile files, thereby improving color accuracy while minimizing the increase in file size by including only necessary color data.
Solution Approach 2:
The patent creates a universal color management system where a single image file can contain multiple color profiles or adapt to different color spaces. The system enables one image file to serve multiple color correction needs through embedded profile data, allowing the same image to be accurately displayed across different devices without requiring separate profile files for each color space.
2Measurement precision
If manual profile assignment is implemented, then color management capability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements automatic profile assignment where the system itself selects and applies appropriate color profiles without requiring manual user intervention. The color management system automatically extracts metadata from images, identifies the appropriate color profile, and applies corrections seamlessly. This self-service approach maintains accurate color management while eliminating the complexity of manual profile assignment for users.
Solution Approach 2:
The patent performs color profile assignment in advance during image capture or import, rather than requiring users to manually assign profiles later. The system pre-processes images with appropriate color profiles based on device metadata, so that when users view or edit images, the color correction is already in place. This preliminary action eliminates the need for users to interact with complex profile selection interfaces.
3Adaptability or versatility
If multiple color profiles are stored per device, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent segments the color management system into distinct components: device information storage, profile data storage, and a mapping relationship storage. Each virtual device is segmented with its specific color profiles and characteristics stored separately. This segmentation allows multiple color profiles to be associated with a single physical device through virtual device abstractions, improving adaptability while managing complexity through organized data structures rather than complex hardware or software architecture.

AI summary
Management of color of image files in digital devices is described. A color management system can extract metadata from an image file based on a type of the image file. The color management system then creates a color profile based on the metadata extracted. The color management system further creates a virtual device, and assigns the color profile created to the virtual device. As such, multiple color profiles can be associated with a single physical device using the concept of virtual devices. Furthermore, the extraction of metadata and generation of color profiles can also be centralized in the color management system, which may be integrated into an operating system executable on a computing device.
