GPU Color Management for Multi-Display Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Achieving color consistency across multiple output devices is time-consuming and inefficient, as existing methods require manual adjustment and obtaining separate color profiles for each device, which can lead to discrepancies in multimedia content display.
Innovation Solution
A graphics processing unit (GPU) based method that queries a database of color profiles to determine a secondary color profile, compares it to a primary profile, and applies it to secondary displays to reduce color discrepancies, allowing for automatic color management and synchronization across devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment of each display is performed to achieve color consistency, then color accuracy is improved, but time consumption and operational complexity increase
Solution Approach 1:
The system performs automatic color profile selection and application without requiring manual user intervention. The GPU automatically queries the database, compares color profiles, selects the appropriate secondary profile, and applies it to secondary displays, eliminating the need for manual display adjustment while maintaining color accuracy
Solution Approach 2:
A database of color profiles is introduced as an intermediary between the primary display and secondary displays. This database stores multiple color profiles and enables automatic comparison and selection, serving as a mediator that facilitates color consistency across displays without requiring manual intervention
2Reliability
If separate color profiles are obtained and applied for each device, then color consistency is improved, but device complexity and operational steps increase
Solution Approach 1:
The system merges the color profile management functionality into a single integrated system. Instead of requiring separate manual configuration for each display, the GPU consolidates the process by automatically querying a centralized database, comparing profiles, and applying appropriate color profiles across multiple displays through a unified automated workflow
Solution Approach 2:
The database of color profiles serves multiple functions: it stores color profile data, enables automatic comparison between primary and secondary displays, facilitates selection of appropriate profiles, and supports application across multiple displays. This multi-functional system eliminates the need for separate manual configuration steps for each device
3Measurement precision
If visual comparison by human perception is used for display adjustment, then color matching accuracy is improved, but productivity and time efficiency decrease
Solution Approach 1:
The system replaces the mechanical process of manual visual comparison and adjustment with an automated computational system. The GPU automatically queries color profiles from a database, compares color data between primary and secondary displays using algorithmic analysis, and applies corrections without requiring human visual perception or manual intervention, thereby maintaining accuracy while eliminating time consumption

AI summary
A method includes querying, through a processor, a database of color profiles to determine a secondary color profile therefrom, and comparing, through the processor, the determined secondary color profile to a primary color profile of a primary display communicatively coupled to the processor. The method also includes selecting, through the processor, the determined secondary color profile to be applied to a secondary display also communicatively coupled to the processor upon determining that multimedia content displayed on the primary display with the primary color profile matches with the same multimedia content displayed on the secondary display with the determined secondary color profile. Further, the method includes reducing a color discrepancy between the same multimedia content on the primary display and the secondary display based on rendering the same multimedia content on the primary display with the primary color profile and the secondary display with the selected secondary color profile.
