Dual Color Gamut Compensation for Consistent Display Color
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Different types of displays exhibit varying display characteristics, leading to inconsistent color representation when the same video data is input, affecting the user's viewing experience.
Innovation Solution
An electronic device equipped with a first and a second color gamut compensator, each loading a respective look-up table to convert the color gamut of video data, with one compensator in an idle state assisting the active compensator to enhance color gamut conversion efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple color gamut compensators are used to improve color representation accuracy, then color gamut conversion precision is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple color gamut compensators into a unified system where they work cooperatively. The first and second color gamut compensators share common functionality and can process video data through different pathways, merging their capabilities to achieve higher color conversion precision while managing device complexity through integrated design.
Solution Approach 2:
The color gamut compensators are designed with multi-functionality, where each compensator can operate independently or in conjunction with the other. The system can adaptively select which compensator to use based on the video data requirements, allowing a single device structure to serve multiple color conversion purposes.
2Speed
If color gamut compensators operate continuously to maintain readiness, then color conversion speed is improved, but energy consumption increases
Solution Approach 1:
The patent implements dynamic operation modes for the color gamut compensators. The system can switch between active and idle states based on processing needs, allowing the compensators to be fully operational when high color conversion speed is required and to enter low-power states when processing demands are lower, thus balancing speed and energy consumption.
Solution Approach 2:
The system employs periodic activation of the color gamut compensators rather than continuous operation. The compensators are activated in cycles or on-demand based on the incoming video data requirements, reducing overall energy consumption while maintaining adequate color conversion speed through timed processing bursts.

AI summary
An electronic device including: a first color gamut compensator configured to load a first look-up table storing first conversion data, wherein the first conversion data is used to convert a color gamut of video data including pixel values; and a second color gamut compensator configured to load a second look-up table storing second conversion data, wherein the second conversion data is used to convert the color gamut of the video data when the second color gamut compensator is in an idle state, wherein any one of the first color gamut compensator and the second color gamut compensator is further configured to convert a color gamut of each of the pixel values, by using the first look-up table or the second look-up table.
