A color calibration device and method that includes a storage system for characteristic information and color calibration data measured by a color sensor, with a controller that calibrates the display apparatus using seed calibration coefficients and user-input settings through a graphic user interface, allowing for easy and accurate color calibration without the need for a separate color sensor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a color calibration device using a color sensor is used, then color calibration accuracy is improved, but the device becomes expensive and difficult to use
Solution Approach 1:
The patent creates a virtual color sensor by copying the measurement capabilities of a physical color sensor through software algorithms. The system uses the display apparatus's existing sensors and processing capabilities to simulate color measurement functions, eliminating the need for expensive external color sensors while maintaining calibration accuracy.
Solution Approach 2:
The patent introduces an intermediary processing layer that mediates between the display apparatus hardware and the color calibration function. This intermediary software component translates basic sensor readings into accurate color measurements through computational algorithms, bridging the gap between simple hardware and sophisticated color analysis.
2Ease of operation
If adjustment menus from display apparatus are used, then ease of operation is improved, but color calibration accuracy deteriorates due to limited adjustment items
Solution Approach 1:
The patent extends the limited adjustment parameters in traditional menus by introducing additional color calibration parameters such as gamma correction, color temperature, and white balance adjustments. These additional parameters are integrated into the existing menu interface, allowing users to access sophisticated calibration options without increasing operational complexity.
3Measurement precision
If color calibration is performed repeatedly to improve accuracy, then color calibration accuracy is improved, but loss of time increases
Solution Approach 1:
The patent performs preliminary color calibration measurements and stores reference data during manufacturing or initial setup. This preliminary action creates a baseline that accelerates subsequent calibration operations, allowing the system to make quick adjustments based on pre-established color profiles rather than performing complete measurements each time.
Solution Approach 2:
The patent implements a feedback mechanism that monitors color calibration results in real-time and automatically adjusts parameters to maintain accuracy. This continuous feedback loop eliminates the need for repeated manual calibration operations, as the system self-corrects to maintain optimal color performance throughout the display apparatus's operation.
