Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Screen colors may drift from true colors over time, leading to inconsistent color display.
Innovation Solution
An apparatus comprising a camera, a mirror, and a target, where the camera captures images of the mirror and target to calibrate the screen color by comparing and adjusting the color settings to match the target color, ensuring consistent color display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If screen is used continuously over time, then screen displays colors, but screen colors drift from true colors
Solution Approach 1:
The system performs periodic color calibration by capturing images of the screen through the mirror at scheduled intervals or based on usage time thresholds. This periodic action resets and maintains color accuracy without requiring continuous intervention, resolving the contradiction between extended usage duration and color precision.
Solution Approach 2:
The system captures images of the screen through the mirror, compares the captured colors against reference values, and automatically adjusts screen color settings based on the comparison results. This closed-loop feedback mechanism continuously corrects color drift, maintaining accuracy over extended usage periods.
2Measurement precision
If color calibration is performed frequently, then color accuracy is maintained, but device complexity increases
Solution Approach 1:
The mirror serves multiple functions: it reflects screen light to the camera for color calibration, and can be integrated into the existing screen bezel structure. This multi-functionality reduces overall device complexity while enabling continuous color monitoring and calibration.
Solution Approach 2:
The system uses the device's own screen as the calibration target, eliminating the need for external calibration tools or displays. The screen calibrates itself by comparing its own output through the mirror against reference color values, reducing external dependencies and system complexity.
3Measurement precision
If mirror is added to reflect screen light to camera, then color calibration is enabled, but device complexity increases
Solution Approach 1:
The mirror is integrated within the screen bezel structure, nesting the optical component within the existing device framework. This nesting approach minimizes additional space requirements and reduces overall structural complexity while enabling the color calibration function.
Solution Approach 2:
The mirror acts as an intermediary optical element that enables the camera to capture screen colors without direct line-of-sight requirements. This intermediary approach simplifies the optical path design compared to alternative solutions requiring complex lens systems or direct camera-screen contact.

AI summary
For screen color calibration is disclosed, a camera is disposed in a bezel of a computer. A mirror reflects light from a screen of the computer to the camera. A target is visible by the camera. A processor compares an image of the mirror and an image of the target captured by the camera. The processor further calibrates the screen color of the screen to match the target.
