Per-Display Image Correction for Unified Multi-Screen Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control systems fail to provide an overall sense of unity among multiple display devices due to differences in physical size, resolution, luminance, and color tone, leading to decreased visibility and occupant discomfort.
Innovation Solution
A display control system that includes an obtainer to gather device information, a calculator to determine correction values for each device, and a display to adjust images across multiple devices based on these values, ensuring uniformity in display characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display devices with different physical sizes, resolutions, luminance, and color tone are used, then the display system can provide more flexible display options and cover larger areas, but the overall sense of unity deteriorates and occupant discomfort increases
Solution Approach 1:
The patent applies local quality by adjusting display parameters individually for each display device based on its specific characteristics. The adjustment information is generated separately for each device, modifying local display properties (size, resolution, luminance, color tone) to achieve overall unity while preserving individual device flexibility.
Solution Approach 2:
The patent changes display parameters (size, resolution, luminance, color tone) of individual display devices based on measured characteristics. By dynamically adjusting these parameters through generated adjustment information, the system achieves uniformity across devices with different native specifications, resolving the contradiction between flexibility and unity.
2Adaptability or versatility
If display devices with different characteristics are used, then the system can accommodate various display requirements and positions, but the visibility deteriorates due to lack of uniformity
Solution Approach 1:
The patent modifies display parameters (size, resolution, luminance, color tone) for each device based on its characteristics and position. This parameter adjustment ensures that despite different native specifications, all devices provide consistent visibility and image quality, allowing flexible configuration while maintaining high measurement precision in terms of visual output.
3Device complexity
If no correction is applied to display devices with different characteristics, then the system complexity remains low, but occupant discomfort increases due to non-uniform display
Solution Approach 1:
The patent implements feedback by measuring the actual characteristics of each display device and using this information to generate appropriate adjustment parameters. This closed-loop approach automatically compensates for device variations, reducing occupant discomfort while keeping the system relatively simple through automated rather than manual adjustment processes.
Solution Approach 2:
The system performs self-adjustment by automatically generating correction information based on measured device characteristics without requiring manual intervention. Each display device effectively corrects its own output based on the generated adjustment information, reducing system complexity while eliminating occupant discomfort from non-uniform displays.

AI summary
A display control system includes an obtainer that obtains display device information on each of display devices, a calculator that calculates a correction value corresponding to each of the display devices, on the basis of the display device information, and a display that generates an image to be displayed across two or more display devices among the display devices. The display corrects the image to be displayed across the two or more display devices, on the basis of the correction value corresponding to each of the two or more display devices, and displays, across the two or more display devices, the image corrected.
