Display Calibration System Maintaining Input Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display systems with multiple units often experience synchronization issues when adjusting input resolution or parameters, leading to re-synchronization, which can be time-consuming and result in loss of video signal, especially in high-reliability settings like events or meetings, and can negatively affect image quality if parameters are not correctly set.
Innovation Solution
A calibration system that maintains the input resolution constant during calibration, using processors to adjust settings like warp, blend, and OMTE parameters without changing the resolution, and calculates new system corrections to avoid re-synchronization, allowing for calibration without altering the input resolution and ensuring consistent image quality across display units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the input resolution is changed during calibration to match the displayed image aspect ratio, then the calibration accuracy is improved, but the video synchronization is lost and re-synchronization is required
Solution Approach 1:
The patent changes the calibration approach by modifying parameters other than resolution (such as warp, blend, and OMTE parameters) while keeping the input resolution constant. This allows calibration to be performed without triggering re-synchronization, thus maintaining video synchronization reliability while achieving calibration accuracy through alternative parameter adjustments.
Solution Approach 2:
The patent performs preliminary calibration actions by pre-adjusting warp, blend, and OMTE parameters before the actual calibration process. This preliminary preparation allows the system to maintain a constant input resolution during calibration while still achieving accurate calibration results through the pre-adjusted parameters.
2Manufacturing precision
If re-synchronization is performed to maintain correct resolution, then the image quality is improved, but the system speed is reduced and time is lost
Solution Approach 1:
The patent adjusts calibration parameters (warp, blend, OMTE) without changing the input resolution, thereby avoiding the need for re-synchronization. This approach maintains image quality through parameter optimization while preserving system speed by eliminating the time-consuming re-synchronization process.
Solution Approach 2:
The patent enables continuous calibration operation without interruption for re-synchronization. By performing calibration through parameter adjustments rather than resolution changes, the useful calibration action continues uninterrupted, maintaining both image quality and system speed.
3Stability of the object's composition
If multiple display units are synchronized together, then the display consistency is improved, but the risk of signal loss increases during parameter changes
Solution Approach 1:
The patent performs calibration on multiple display units by adjusting parameters (warp, blend, OMTE) independently on each unit while maintaining constant input resolution. This approach preserves display consistency across synchronized units while avoiding signal loss by preventing re-synchronization triggers.
Solution Approach 2:
The patent applies calibration adjustments to each display unit independently through segmented parameter modifications. This segmentation allows each unit to be calibrated individually without affecting the synchronization status of other units, thereby maintaining display consistency while minimizing signal loss risk.
4Adaptability or versatility
If calibration parameters are adjusted manually or automatically, then the calibration flexibility is improved, but the complexity of the calibration system increases
Solution Approach 1:
The patent provides calibration flexibility by enabling adjustment of multiple parameters (warp, blend, OMTE) through a unified approach that maintains constant input resolution. This parameter-based flexibility achieves adaptability without significantly increasing system complexity, as the constant resolution constraint simplifies the overall calibration process.

AI summary
This invention provides a calibration system and method for multi-unit display systems without a need for switching the system input resolution/configuration of the display system while calibrating. This serves to avoid carrying out a re-synchronization step. As such, this system and method allows for increases speed and reduced likelihood of failure. This system and method also corrects the display system by providing an arrangement that employs a minimum of required changes so as to avoid any changes that can consequently affect the output image of the display system. Calibration of the system of display units occurs free of any changes to the input resolution and this resolution is maintained in a manner that resists change unless specifically required. Moreover, this system and method enables a resolution for the overall system that differs from the sum of the input resolutions of the discrete, individual display units in the collection.
