Mobile Device Automatic Image Quality Matching for Multi-TV Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When using multiple TVs to create a single large screen, differences in image quality due to varying panel and image processor specifications can be challenging for non-specialists to match, making it difficult for users to approximate a uniform display.
Innovation Solution
A method and device using a mobile device equipped with a camera to automatically match image qualities among multiple TVs by acquiring and comparing pixel values from each display, adjusting image quality correction values as needed to minimize differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual adjustment of image qualities is performed, then image quality matching between multiple TVs can be achieved, but the operation becomes complex and difficult for ordinary users
Solution Approach 1:
The system performs automatic image quality matching without requiring user intervention. The mobile device automatically captures images from multiple TVs, analyzes pixel values, calculates correction values, and transmits them back to the TVs, enabling the system to self-adjust and match image qualities across displays
Solution Approach 2:
The patent replaces manual mechanical adjustment operations with an automated digital system. Instead of users manually adjusting TV settings, a mobile device with camera and processing capabilities automatically performs image capture, analysis, and correction value calculation, substituting human operation with computational processes
2Ease of operation
If automatic image quality matching using mobile device camera is implemented, then user operation complexity is reduced, but additional device requirements and system complexity are introduced
Solution Approach 1:
The mobile device serves multiple functions: it acts as an image capture device (camera), an image processing unit (analyzing pixel values and calculating correction values), and a communication device (transmitting correction values to TVs). This multi-functionality reduces the need for separate dedicated calibration equipment, thereby managing system complexity while maintaining ease of operation
Solution Approach 2:
The mobile device serves as an intermediary between the user and the multiple TVs. Instead of users directly adjusting each TV or requiring complex professional calibration equipment, the mobile device mediates the process by automatically capturing images, analyzing them, calculating correction values, and transmitting results, simplifying the user's task while managing system complexity

AI summary
A display device, a mobile device, a system including the same, and an image quality matching method thereof are provided. According to the method, the mobile device acquires a first acquired image that is an image of a first displayed image being displayed on the first display device and a second acquired image that is an image of a second displayed image being displayed on the second display device, compares the first acquired image and the second acquired image with each other, determines an image quality correction value for the first display device so that an image quality of the first displayed image is made substantially equal to an image quality of the second displayed image, and transmits the determined image quality correction value to the first display device or the second display device.
