Image Display Synchronization Through Centralized Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display systems in educational settings, such as classrooms, struggle to display the same image data seamlessly on multiple devices without requiring cumbersome adjustments, leading to potential image quality deterioration due to repeated image processing.
Innovation Solution
An image display system that includes a main device performing initial image adjustments and adding accessory data to the image data, which is then transmitted to sub-devices without further adjustments, ensuring consistent image quality across all connected displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image adjustment is performed on each image display device independently, then each device can display optimized image quality, but repeated image adjustments cause image quality deterioration
Solution Approach 1:
The main image display device performs image adjustment in advance on the image data before distribution. The adjusted image data is then distributed to sub image display devices, which display it without performing additional image adjustment, thereby preventing repeated adjustment and quality deterioration
Solution Approach 2:
The main image display device acts as an intermediary that centralizes the image adjustment function. It receives original image data, performs necessary adjustments, and distributes the adjusted data to sub devices, eliminating the need for each device to independently adjust images
2Illumination intensity
If multiple image display devices are arranged to ensure all students can see, then visibility for rear students is improved, but image adjustment operations become cumbersome
Solution Approach 1:
The main image display device performs universal image adjustment that benefits all connected sub devices. A single adjustment operation on the main device automatically optimizes images for display across multiple devices, eliminating the need for separate adjustment operations at each device
Solution Approach 2:
The main image display device serves as a central control intermediary that manages image distribution and adjustment for the entire system. Users interact with only the main device to perform adjustments, which are then automatically applied to all sub devices, greatly simplifying operation
Data Source
AI summary
The image display device includes an input unit that receives image data, a display unit that displays the image data received by the input unit, a receiving unit that receives drawing data drawn on the image data displayed on the display unit, an output unit that outputs the image data to another device, and a computing unit. The computing unit performs specific image adjustment on the image data, and causes the display unit to display the image data without performing the specific image adjustment on the image data when the specific image adjustment has been performed on the image data received by the input unit.
