Display Control Device for Multi-Terminal Image Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image display systems are cumbersome when switching between images from multiple terminals and often cannot display multiple images appropriately due to screen separation, making it difficult to share images effectively among multiple users.
Innovation Solution
An image display system that includes a display control device which receives images and position information from multiple terminals, determining the position of each image on a shared screen based on supplemental information to ensure accurate and intuitive display, allowing for seamless screen-sharing without the need for manual switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If screen separation method is used to display multiple terminal images, then multiple images can be displayed simultaneously, but the operation becomes cumbersome and images cannot be displayed appropriately
Solution Approach 1:
The display control device preliminarily determines the display position of each terminal image on the second screen based on the position information received from terminals before actual display. This preliminary positioning action eliminates the need for complex manual switching and arrangement operations, allowing multiple images to be displayed simultaneously in an intuitive and appropriate manner.
2Quantity of substance
If manual switching between terminal images is implemented, then only one image can be displayed at a time, but the switching operation is cumbersome
Solution Approach 1:
The system enables continuous display of multiple terminal images simultaneously on the second screen without interruption or switching. The display control device continuously receives images and position information from multiple terminals and maintains their display based on the determined positions, eliminating the time loss associated with manual switching operations.
3Quantity of substance
If screen separation is used to combine multiple images, then multiple images can be displayed, but the positional relationship of images is not maintained
Solution Approach 1:
The terminals provide position information feedback about their images on the first screen to the display control device. The display control device uses this feedback to accurately determine and reproduce the positional relationship of images on the second screen, maintaining the original spatial arrangement and improving positioning precision.

AI summary
An image display system includes a plurality of terminals each having a first screen and a display control device that controls a display device including a second screen. The plurality of terminals each transmit to the display control device an image of an active window on the first screen and image supplemental information including image position information indicating a position of the image on the first screen. The display control device receives the image and the image supplemental information, determines a position of the image on the second screen based on the image supplemental information, and causes the image to be displayed at the position determined on the second screen.
