Image Display Order Synchronization in Communication Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conference systems face difficulties in changing the display order of shared images between communication terminals, as the location defined by X and Y coordinates does not effectively indicate the front or back position, making it challenging to reorder stroke images.
Innovation Solution
A communication system where the first communication terminal receives a change in the display order of images and transmits this information to the second terminal, allowing the second terminal to update the display order accordingly, using a hierarchical structure for managing shared information and locking editing to prevent conflicts during updates.

Engineering Contradiction Analysis
1Measurement precision
If X and Y coordinates are used to define image locations on a two-dimensional plane, then the position of images can be specified, but the display order (front/back position) of multiple shared images cannot be effectively changed or indicated
Solution Approach 1:
The patent introduces a Z-coordinate dimension to the existing two-dimensional X-Y coordinate system. This third dimension specifically represents the display order or depth position of images, allowing images to be arranged not only in spatial positions but also in a hierarchical front/back order. The coordinate system is extended from (X, Y) to (X, Y, Z), where Z indicates the stacking order of images, enabling effective control and indication of display sequence while maintaining precise position specification.
2Adaptability or versatility
If multiple images are shared between communication terminals, then collaboration is enabled, but synchronizing display order changes across terminals becomes difficult without causing conflicts or processing overload
Solution Approach 1:
The patent implements a feedback mechanism where when one communication terminal changes the display order of shared images, this change information is transmitted to other terminals. The other terminals receive this feedback and automatically update their local display orders to match, ensuring consistent synchronization across all connected devices without manual intervention or complex conflict resolution processes.
3Reliability
If display order information is transmitted between communication terminals, then synchronization is achieved, but additional data transmission and processing load increases
Solution Approach 1:
The patent extracts only the essential display order information (Z-coordinate or order identifier) from the complete image data for transmission between terminals. Instead of transmitting entire image files or comprehensive metadata, the system transmits only the minimal necessary information regarding display sequence, significantly reducing communication overhead and processing requirements while maintaining effective synchronization.

AI summary
A communication system includes a first communication terminal and a second communication terminal that shares a plurality of images with the first communication terminal. The first communication terminal includes first circuitry that receives a change of a display order of the plurality of images displayed on a display of the first communication terminal; and transmit information regarding the changed display order of the plurality of images to the second communication terminal. The second communication terminal includes second circuitry to change the display order of the plurality of images displayed on a display of the second communication terminal in accordance with the information regarding the display order of the plurality of images received from the first communication terminal. A method for communicating, performed by a communication terminal, the communication terminal, and a non-transitory recording medium executing the method for communicating are provided.
