COMMUNICATION METHOD, TERMINAL DEVICE USING THE SAME, AND COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To share image data without increasing a burden on a server managing a network.

SOLUTION: A communication system 100 has a plurality of terminals 10 connected respectively through the network. Each of the plurality of terminals 10 participates in the network by a terminal device 10 to be a server. Participation in the network is managed by an arbitrary terminal device 10 designated by a user. In the network, terminal devices share mutual image data autonomously. When image data recorded in one arbitrary terminal device 10 is changed, the other terminal devices 10 are informed of the change of image data to synchronize image data to be shared. The other terminal devices 10 recognize the change of image data and acquire changed image data autonomously to update image data stored in their own memories.
