Summary:To provide a communication terminal, a communication system, a communication method and a program that can automatically restore a screen sharing state being executed before conference disconnection, when the conference disconnection being not intended during a video conference occurs and a video conference is restored from the conference disconnection, to reconnect.SOLUTION: A communication terminal that shares display of a shared screen by transmitting information of the shared screen through a communication network to other communication terminal, comprises: a detection unit that detects disconnection between the communication terminal and the other communication terminal; a determination unit that determines a reason of disconnection when the disconnection is detected by the detection unit; and a screen sharing control unit that transmits information of the shared screen such that when it is determined by the determination unit that the reason of the disconnection is a communication failure in the communication network, acquiring of shared screen information is continued, and when the communication failure is restored, the acquired shared screen information is received in the other communication terminal.SELECTED DRAWING: Figure 5 【課題】ビデオ会議中に意図しない会議切断が発生し、当該会議切断から復旧して再接続する場合に、会議切断前に実施していた画面共有の状態を自動で復元することができる通信端末、通信システム、通信方法およびプログラムを提供する。【解決手段】他の通信端末に通信ネットワークを介して共有画面の情報を送信することによって共有画面の表示を共有する通信端末であって、他の通信端末との切断を検出する検出部と、検出部により切断が検出された場合、切断の原因を判別する判別部と、判別部により切断の原因が通信ネットワークでの通信障害であると判別された場合、共有画面の情報の取得を継続し、通信障害が復旧した場合、取得している共有画面の情報が他の通信端末で受信されるように、共有画面の情報を送信する画面共有制御部と、を備える。【選択図】図５
