Description

本発明に係る通信装置は、第１のモードと前記第１のモードと異なる第２のモードとを有する通信装置であって、外部装置に映像データを送信する送信手段と、前記外部装置から前記映像データを生成するための所定の情報を取得できることを示す情報を検出したか否かを判定する第１の判定手段と、前記通信装置の動作モードが前記第１のモードから前記第２のモードに変更されているか否かを判定する第２の判定手段と、前記外部装置から前記所定の情報を取得する取得手段と、前記外部装置から前記所定の情報を取得できることを示す情報が検出された場合であって、前記通信装置の動作モードが前記第１のモードから前記第２のモードに変更されている場合に、前記通信装置の動作モードが前記第２のモードに変更された後に、前記外部装置から前記所定の情報を取得するように前記取得手段を制御し、前記所定の情報に応じて生成した映像データを前記外部装置に送信するように前記送信手段を制御する制御手段と、を有することを特徴とする。 Communication device according to the present invention is a communication device having a second mode different from the first mode a first mode, transmitting means for transmitting the video data to an external apparatus, from the external device First determination means for determining whether or not information indicating that predetermined information for generating the video data can be acquired is detected; and an operation mode of the communication device is changed from the first mode to the second mode. Second determination means for determining whether or not the mode has been changed, acquisition means for acquiring the predetermined information from the external device, and information indicating that the predetermined information can be acquired from the external device are detected. And when the operation mode of the communication device is changed from the first mode to the second mode, after the operation mode of the communication device is changed to the second mode, Above Control means for controlling the acquisition means to acquire the predetermined information from a section device and controlling the transmission means to transmit video data generated according to the predetermined information to the external device; It is characterized by having.

Claims
