    • At the time of a normal operation, a second channel change message 30b is transmitted from the AP to each terminal before a time T0 until a channel change that is included in a first channel change message 30a elapses, thereby all terminals that received this message 30b, and the AP stop changing the channel. At the time of interference occurrence, setting a time until a channel change to be filed in a third channel change message 30d to a time equal to or less than a lapse time until the channel change at the time point of transmitting this message 30d to transmit it to each terminal from the AP allows the terminal that failed to receive the message at the time of the interference occurrence to make a channel change without causing a connection to the AP to be disconnected.
    • 在正常操作时,在时间T 0之前从AP向每个终端发送第二信道改变消息30b,直到经过第一信道改变消息30a中包括的信道改变,从而所有接收的终端 该消息30b,AP停止改变频道。 在发生干扰的时刻,将通道改变的时间设定为在第三通道改变消息30d中被提交到等于或小于经过时间的时间,直到在发送该消息30d的时间点的信道改变 从AP发送到每个终端允许在干扰发生时不能接收消息的终端进行信道改变而不引起与AP的连接断开。

    • A first image pickup means picks up an image of a real space, to thereby obtain a first background image.A first positional relationship estimating unit estimates, in a case where the first background image includes a first marker image being an image of a marker previously registered and located in the real space, a first positional relationship being a spatial positional relationship of the first image pickup means to the marker based on the first marker image, and estimates, in a case where the first background image fails to include the first marker image, the first positional relationship based on a displacement of a feature point extracted from the first background image.An image generating unit generates a first additional image based on the first positional relationship, and synthesizes the first additional image and the first background image, to thereby generate a synthetic image.
    • 第一图像拾取装置拾取真实空间的图像,从而获得第一背景图像。 第一位置关系估计单元估计在第一背景图像包括作为先前登记并位于实际空间中的标记的图像的第一标记图像的情况下,第一位置关系是第一图像拾取器的空间位置关系 基于第一标记图像对标记的装置,并且在第一背景图像不能包括第一标记图像的情况下,基于从第一背景图像提取的特征点的位移来估计第一位置关系。 图像生成单元基于第一位置关系生成第一附加图像,并且合成第一附加图像和第一背景图像,从而生成合成图像。
