Distance learning system consists of not only the automatic camera system but also video transmission, multimedia technology and presentation system. More importantly, the distance learning system is a tool for education. Considering the context, we developed automatic camera system and the following results are obtained.1. The cameras have to be divided into two groups, one group of the cameras is for observation and the other is for shooting. This makes the design of camera system easy, because the observation problem and the shooting problem are separately designed.2. The observation cameras and the shooting cameras communicate each other via dynamic situation, which is defined based on what happens in the classroom. The observation cameras detect dynamic situation by observing the classroom, while the shooting cameras shot the objects based on the dynamic situation. This mechanism has an advantage to increase the kind of sensors for the observation.3. The camera works which are the rules on how to move the shooting cameras, can be written by each student in the remote place. In this case, we have to solve the resource assignment problem, and we solved it by the principle of the majority.

远程教育系统不仅包括自动摄像系统，还包括视频传输、多媒体技术和演示系统。更重要的是，远程教育系统是一种教育工具。考虑到这一背景，我们开发了自动摄像系统，取得了以下成果。摄像机必须分成两组，一组用于观察，另一组用于拍摄。这使得摄像系统的设计变得容易，因为观测问题和拍摄问题是分开设计的。观察摄像头和拍摄摄像头通过动态情境进行交流，动态情境是根据课堂上发生的事情定义的。观察摄像头通过观察教室来检测动态情况，而拍摄摄像头则根据动态情况拍摄对象。该机制具有增加观测传感器种类的优点。摄像机的工作原理是关于如何移动摄像机的规则，可以由每个学生在偏远的地方编写。在这种情况下，我们不得不解决资源分配问题，我们按照多数原则解决了它。
