| Abstract(in English) | Recently, universities and other kind of schools begin to take an interest in a distance learning system. Such tendency is achieved in a background of easy transmission of video signals at low cost using communication networks. In general, video images of remote lecture is produced either by use of a single fixed camera or by mixture of plural cameras. The former image is easy to be monotone, the latter requires man power such as a director. We propose a method of producing lecture images taken by plural cameras which are automatically controlled by a computer. In our method, firstly we define a space information and time information for lecture images using Shannon's information theory, then plural cameras are controled by mutual information of these one. It is shown that the experimental results are highly rated in comparison with the case of a single fixed camera. |
