This paper propose a method for automatic recording of audience during the lectures based on the results from conventional studies of teaching process improvements. In the presented approach we propose the audience analysis features which are later used for proper camera settings in the lecture hall with the multiple cameras installed. We focus on the analysis of student activities during the lectures in order to select the regions with different features representing the cues related to the estimated lecture attendance levels. The experimental results of the application of the proposed system together with user comments are presented in order to evaluate the validity of our approach.
