Abstract(in English) In this report, we propose a new method of analysis to understand a scene situation in multi-view shooting conditions using Android mobile phones. By analyzing the view directions of the phones based on mounted orientation sensors, we expect that the recognition of a scene situation without the contents of the shots. So, we improve our previously proposed method with analyzing the view-overlapping situation of multiple view-fields using the alpha blending technique. At first, we explain a prototype system to collect orientations from the phones in real-time. Also, we propose a method to visualize the overlapping situations of views by a definition of the distribution of importance in the view field as alpha texture and heat-map expression. Then, we evaluate the position of maximum and local maximum value in the integrated distribution of the blending of the scene with an actual position of a subject. And, we also describe experimental results to evaluate our proposed method.
