The paper deals with the problem of the optimal selection of the real views used for the virtual view synthesis in the free navigation systems. The practical free navigation system requires the real-time view synthesis. Therefore, the virtual view cannot be synthesized using the information from all the real cameras, but only few, most proper ones. In the paper the method of fast selection of two proper real views is presented. The proposed approach allows to select the real views for different camera arrangements, thus can be applied to the practical free navigation systems
