In this paper, we propose a new approach of synthesizing novel views in multiview camera configurations. We introduce the semi iV-view & iV-depth framework in order to estimate disparity maps efficiently and correctly. This framework reduces redundancy on disparity estimation by using information from neighboring views. The occlusion problem is handled by using cost functions computed with multiview images. The proposed method provides a 2D/3D freeview video. User can select 2D/3D modes of freeview video and control 3D depth perception by adjusting several parameters in 3D freeview video. Experimental results show that the proposed method yields the accurate disparity maps and provides seamless freeview videos.
