Abstract (in Japanese) (See Japanese page) 
(in English) It is important problem that the quality of the output images can be degraded because of lack of information on occluded regions in the same frame, with free viewpoint images synthesized using reference images with their depth maps. Then, previously, we proposed the method of interpolating an output image using the background buffer updated dynamically in order to solve this problem. However, in this method, there is the problem which the occluded regions on the ground which exists continuously from a view to a background a front is not interpolated well. Then, this paper proposes the new method using the background buffers, which can express various shapes of backgrounds such as curved surfaces instead of the background buffer of the plane used by the conventional method, in order to enable a highly precise interpolation. The effectiveness of the proposed method was evaluated by several experimental results.
