Conventionally there exist two major methods to create mosaics in 3D videos. One is to duplicate the area of mosaics from the image of one viewpoint (the left view or the right view) to that of the other viewpoint. This method, which is not capable of expressing depth, cannot give viewers a natural perception in 3D. The other method is to create the mosaics separately in the left view and the right view. With this method the depth is expressed in the area of mosaics, but 3D perception is not natural enough. To overcome these problems, we propose a method to create mosaics by using a disparity map. In the proposed method the mosaic of the image from one viewpoint is made with the conventional method, while the mosaic of the image from the other viewpoint is made based on the data of the disparity map so that the mosaic patterns of the two images can give proper depth perception to the viewer. We confirm that the proposed mosaic pattern using a disparity map gives more natural depth perception of the viewer by subjective experiments using a static image and two videos.
