Generalized panoramic mosaic

(57) Mosaic-ization of summary video is usually used for making the view of a copy screen increase by the target by pasting many video frames together. According to the present invention, the method of mosaic-izing a picture to movement of the common camera containing the forward motion and zoom of a camera is offered. After calculating movement between a series of pictures, a strip is chosen from each frame so that a strip may become almost perpendicular to an optical flow. A strip is bent so that an optical flow may become parallel, this is pasted together, and the mosaic of a panorama is built. The conversion which is performed to a strip in order to make an optical flow parallel and to bend can be designed when the locus of a camera projects a picture aslant to the surface of the cylinder which makes a medial axis. Moreover, this invention おい conquered the influence of the azimuth difference of movement at the time of building an interim copy screen with a fine interval, and building the mosaic of a panorama using this interim copy screen between the original video frames, using the interpolation of a copy screen.
