Abstract: In a recording apparatus, a high-speed camera continuously shoots a series of images at a high shutter speed. Next, an MV calculating unit calculates motion vectors, based on a sequential relationship of the series of images shot by the high-speed camera. Then, a recorder records the images shot by the high-speed camera, together with the motion vectors corresponding to the images. On the other hand, in a reproducing apparatus, the series of images recorded by the recorder are reproduced, with the motion vectors recorded by the recording apparatus added thereto.
