A video display apparatus is provided wherein even for ones, such as 32 pull-down and 22 pull-down, in which since the motion range of an original material is wide, there is a high probability of degradation of the precision of detected vectors, the processing time is effectively used to enhance the precision of detected vectors, thereby generating interpolated pictures having higher qualities. The apparatus recalculates, based on motion vectors (Va) used in generating the first interpolated picture, motion vectors for use in the next interpolated picture generation, thereby detecting recalculated motion vectors having higher precision and less errors than the original motion vectors. A repeated-picture determining part utilizes an interval, during which identical pictures requiring no vector detections consecutively appear, to further improve the precision of motion vectors.

An oxygen electrode used in the fuel cell and includes a plurality of carbon particles, a carbon thin-film, and surface nanostructure. The carbon particles are bonded to one another with the carbon thin-film, and the surface nanostructure is formed on the surface of the carbon thin-film. The surface nanostructure comprises catalyst nanoparticles made of platinum (Pt) and carbon nanoparticles. According to this combination of these elements, the catalyst nanoparticles are confined within three-dimensional structure to be formed by the carbon nanoparticles and are immobilized without losing space which allows any reactant to be accessed to the surface of the catalyst nanoparticles.
