Two or more images having a parallax therebetween are obtained by imaging a subject from different positions using imaging units. In determining the turn-on order, a temporary evaluation value element is obtained based on a distance between each undetermined matrix element whose position in the turn-on order has not been determined and each determined matrix element. The 3D rendering module includes: means for selecting a 3D theme; means for customizing the 3D theme with the 2D content; means for rendering the 2D content with the 3D theme into a plurality of frames in a 3D format; and means for combining the frames into a 3D video and outputting the 3D video. The ferromagnetic first fixed layer may be arranged on one of opposed principal surfaces of the ferromagnetic free layer with the first isolation layer in between, and the ferromagnetic second fixed layer may be arranged on the other of the opposed principal surfaces of the ferromagnetic free layer with the second isolation layer in between. The outside air is thus forcibly sent to the chamber room to thereby replace the inert gas remaining inside the chamber room with the outside air. The electrodes include multiple groups of segmented electrodes with each group of segmented electrodes having multiple segmented electrodes disposed at a same longitudinal position along the lead.
