A plurality of images are read in, two line segments which need be inherently parallel with each other in each of the images are designated, and a planar projective transform matrix is obtained from coordinates of end points of the line segments for parallelizing the line segments, thereby executing height normalization. The tire has a pair of bead cores, at least two or more axially inner plies greater than or equal to, extending between the bead cores, a crown reinforcement radially outward of the plies having a maximum belt width BW, and at least one flipper reinforcement wrapped around each bead core. The adamantane derivative and adamantane derivative each having the structure represented by the general formula and general formula, respectively, is a novel adamantylacrylate compound and useful as a monomer for functional resins such as a photosensitive resin in the field of photolithography. In a variant, polarization multiplex signals are produces and the resulting polarizations thereof in adjacent channels are perpendicular to each other.
