<P>PROBLEM TO BE SOLVED: To correctly analyze an image with less calculation quantity even if an object of reading is photographed in an inclined state. <P>SOLUTION: Reference points arranged in positions which constitute four vertices of a parallelogram are installed in information being the object of reading. When an optical information reader reading and analyzing the reference points processes the image, the reference points are set to be lattice points and positions of the lattice points in the image which is photographed are decided (S2). The positions of the other lattice points in the image are sequentially decided by using position information on the lattice points which are previously decided (S4). The photographing is performed in a face parallel to the object of reading inside the thinnest lattice surrounded by the lattice points whose positions are decided (S5 to S8). A position in the image, which is adjusted to a middle point of a segment connecting the two lattice points in the object of reading, is decided in order as the position of the other lattice point. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
