<P>PROBLEM TO BE SOLVED: To provide an optical information verification device capable of picking up an image of a two-dimensional code which relatively moves and verifying quality of the two-dimensional code, in which degradation of detection accuracy can be reduced and verification can be further properly performed. <P>SOLUTION: In an optical information verification device 1, with a state in which a reference medium S, to which a reference code C is assigned, relatively moves at a given speed in a moving direction, an image of the reference code C is picked up by a light receiving sensor 23. On the basis of a length in the moving direction and a length in a cross direction orthogonal to the moving direction of a position detection pattern FP detected by detection means, and reference information stored in a memory 35, correction information which allows specification of a length per unit pixel in the moving direction and a length per unit pixel in the cross direction of the picked up image picked up by the light receiving sensor 23 is generated by correction information generation means (a control circuit 40). <P>COPYRIGHT: (C)2013,JPO&INPIT |
