<p><P>PROBLEM TO BE SOLVED: To provide configurations for more certainly decrypting the respective information codes, and performing imaging and decryption processing of the respective information codes in shorter time in an information code reading system for using an information code whose recognition and reading are difficult under normal environment that visible light is irradiated and a second information code which can be recognized, read under such normal environment in combination. <P>SOLUTION: In an information code reading system 1, an imaging part 42 is provided with: a light receiving sensor 60 which receives light of an image from an information code formation medium 10 to output light receiving signals; and a signal selection part 82 which extracts and outputs a first correspondence signal corresponding to a first predetermined area (the area including a first information code C) from among the light receiving signals to be generated by the light receiving sensor 60 in a first period, and extracts and outputs a second correspondence signal corresponding to a second predetermined area (the area including a second information code Ca) from among the light receiving signals to be generated by the light receiving sensor 60 in a second period. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
