ABSTRACT:
An information reception device comprising an imaging portion; a light reception portion for light reception of optional information subjected to optical modulation; a specification portion for specifying an optical modulation region contained in a capture angle of the imaging portion; a decoding portion for controlling the light reception portion in order to carry out light reception of the optical modulation region specified by the specification portion and decoding the optional information from the optical modulation content contained in the region; and a reproduction portion for reproducing the optional information decoded by the decoding portion. By acquiring a region essential for detection of optical modulation, acceleration of the information decoding process is achieved. Furthermore, position adjustment of the optical modulation region is easily accomplished.
