    • A bridge controller, which controls relay between terminals including emission units and addresses assigned to the terminals, acquires coordinates of a light-received element in an light receiving unit at which light emitted from an emission unit is received, and stores the acquired coordinates in a location information table memory in association with a logical location on the network. Thereafter, it is determined whether or not the stored coordinates differ from newly acquired coordinates. When it is determined that the stored coordinates differ from the newly acquired coordinates, the logical location associated with the coordinates stored in the storage unit is controlled to be changed and stored.
    • 控制终端之间的继电器的桥接控制器,包括发射单元和分配给端子的地址,获取在接收从发射单元发射的光的光接收单元中的光接收元件的坐标,并将获取的坐标存储在 与网络上的逻辑位置相关联的位置信息表存储器。 此后,确定存储的坐标是否与新获取的坐标不同。 当确定存储的坐标与新获取的坐标不同时,控制与存储在存储单元中的坐标相关联的逻辑位置以进行改变和存储。

    • 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.

    • Recorded data is read by an image sensor from a recording medium on which the data is two-dimensionally recorded in a mesh pattern, and the read data is stored in an image RAM. The stored data is subjected to data decoding and error correction to reproduce target data. A scanning reference pattern of a mesh pattern recorded on the recording medium serves as a guide when the stored recorded data read by the image sensor is reproduced by scanning in the image RAM. A reproduction apparatus has a capability of coping with a partial destruction of the scanning reference pattern. Error checking codes are added to the recording medium in addition to the target data. These items of data are recorded as an encoded image after being subjected to scrambling processing and randomization processing. The reproduction apparatus can easily cope with an error when the encoded image is reproduced.
