1. A receiving apparatus which is used while connected to a plurality of antennas, the receiving apparatus receiving a radio signal through the antenna to perform a predetermined process to the received radio signal, the radio signal being transmitted from a body-insertable apparatus inserted into a subject and including contents of an image taken by the body-insertable apparatus inside the subject, comprising:

  • a mode switching unit that switchably selects one of plural operation modes, the operation modes including at least a normal mode for reception of the radio signal and a performance inspection mode for inspection of performance of the antennas;

    an inspection signal generation unit that is configured to operate in the performance-inspection mode, and generates an inspection radio signal which includes image data similar to the image in the subject taken by the body-insertable apparatus;

    an inspection antenna that is configured to operate in the performance-inspection mode, and transmits the inspection radio signal to the antenna;

    a receiving antenna selection unit that is configured to operate in the normal mode, and selects the antenna which is suitable for reception of the radio signal;

    a sequential antenna selection unit that is configured to operate in the performance-inspection mode, and sequentially selects each of the plurality of antennas;

    a signal processing unit that performs a predetermined process to the radio signal and the inspection radio signal received through the antenna, the antenna being selected by the receiving antenna selection unit or the sequential antenna selection unit, anda display unit that displays in real-time a receiving status of the inspection radio signal transmitted from the inspection antenna, whereinthe performance inspection is performed during a predetermined interval of transmission of the radio signals from the body-insertable-apparatus inserted into the subject.
