1. An information processing apparatus comprising:

  • a communication-state determining section configured to detect a communication state value in transmission of a signal to a specific wireless tag to be searched and in communication with the wireless tag;

    a transmission-power control section configured to perform control to reduce transmission power of a signal to be transmitted from a radio section if a detected communication state value detected by the communication-state determining section is larger than a first threshold and increase the transmission power of the signal to be transmitted from the radio section if the detected communication state value is smaller than the first threshold;

    a transmission-power storing section configured to store, if the communication state value is larger than the first threshold, a transmission power value at the communication state value; and

    a transmission-power resetting section configured to perform, if the communication state value decreases to be smaller than a second threshold smaller than the first threshold, resetting of the transmission power on the basis of the stored power value stored in the transmission-power storing section and transmit the reset transmission power value from the radio section.
