Communication device and communication method
First Claim
1. A communication device for communicating with an external device using a human body as a signal transmission path, comprising:
- an electric field strength measuring unit configured to measure a noise level from a detected received electric field strength at the time of no signal after the received electric field strength is detected by the communication device when a transmission signal to be output to the external device is absent;
a transmission output determination unit configured to determine an output level of the transmission signal to be transmitted to the external device on the basis of the measured noise level; and
an output execution unit configured to output a transmission signal of the determined output level to the external device.

8. A communication method for communication between a first communication module and a second communication module using a human body as a signal transmission path, comprising:
-
detecting, by the first communication module, a received electric field strength at the time of no signal as the moment when the human body is in contact with the second communication module in a state in which a transmission signal is not started up when the transmission signal is output to the second communication module; measuring, by the first communication module, a noise level from the detected received electric field strength at the time of no signal; following, by the first communication module, a high/low state of the measured noise level and determining an output level of a transmission signal to be transmitted to the second communication module; outputting, by the first communication module, a transmission signal of the determined output level to the second communication module along with information of the measured noise level or the determined output level; following, by the second communication module, a high/low state of the information of the measured noise level or the determined output level and determining an output level of a transmission signal to be returned to the first communication module; and outputting, by the second communication module, a transmission signal of the determined output level to the first communication module.
