ANIMATE BODY DETECTOR

The subject oscillation frequency generating section generates a subject oscillation frequency in response to the capacitance of subject when the subject contacts the measurement electrode. The subject recognition signal generating section generates a subject recognition signal corresponding to the subject oscillation frequency. The reference signal setting section previously sets a reference signal used to determine whether the subject is an animate body. The animate body detection control section compares the subject recognition signal and the reference signal to determine whether the subject is an animate body.
