Claim 0:
1. A biometric information detecting device comprising:
a plurality of sensors measuring biometric information of a user, a first sensor of the plurality of sensors outputting an electrical signal;
a signal generator connected to the plurality of sensors, wherein the signal generator receives the electrical signal corresponding to a first waveform from the first sensor at a first time point, firstly processes the electrical signal corresponding to the first waveform according to a first reference condition to output a first result signal for the electrical signal corresponding to the first waveform, and secondarily processes the electrical signal corresponding to the first waveform according to a second reference condition different from the first reference condition to output a second result signal for the electrical signal corresponding to the first waveform, the electrical signal being a single input signal that is converted to both the first result signal and the second result signal;
a controller controlling the signal generator to process the single input signal according to a first electrical signal range and a second electrical signal range in the first reference condition and the second reference condition, respectively, wherein the first electrical signal range and the second electrical signal range are for the single input signal, the second electrical signal range corresponds to a dryer finger of the user than the first electrical signal range, and wherein the second electrical signal range is narrower than the first electrical signal range and included in the first electrical signal range; and
a processor connected to the signal generator,
wherein the processor receives the first result signal for the electrical signal and the second result signal for the electrical signal from the signal generator, synthesizes the first result signal and the second result signal to calculate a final result signal, and generates the biometric information of the user based on the final result signal.
