摘要： For providing a living organism information detection system that is capable of extracting, with high precision and inexpensive structure, living organism information including a heartbeat signal, the living organism information system is configured to include a vibration detection unit acquiring simultaneously vibrations of multiple pieces of living organism information, an amplification unit having a first filter and a second filter with a longer time constant than the first filter, the first and second filters being inputted with vibrations of two pieces of living organism information, the amplification unit amplifying the acquired vibration signal so as to be in inverse proportion to the output signal of the first filter or the output signal of the second filter, whichever is smaller, and a discrimination unit discriminating between the two pieces of living organism information by comparing the amplitude of the amplified vibration signal and a threshold.
