1. A system for measuring a heart rate, comprising:

  • a database in which one or more sets of electrocardiogram. waveform data of a living body are stored in advance, the electrocardiogram waveform data serving as reference waveform data;

    an acquisition unit for acquiring a heartbeat signal generated in the living body;

    a production unit for producing electrocardiogram waveform data of the living body based on the acquired heartbeat signal;

    a search unit for searching the database on the basis of produced waveform data served by the produced electrocardiogram waveform data, to specify the reference waveform data of the living body from which the heartbeat signal has been acquired;

    a cross-correlation processing unit for performing cross-correlation processing between the produced waveform data and the specified reference waveform data; and

    a calculation unit for calculating an extremal value every period of time from data subjected to the cross-correlation processing and the heart rate based on the extremal value calculated every period of time.
