First, an extracting unit extracts chord progression of a tune to be reproduced. Then, a timing detector detects the timing of variation of the chord progression extracted by the extracting unit. Subsequently, an add-tone reproducing unit combines an add-tone with the tune to be reproduced according to the timing detected by the timing detector. The add-tone reproducing unit can also move a sound image to reproduce the tune or reproduce the tune as an arpeggio.

A heart-rate measuring apparatus is provided a database, acquisition unit, production unit, search unit, cross-correlation processing unit, and calculation unit. In the database, one or more sets of electrocardiogram (ECG) waveform data, serving as reference waveform data, of persons being examined are stored in advance. The acquisition unit acquires a heartbeat signal from a person being examined. The production unit produces ECG waveform data based on the acquired heartbeat signal. On the basis of the produced ECG waveform data, the search unit searches the database for reference waveform data of the person. The cross-correlation processing unit performs cross-correlation processing between the produced ECG waveform data and the searched reference waveform data, and the calculation unit calculates the heart rate based on the cross-correlated ECG waveform data using values of R-R intervals of the waveform.

While detecting a missing section from a biological signal acquired from a human body and while storing the biological signal values obtained at n (where n is a natural number) consecutive points in time, weighted addition is conducted on the biological signal values obtained at n points in time. In outputting its result as a final biological signal, the biological signal value at each of points in time included in the missing section is changed to an average value of the biological signal values at points in time which are not in the missing section.

Biological information detection apparatus

A heart-rate variability analysis apparatus comprises an electrocardiogram information detecting unit, heart-rate signal calculating unit, breathing signal calculating unit, and heart-rate-variability information providing unit. Of these, the electrocardiogram information detecting unit detects electrocardiogram information about an object to be diagnosed. The heart-rate signal calculating unit calculates a heart rate signal indicative of a heart rate of the object from the electrocardiogram information. The breathing signal calculating unit calculates, from the heart rate signal, a breathing signal in which a breathing state of the object is reflected. The heart-rate-variability information providing unit provides variability information of the heart rate of the object in which the breathing state of the object is reflected, on the basis of both of the heart rate signal and the breathing signal. Thus, the heart-rate fluctuations can be measure with higher-precision.
