DISPOSITIF DE TRAITEMENT D'INFORMATIONS BIOLOGIQUES, SYSTÈME DE TRAITEMENT D'INFORMATIONS BIOLOGIQUES, PROCÉDÉ DE COMPRESSION D'INFORMATIONS BIOLOGIQUES ET PROGRAMME DE TRAITEMENT DE COMPRESSION D'INFORMATIONS BIOLOGIQUES
This biological information processing device (10) is provided with: a peak detection unit (13) for detecting the peaks of a biological signal generated in a cardiac cycle; a waveform clipping unit (14) for clipping out a first peak-to-peak biological signal between two peaks, which are adjacent on the time axis of the biological signal, on the basis of detection results of the peak detection unit (13); and a resampling unit (15) for transforming the first peak-to-peak biological signal to a second peak-to-peak biological signal for a prescribed number of samples. The biological information processing device (10) is further provided with: an orthogonal transformation unit (16) for generating orthogonal transformation coefficients by performing an orthogonal transformation on the second peak-to-peak biological signal; a differential processing unit (17) for generating a differential signal for the orthogonal transformation coefficients on the time axis; and an encoding unit (18) for encoding the differential signal.
