BIOLOGICAL INFORMATION PROCESSING DEVICE, BIOLOGICAL INFORMATION PROCESSING SYSTEM, BIOLOGICAL INFORMATION COMPRESSION METHOD, AND BIOLOGICAL INFORMATION COMPRESSION PROCESSING PROGRAM
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.
