In order alleviate a load pertaining to processing a signal originating from wave motion, the spectrum generation unit generates a high resolution first spectrum and a low resolution second spectrum on the basis of an input signal derived from wave motion detected by at least one sensor. The extraction unit extracts, from the second spectrum, a first peak satisfying an extraction condition in a target time frame. The tracking unit tracks, in the first spectrum, a second peak satisfying the extraction condition with regard to a time frame following the target time frame from which the first peak was extracted. The waveform generation unit generates a peak waveform, which is time series data of a frequency including a plurality of second peaks, using the first peak as a starting end.
