Abstract
A data processing apparatus includes: a data acquisition unit that acquires waveform data corresponding to biological information correlated with a heart rate and generates, on the basis of the acquired waveform data, a plurality of pieces of time series data whose starting timings are different from each other; a correlation value calculation unit that calculates an autocorrelation value of the plurality of pieces of time series data for each of a plurality of lags; and an image generation unit that generates the autocorrelation image data in which the autocorrelation values are indicated for each of coordinates corresponding to a plurality of combinations of a timing and a lag by mapping pixel values corresponding to autocorrelation values corresponding to the combinations of the timing and the lag to a coordinate plane, in which the timing is assigned to a first axis and the lag is assigned to a second axis.
