A time-series-data processing device including: a leg-fluctuation-sequence identifying unit 3 that identifies a leg fluctuation sequence in time-series data X, the leg fluctuation sequence being a leg sequence in which rising legs and falling legs extracted by a leg extracting unit 2 appear alternately, and that counts a frequency expressing the number of legs constituting the leg fluctuation sequence and a window size expressing the range from the start time to the end time of the leg fluctuation sequence; and a database registration unit 4 that registers, as leg fluctuation data in a database 5, a set of the observation time at the start time of the leg fluctuation sequence identified by the leg-fluctuation-sequence identifying unit 3, the amplitudes of the legs included in the leg fluctuation sequence, and the frequency and window size counted by the leg-fluctuation-sequence identifying unit 3. |
