<p>PROBLEM TO BE SOLVED: To propose a time identification method, a time identification unit and a time identification system which takes into consideration the effect on the vicinity of correlation value. SOLUTION: In this invention, a correlation value at a time T (n) of interest and the least correlation value min among high correlation candidates are compared (step 1), when the correlation value at the time T (n) is smaller than the correlation value min in the high correlation candidates, as a result of the comparing, the time T (n) is made as a minimum change point and the process of interest is closed at the time T (n) (step 2), when the correlation value at the time T (n) is larger, the correlation value at the time T (n) is compared with the correlation values at the other times except the time T (n) (step 3), the identifier at the time T (n) is registered as a maximum change point when the correlation value at the time T (n) is maximum in the values at the other times, and as a minimum change point when the correlation value at the time T (n) is minimum in the values at the other times (step 5).</p> |
