Abstract: A current source estimation time determination method includes: determining an analysis interval in which a characteristic waveform is obtained with respect to one or more pieces of waveform data acquired by a sensor; estimating a current source with respect to a signal in the analysis interval determined at the determining; detecting a continuous movement interval in which the current source continuously moves in the analysis interval, using coordinates of the current source estimated at the estimating; and determining a single current source estimation time from the continuous movement interval detected at the detecting.
