Abstract:
1. A body movement detecting apparatus comprising: measuring means which outputs, as at least one time-series signal, at least one result of measurement obtained by measuring body movement; detecting means in which, after slicing off a part of said at least one time-series signal output from the measuring means to generate a reference signal having a predetermined interval length from a predetermined position in said at least one time-series signal, the detecting means detects an intensity of correlation between the reference signal and each different part of said at least one time-series signal in a vicinity of the reference signal, the different part having the predetermined interval length; and determining means which, based on the detected intensity of correlation detected by the detecting means, performs one or both of determining whether the body movement is periodic, and determining a period of the body movement.
