PROBLEM TO BE SOLVED: To accurately detect respiration rhythm from a body motion signal measured in movement regularly repeated.

SOLUTION: An extraction process for extracting respiration rhythm of an organism by subjecting a body motion signal which is a signal based on a repeating rhythm movement accompanying a voluntary movement of the organism to a filtering processing is provides. The filtering processing is executed to the body motion signal by using a time-constant determined based on an output done when the extraction process applies a band-pass filter to the body motion signal.
