Abstract
There are included a standard deviation calculation unit that receives a plurality of acceleration data and calculates a standard deviation of the plurality of acceleration data for each specified time period, an average calculation unit that receives the plurality of acceleration data and calculates an average value of the acceleration data for each specified time period, a phase estimation unit that estimates a phase of the average value in a space having a first coordinate axis and a second coordinate axis by using the average value when the standard deviation is smaller than a specified threshold, and a phase correction unit that performs phase correction of the average value by using the estimated phase.
