Abstract
Provided is a state recognizing device including: a first filter unit performing a filtering process on a time-series signal obtained by performing remote measuring on a space, in accordance with a first cutoff frequency to allow a signal component deriving from movement of a biological organism to pass through; a second filter unit performing a filtering process on the time-series signal in accordance with a second cutoff frequency to allow a signal component based on biological information to pass through; an amplitude-component extracting unit extracting a first feature quantity related to an amplitude component from a signal passed through the first and/or second filter units; a frequency-component extracting unit extracting a second feature quantity related to a frequency component from a signal passed through the first and/or second filter units; and a recognizing unit recognizing a state of the space by using the first and second feature quantities.
