Abstract
(EN)
In the present invention, a measurement unit (103) is attached to a subject and measures the acceleration in time series. A body motion calculation unit (104) determines the magnitude of body motion, which indicates the magnitude of motion of the subject, on the basis of the acceleration measured by the measurement unit (103). An anomaly point extraction unit (105) extracts, as an anomaly point, a time point at which the magnitude of body motion determined by the body motion calculation unit (104) exceeds a threshold value. An adjustment unit (106) adjusts a change in photoacoustic signal before and after the anomaly point extracted by the anomaly point extraction unit (105).
(FR)
La présente invention concerne une unité de mesure (103) qui est fixée à un sujet et mesure l'accélération dans des séries chronologiques. Une unité de calcul de mouvement corporel (104) détermine l'amplitude du mouvement du corps, qui indique l'amplitude du mouvement du sujet, sur la base de l'accélération mesurée par l'unité de mesure (103). Une unité d'extraction de point d'anomalie (105) extrait, en tant que point d'anomalie, un point temporal auquel l'amplitude du mouvement corporel déterminée par l'unité de calcul de mouvement corporel (104) dépasse une valeur seuil. Une unité de réglage (106) règle un changement de signal photoacoustique avant et après le point d'anomalie extrait par l'unité d'extraction de point d'anomalie (105).

測定部(103)は、被測定者に装着されて加速度を時系列に測定し、体動算出部(104)が、測定部(103)が測定した加速度より被測定者の動作の大きさを示す体動の大きさを求め、特異点抽出部(105)が、体動算出部(104)が求めた体動の大きさが閾値を超えた時点を特異点として抽出し、整合部(106)が、特異点抽出部(105)が抽出した特異点の前後の光音響信号の変化を整合させる。
