Device, method, and program for inferring blood pressure information

Abstract

An object of the present invention is to provide a device for inferring blood pressure information that can infer blood pressure information conveniently. A device for inferring blood pressure information according to an embodiment of the present disclosure includes a moving-image acquisition unit configured to acquire moving images of a predetermined part of a living body captured at a first frame rate to detect a delay time between pulse waves in a first region and a second region separated by a predetermined distance in the predetermined part; a moving-image reproduction unit configured to reproduce the acquired moving images at a second frame rate lower than the first frame rate; a pulse wave extraction unit configured to extract a first pulse wave in the first region and a second pulse wave in the second region, based on the reproduced moving images; a pulse wave velocity calculation unit configured to calculate a pulse wave velocity from the predetermined distance and a time difference between peaks of the first pulse wave and the second pulse wave; a blood pressure information inference unit configured to infer blood pressure information, based on the calculated pulse wave velocity; and an output unit configured to output the inferred blood pressure information.
