Device, system and method for obtaining vital sign information of a subject

Abstract

The present invention relates to device, system and method for obtaining vital sign information of a subject (14). To enable reliably obtaining vital sign information of a subject, in particular of the subject's heart rate, the proposed device comprises an input unit (21) for obtaining a set of image data (31) detected from a skin portion (24) of the subject (14) allowing the extraction of the subject's heart rate (51) and a set of detection data (31, 41) detected from a body portion of the subject (14) allowing the extraction of the subject's respiration rate (53) or representing the subject's respiration rate (53), a heart rate extraction unit (22) for extracting the subject's heart rate from said set of image data (31) by use of photoplethysmography, a prediction unit (23) for predicting changes of the subject's heart rate based on the subject's respiration rate extracted from or represented by said set of detection data, and a control unit (24) for controlling one or more settings of said heart rate extraction unit (22) based on the predicted changes of the subject's heart rate.
