摘要:
The present invention relates to a device and a method for extracting physiological information from detected electromagnetic radiation (16) emitted or reflected by a subject (12). A data stream (30) derived from detected electromagnetic radiation (16) is received. The data stream (30) comprises a continuous or discrete characteristic signal (86) including physiological information indicative of at least one vital parameter (158), the characteristic signal (86) comprising at least one indicative signal component (88, 90) representative of a detected spectral portion indicative of the at least one vital parameter (158). The data stream (30) at least sectionally comprises at least one auxiliary signal component (92) detected along with the at least one indicative signal component (88, 90), the at least one auxiliary signal component (92) being representative of a distinct spectral portion. A characteristic signal discrepancy (100; 144) between at least one of the at least one indicative signal component (88, 90) and the at least one auxiliary signal component (92) is detected, the signal discrepancy (100; 144) being related to a physiological state of the subject (12). A signal calibration parameter (122; 148) is determined under consideration of the detected signal discrepancy (100; 144). Consequently, the at least one vital parameter (158) can be detected under consideration of the calibration parameter (122; 148).La présente invention concerne un dispositif et un procédé d'extraction d'informations physiologiques à partir d'un rayonnement (16) électromagnétique détecté émis ou réfléchi par un sujet (12).
