摘要

device for extracting physiological information indicative of at least one vital signal from an individual of detected electromagnetic radiation transmitted through or reflected from an individual, method for extracting physiological information indicative of at least one vital signal from an individual of detected electromagnetic radiation transmitted through or reflected from an individual, system for extracting physiological information indicative of at least one vital signal from an individual from the detected electromagnetic radiation transmitted through or reflected from an individual, and, computer program the present invention relates to a device, system and method to extract physiological information indicative of at least one vital signal from an individual from the detected electromagnetic radiation transmitted through or reflected from an individual (14). the device comprises an input interface (30) for receiving a data stream of sensing data derived from the detected electromagnetic radiation transmitted through or reflected from an individual's skin region, wherein the sensing data comprises reflection or transmission information. dependent on at least two signal channels representative of respective wavelength portions, a signal mixer (32) for dynamically mixing the at least two signal channels to form at least one mixed signal, a processor (34) ) to derive physiological information indicative of at least one vital signal from at least one mixed signal and a controller (36) to control the signal mixer to limit the relative contributions of at least two mixed signal channels to form at least one mixed signal. and / or the rate of change at which said relative contributions may be altered. 1/1
