摘要: The present invention relates to a device, system and a method for determining vital sign information of a subject. To provide an increased signal quality and an improved robustness of the obtained vital sign information with respect to motion and low SNR, the proposed device tries to find the linear combination of the color channels, which suppresses the distortions best in a frequency band including the pulse rate, and consequently use this same linear combination to extract the desired vital sign information (e.g. represented by a vital sign information signal such as a respiration signal or Mayer waves) in a lower frequency band.

摘要: The present invention relates to a device and a method for extracting physiological information from remotely detected electromagnetic radiation (14) emitted or reflected by a subject. A data stream (24) derived from detected electromagnetic radiation (14) is received, the data stream (24) comprising a sequence of signal samples representing a region of interest (58) exhibiting a continuous or discrete characteristic signal including physiological information indicative of at least one at least partially periodic vital signal (20), and being comprised of at least two wavelength components. The device further comprises a transforming unit for providing coefficient components from the at least two wavelength components and a coefficient selection unit for selecting the coefficient component which is used for calculating the desired signal component used for determining the physiological information.
