Device for Extracting Physiological Information from Remotely Detected Electromagnetic Radiation Emitted or Reflected by a Subject, and Method for Extracting Physiological Information from Remotely Detected Electromagnetic Radiation Emitted or Reflected by a Subject This invention relates to a device and method for extracting physiological information. remotely detected electromagnetic radiation emitted or reflected by a subject (10). a data stream (30) derived from electromagnetic radiation (20) emitted or reflected by a subject (10) is received. data stream 30 comprises a sequence (76, 152) of signal samples (78a, 78b, 78c) including physiological information and indicative of disturbing motion. signal samples (78a, 78b, 78c) represent at least one region of interest (68) that exhibits a periodic indicative pattern at least partially attributable to at least one physiological parameter (56), and a non-indicative movement region (110). ). sequence (76, 152) of signal samples (78a, 78b, 78c) is processed, comprising deriving a sequence (106, 158) of compensated samples from at least partially compensated for derivative motion (108a, 108b, 108c) total unwanted; detect a representative parameter for motion compensation accuracy; and deriving at least one characteristic signal (128, 172, 176) at least partially indicative of the periodic indicative pattern at least partially from the motion compensated sequence (106a, 108b, 108c), wherein the derivation of the characteristic signal (128, 172, 176) is performed depending on the evaluation parameter detected. 1/1resumo dispositivo para extrair informações fisiológicas da radiação eletromagnética remotamente detectada emitida ou refletida por um sujeito, e método para extrair informações fisiológicas da radiação eletromagnética remotamente detectada emitida ou refletida por um sujeito a presente invenção se refere a um dispositivo e um método para extrair informações fisiológicas da radiação eletromagnética remotamente de
