摘要

Summary device for extracting physiological information from electromagnetic radiation emitted or reflected by an individual, method for extracting physiological information from electromagnetic radiation emitted or reflected by an individual, and computer program the present invention relates to a device and method for extracting physiological information from an individual electromagnetic radiation emitted or reflected by an individual (12). a data stream (30) derived from the detected electromagnetic radiation is received, the data stream (30) comprising a first sequence (92; 152) of signal samples (94) indicative of various spectral parts. data stream (30) is divided into at least two deduced step sequences (96a, 96b, 96c) of recorded signal samples (94a, 94b, 94c), each of which deduced step sequences (96a, 96b, 96c). ) represents a defined spectral part (82a, 82b, 82c) and comprises time-spaced indicative signal samples (94a, 94b, 94c). Artificial samples (102a, 102b, 102c) are generated by consideration of nearby indicative signal samples (94a, 94b, 94c) so as to at least partially replace blanks (98) between indicative signal samples (94a, 94b, 94c), thereby generating a supplemented data stream (106). preferably, a spectral composition of the signal samples (94a, 94b, 94c) in the first sequence (92; 152) is alternately influenced. 1/1
