Summary device and method for extracting detected characteristic signal information and computer program The present invention relates to a device and method for extracting detected characteristic signal information. a data stream (26； 124a, 124b, 124c) derived from electromagnetic radiation (14) emitted or reflected by an object (12) is received. data stream (26) comprises a continuous or discrete characteristic signal (76； 132a, 132b, 132c) including physiological information (100) and a disturbance signal portion (94). the physiological information (100) is representative of at least one at least partially periodic vital sign (20； 156). the disturbance signal portion 94 is representative of at least one of a movement portion of the object and / or a non-indicative reflection portion. the characteristic signal (76； 132a, 132b, 132c) is transferred by converting at least three absolute components (92a, 92b, 92c) from the characteristic signal (76； 132a, 132b, 132c) related to the respective additive channels (74a, 74b). 74c) to at least two difference components (102； 142a, 142b) of the characteristic signal (76； 132a, 132b, 132c), wherein each of the at least two difference components (102； 142a, 142b) can be derived from a respective arithmetic transformation by considering at least two of the at least three absolute components (92a, 92b, 92c), wherein the arithmetic transformation comprises additive and subtractive coefficients. consequently, the disturbing signal portion (94) may be at least partially deleted in the transferred signal (32； 150). 1/1Mevcut buluş tespit edilmiş karakteristik sinyallerden bilgi ekstrakte etmek için bir cihaz ve bir yöntem ile ilgilidir. Bir nesne (12) tarafından yayılmış veya yansıtılmış elektromanyetik radyasyondan (14) türetilebilir bir veri akışı (26； 124a, 124b, 124c) alınır. Veri akışı (26) fizyolojik bilgiyi (100) ve bir rahatsız edici sinyal kısmını (94) içeren bir sürekli veya kesikli karakteristik sinyali (76； 32a, 132b,
